You need to know a little about the VOIP protocol in use by your service provider. Then you can get the Session Initiator Protocol. With this info it may be possible to monitor the ip traffic on the line, sniffing for this to send your beacon message. Be advised I know little of this and have never tried it myself.
Welcome - I hope you find it inspiring, educational and practical. There is lots to learn and more to achieve.
@TheoL MySensors is not tied to the atmel328. It works on other MCUs too. I do agree with not wanting anything in the cloud, on wifi or bluetooth for security reasons.
It is not clear what will happen next - no announcements about what the intentions are for either the site or the project code. I guess time will tell.....
@Commodoreuno I can't see anything obvious at a quick look through, but I would suggest that you change all the delay() functions to wait() functions and comment out the serial print instructions and see how it goes then.
Does anyone have any suggestions for a 'directional' human presence sensor?
It needs only about 3-4M range but a 90 degree field of view would be ideal for corridor doorway detection.
I have seen some listed online but I believe that they have a 360 degree sense area and this would not be suitable for my application.
Well I was very saddened by the news that MYS site was shut down.
Yes there are alternatives but the flexibility to learn and develop independently without the data spying used by some big business was a huge plus for me. Having all the data at home and the ability to mix and match sensors tailored exactly to my requirements was just the job!
There were areas where this site could have been improved and that could have made more people stay and learn.. I think most new users gave up in frustration after just 2 or 3 posts.
I never heard of Code Garage before, but thank you for this bold move and long live my sensors!
Nice work there!
Thank you for sharing your success, I am sure there will be others who have an interest in this type of set up.
I found this if it is of interest (or not)...

@kiesel This is just my impression, nothing has been announced so it is guess work. But it took a week to get even one response to your question, and that says a lot.
Nothing comparable that I know of, but this all still works just as it always did and I have invested too much in hardware to leave it all and risk the same thing happening again.
I guess that at best the project has 'stalled' and at worst it is abandoned.
@NielBierman Simply add another RF gateway on a different frequency.
@DIY89 20cm is close - try moving them at least 2m apart - make sure all use sane radio channel - check wiring - use quality power supply - check no 'fake' components in the mix - use unique names for different nodes.
That's about all i can think of with the info you have provided.
Maybe the UNO is out of range of the GW? I don't see any problem with mixing different arduinos (or anything else) on the network so long as the network uses the same protocol and frequency....
Post the code for the nano working and the uno not working.
@nekitoss
I used 3.3V pro mini with regulator removed and powered by Vin pin. Also removed leds from the pro mini.
I used minicore bootloader.
I used the small pir sensors and again removed the regulator to power directly from the pro mini outputs.
After that sleep the node and trigger on interrupt.
Send battery level once a day.
Use inbuilt battery level monitor and not external components that constantly drain power to get battery level.
1.8V is 0% on the graph (not visible yet!) but I have had nodes working below 1.7V It's a matter of luck with that it seems.
Hope this helps you on the right track. I'll try and help if you want.
This is the latest image and still going strong after 18 months. Voltage is at 2.903V
Here is photo of the test example - I need to make a case and produce more of them over winter.....
Here is the same build/code of a window sensor. Similar time frame but hardly triggered.....
@NeverDie Thanks - Interestingly they show a free version on their site still. Did they revert due to bad publicity?
@NeverDie So how is it going for you? Have you tried USB devices with it? Did they work well? I am thinking of being able to run Win x64 SDR software on this but still wonder if it will work - Will try it out as soon as I can and report back. Meantime any hints or opinions you have would be good if you can share.
Each has advantages and disadvantages over the other - they are cheap and if I were you I would use one of each and do the 'magic' in the code. A small area like a hallway is OK for pir (assuming nobody is trying to defeat it) while radar cover a good area. hope this helps a bit, you don't give any detail on what you are trying to achieve.
@GaryStofer Hmmmm. I understand your situation and requirements but sadly I don't have an answer.
Only thing I can think of would be to try the node without the repeater function and see if that is in any way causing the issue. That would narrow it down considerably.
@JeeLet has hit on the RF module as a possible cause. Have you tried different module? Are all RF modules the same? Are all GW's the same?
@JeeLet said in ACK -aka ECHO beeing missed by Serial Gateway with RF24 radios. V2.3.2:
Waiting
"Waiting using the Arduino delay() command is not a good idea. " ... https://www.mysensors.org/download/sensor_api_20
Agreed - change delay(2); to wait(2); and see if that solves the problem
I suggest you take apart the node and give it a good clean - check for any tiny cracks or dry joints on soldered items and if using dupont connectors then clean thoroughly with isopropyl alcohol. Replace any connectors that don't clean up too well. =
Dirt and moisture can cause a lot of problems for electronics and batteries.
Sudden drops in voltage can also be caused by sudden drops of temperature or wind chill. I just posted a few days back a 1 year record of a PIR sensor with daily battery readings, it is not a smooth fall-off as most people might expect. I correlate the biggest sudden drop with a period of very cold and windy weather in February. It is in the battery powered section if you want to see it.
Finally as you have a 3.3V pro mini and power from 2xAA batteries I suggest you remove the battery monitoring from A1 and the associated components and instead use the internal voltmeter method.
Good Luck!
Latest MS version is 2.3.2 for a start. Also you need to reprogram the node and gateway with the updated library, make sure you update libraries within your Arduino IDE (if using it) and check for any changes from whatever version you have been running (you don't say about this) and the newer 2.3.2
There may well be some things in the node at least you need to address depending on what the node does.
Just completed 1 year of operation of a PIR sensor in the house that trigger 100-200 times a day. It is powered by 2xAA batteries and here is a graph of battery level over the year.
@ben999 You need flyback diodes across relay coils, this is not optional.
Some of the MQ senors require a 24hour+ burn in before they stabilise.
Also, check all wires for continuity and check all soldered joints for 'dry' joints, cracks or blobs. A photo of the project might help. REflow any solder joints to ensure good contact.
@elsereno I would investigate why the router goes down and fix that, unless your GW is the only thing using that router...
You can't do what you want using that sensor - The sensor is just a simple on/off type sensor that tells you if the sensor plate is wet or not, it does not measure how much rain is falling. Even if you timed how long it was activated how would you know between heavy rain and a light shower?
You need a 'tipping bucket' type sensor to give you an estimate of how much rain there has been, but even then you need to do some work with experimentation to get reasonable accuracy.
If you have not already seen it, "scammer payback" on you tube is fun to watch.
I used to get a lot of calls from China. Each time I'd block the number and report them. Eventually I have a dual system now where I don't answer calls that are not already in my phone book along with asking people who do accidently get through if they can't get a proper job or if their grandparents know how they make a living.
Last week I got the washing machine scam. She said my cover needed to be renewed. I told her I didn't know the company she claimed to be calling from and didn't have insurance with them.
She insisted I did and read my name and address again as if this was some sort of proof.
I told here to send me the renewall in the post with start and end dates of the existing contract, method of payment on the original contract and the make and model of my washing machine that is alledgedly insured with them.
I don't expect it will ever arrive......
@mfalkvidd Thank you for confirming that is how it works - so my next question is that if receive() is being called and functioning, but loop() is not - what happens to the messages with state change for a node child?
Clearly nothing within the loop() is updated (as it is not running) so messages received will be ignored until such time as loop() is able to process incoming messages? Or the state changes get lost?
To elaborate on my use, the issues is 'synching' LED lights with the controller after an unexpected power cut.
I have the nodes remember in eeprom their last state, but can't send that when the power comes back on as it takes a while for the controller and pi to boot and be running. If the nodes send it straight away the controller won't be available.
So a wait() in setup seems a way to do this, but with receive() running and loop() not then I am wondering what problems might occur if someone changes the lights state during this wait() period......
The nodes have IR senders for light control and IR receivers so that even if the manufacturers remote for the lights is used, then this is sensed by the node and the controller gets updated. This means that any method of changing the lights can be used and the controller always knows the status.
I suppose I could put the delay in loop() and only have it for the first run of loop() or I could add a before().... I have to give this some more thought!
So I can't figure this out -
If I use a wait() in setup(), will this delay running loop() and all other functions (like Receive() ) until after the wait() has timed out?
Will receive() still function even if a wait() is running in setup()?
Having a bad brain day it seems!
@CrankyCoder How far apart are the node and gateway? What is between them? Can you post any photos of of each with the wiring?
@CrankyCoder Do the data drop outs have any correlation to the solenoid valve operating and does the valave use the same power supply as the node MCU?
@CrankyCoder I have similar issue with a couple of nodes. Sometimes it looses signal for hours at a time...
It might be external interference from other devices like wifi, bluetooth or microwave oven.
It can also be connection issues especially with the push-on dupont connectors as when the temperature/humidity/air pressure change then the connectors can move slightly. Also they might be badly crimped in the first place.
So check all connections are good and can't move (soldering is best here), and then look for sources that might be an issue.
It could also be another node closer to the GW is sending at the exact same time as the problem node and masking the signal.
Batteries are susceptable to variations due to temperature too, they are a chemical reaction. So try a better source of power for testing too.
Looking at the code, send_status_message only ever sends 1 - is this what you want? It seems to never send anything else (like 0)....
Also you are using sleep but have a receive function - what happens to messages when the node is asleep?
You are sending battery level every second? That is too often. How long will the batteries last? This wastes battery power a lot. I check betteries once a day on my security sensors, they don't change for weeks at a time....
Have you modified the pro mini as per the battery page on this site? Have you added capacitors to the radio module?
directionControl seems like it will always turn off both digital pins regardless of the message as //disable are the last statements to be actioned?
You can try changing
#define MY_RADIO_RF24
to.....
#define MY_RADIO_RF24
#define MY_RF24_PA_LEVEL RF24_PA_HIGH
options for power are MIN, LOW, HIGH, MAX. - it might help.
@naruse GO through every bit inside and make sure that all grounds are connected to each other. A faulty grounding can have effects like this too....
@naruse There is a thin co-ax cable in the antenna that folds, maybe it is damaged and contact is only made in the folded position and not when straightened out. Try another antenna if possible.
Also, antennas are polarised. So rotating it might help as would small changes in position as reflections and absorbtion at 2.4GHz will be something that might affect the signal, just like with wifi (same frequency block).
As for touching it - you are either acting as a passive conductor for the rf since you might be in a place with better signal strength either that or the additional capacitance of your body is improving the resonance of the antenna. Difficult to tell which, but my guess would be the former.....
@vomaxa If you look at my post at the top of this thread (second posting) then all that still really applies. You need to list your requirements and then research until you find a compromise you believe to be the right one for your needs.
I also added a creality ender 5 plus a couple of years ago. This has a bigger build volume and is very upgradeable with new control boards from creality and third party vendors as well as having many common components to other printers in the range.
Whatever you decide it is a leraning curve and more frustrating than the promotional videos would have you believe. Still it is rewarding to make things that previously you couldn't at home.....
@ben999 said in nrf24+ module with stick antenna:
@skywatch oh great
thanks for that !
by removing the smd then the signal becomes "compatible" with a 2.4ghz stick antenna ?
It completely removes the strip antenna on the pcb as well as the matching stub. The component is likely a zero ohm resistor. So you will be taking the RF from the point before the antenna and it should work.
or shall i go with wire and adjust length ?
That is up to you! You could always try both and see what works best for you. It's only a few minutes work. Don't forget to post your findings for others to learn from...
@ben999 You may not gain much by doing this and things could even get worse.
But if you want to try then I suggest removing the component to the left of the blue arrow and then attaching some micro co-ax centre conductor to the left hand pad where the component has been removed (as we see it in the photo) and the screen going to the closest ground point.
@Larson A bit late as the dry weather has me doing outdoors work and I'm knackered!
But yes, I agree with your thoughts and method as a good solid starting point. I would clamp the modules in place so they cannot move at all and do first test, then solder wire to one module in situ and do test 2, then finally solder wire to second module and do test 3.
This way you get to cover all possibilities in the shortest steps and time with minimal messing.
@NeverDie I know what you mean, but "half a wavelength apart would have them in very close proximity with risk of interference. Better if the were 300mm+half a wavelenght apart. But can mysensors cope with 2 gateways on the same frequency? I didn't think that would be possible... Or were you thinking one gateway node with 2x RF modules? Now that would be interesting!
@Larson Will be interested in your results!! 
@NeverDie said in Most reliable "best" radio:
Regarding the antenna extensions, you raise some good points. The people who posted them seem like they thought it genuinely helped, but maybe I was gullible and was wrong to post the links. If so, I'm sorry.
We are all here to share and learn and help each other out - I was only adding my thoughts on the matter for all to consider.
On the other hand, it might take only 5 minutes to try them out and see whether or not they work. A simple trial experiment would maybe settle it one way or the other pretty quickly.
Yes it would, but positioning needs to be carefully maintained to avoid false results.
@skywatch said in Most reliable "best" radio:
Thanks. What was it you were wanting me to notice about the e32 library? If it was about the FHSS, that was an e34 module in the youtube video.
Oh darn it! - I got it mixed up - I am sorry for posting the wrong lib!
@NeverDie That 'antenna modification' just looks crazy to me, but I have not tried it. However the designers will have spent some time on getting the pcb stripline antenna to be matched to the transmitters impedance. Adding a random bit of wire on the end will screw this up royally.. You never see this on TV antennas or anywhere else for that matter (maybe some nutter with a car aerial made from a coat hanger).
Also I would expect that the design is to be as wide band as possible but centered on the mid frequency in the range available. So the further you move away from 'centre' frequency (Ch63) then the worse the antenna is likely to perform. But at the power levels used here the effects might be marginal. I have always found moving the RF board a cm or two can make a big difference in link quality.
Here is the link to the E32 arduino library..... https://www.arduino.cc/reference/en/libraries/ebyte-lora-e32-library/
@NeverDie It has an on-board frequency synthesiser so maybe during tx the temp rises on the substrate and this affects tx frequency stability? So it could be the FS rather than the PLL. Again just guessing here....
@NeverDie I suspect that in 'open loop' (i.e. no feedback as I understand that to mean) then frequency stability over a longer period might be questionable. So to be safe they recommend a limit across which frequency drift won't be noticable. But as always, I could be completely wrong!
@NeverDie I have not tried them for this particular application, but have used them for SMPSU and the larger clamp on styles for SDR and other RF devices.
They used to be quite cheap so trying a size that fits snuggly over the wires you are using should help.
I see that guy in the video you posted twisting the ground wire with the data wires. This could simply be adding capacitance to the circuit or acting as a common mode rejection against transient interference. I wonder why he didn't try different value pull-up resistors on the data lines to see if that would help.
@NeverDie You probably already considered this but using a co-ax cable for the power would offer some sheilding and also after watching the video you linked maybe some of those tiny ferrite beads on the data and power at the radio might be of help.
I had to chuckle when the guy in the video showed how he connected an external antenna without first removing the link to the PCB one!
If I can I will try one of the cdebyte modules on 3.6V and see if they are still good... Remind me in a week if I don't get it done!
@Larson Thanks- they are a LOT more expensive here, but cheaper versions are available - sorry for diverting the thread a little.
@NeverDie Maybe just ripple on the DC? Did you scope it to see? Maybe try with 10n , 100n and 470uF caps across the DC power line? - Or if there is an onboard regulator on the RF module, then maybe that gets more noisey as the voltage drop across it increases?
@Larson Do you have any links to this please? I found next doors 2 new cats killing 2 young birds they had paicked out of the tree and onto my lawn. The owners are un-cooperative on the issue and the cats have been using my garden as their own litter tray..... Garlic, chilli powder and vinegar have had no effect so I need to up the game!
@mariusl You don't need a separate nrf library - it is all built into the mysensors library. Remove the other libraries from your code, clear eeprom and re-flash using just mysensors.
@NeverDie said in Most reliable "best" radio:
Is there a battery chemistry other than Energizer lithium primary cells that you think might be the best overall choice?
I don't know enough about battery chemistry to make an informed contribution.
I have some lithium cells with 2040 date on, but not using them yet (probably in the next few weeks)....
Also, in the US, the FCC allows for the legal use of higher transmit power if using spread spectrum or frequency hopping (though there do still exist restrictions relating to dwell time and duty cycle). I'm no lawyer, but I get the impression LoRa counts as spread spectrum as far as the FCC is concerned. Without either spread spectrum or frequency hopping, the allowed transmit power is pretty low--more or less reliable only if the receiver is both nearby and line-of-sight with the transmitter. In my book that's not very practical. An example of that would be a plain vanilla Nordic nRF24L01, or the first generation z-wave, both of which had a max transmit power of just 0dBm.
The NRF24L01+ has frequency hopping capability - I tried it by modifying the tmrh library before I came to mysensors. I only made a slow hop rate (4 hops/sec) but it seemed to work nicely. It would be cool if my sensors supported this, but there is probably a good reason why it doesn't.
@NeverDie Interesting work and thanks for sharing it - I am sure it will interest many people trying to get the best out of their batteries.
The one thing I suggest is to also take measurements across the expected working temperature range. I don't pretend to know how much affect, but battery life is extended by storing them cool whilst in use a warmer temperature will allow more energy to be 'mined' from the battery (due to the chemical reaction).....
@JeeLet I am seeing the same issue for log in, so it is not just you, it is the site.
@epierre Capacitor advice is on mysensors pages.
@sindrome73 Has shown you very good advice and for the higher powered modules like this one I would replace the 4.7uF with a 47uF if you can. It will help stabilise voltage levels during transmit cycles.
Good quality stable power supply with good solid connections (properly soldered would be best) and capacitor - then try again.
What 5V1A power supplies are you using? Where do you get the 3.3V from?
Photo or drawing with more info on the parts you are using might save you a lot of time while we are all guessing at the moment.....
@epierre Did you read the user manual? - https://www.passion-radio.fr/index.php?controller=attachment&id_attachment=559
Have you added a capacitor as recommended?
What are you using to power the whole thing? My bet is that it is the power supply that is causing issues here. Can you post a photo or sketch of how it is all connected up?
@llasking Have a look on the arduino forum or github - I still use the older tmrh library for point-to-point on things made before I changed over to mysensors. There is also a nrf24-lite library as well, but I have never used it.
@Feliw05 You have left and right transposed. Looks like the left should go to Vcc and the right should go to ground....or are you looking at it from a different angle?
@tutur19 Either use a battery with a higher mAH rating or put 2 or 3 batteries in parallel to give more power.
Choosing a controller can be a headache, especially if you are new to all this.
@mfalkvidd gave some sound advice which I would like to add to.....
Do you want a paid or free controller?
How easy is it to install and update?
Do you need graphs or guages?
How do you want it to look (all controllers have some restrictions on how data is displayed).
What hardware do you want the controller to run on?
Do you want your data private or do you trust cloud services to hold your data?
How is data going to be sent to/from the controller?
How easy is it to add sensors, timers, rules, srcipts etc?
Hope you get a good decision soon!
What started this was my research into Dark Matter and Dark Energy discussions with Astronomers and Scientists. I wondered why a simple atom made of one electron around a nucleus of one proton and one neutron could remain stable when the electric charges would mandate an attractive force between the positive nucleus and negative electron. The electron can 'somehow' sustain its distance and therefore gets energy to overcome the attractive force. It can do this for millions of years with no 'conventional' input of external energy.
Right now the world could do with cleaner energy. Here in the UK 18,000 people die every year from avoidable pollution related illness.
I just hope the breakthrough comes in the west because if Russia or China leapfrog us on this tech then we are at a severe disadvantage.
I guess that 'solar power' would have been laughed at 2 generations ago (along with nuclear power, smart phones, space stations etc...) 
@yoshi824 Most of us have been where you are now!
I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn.
If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.
It is >10 years since this was published - still not heard of anything available to the public like this despite many patents on similar devices - Anyone here know more about the current state of this technology?
@Ethan-Chua In Arduino IDE, go to "Tools" -> "minicore" and select the board you are using from the drop down menu. Then underneath 'Tools' menu you will see all options for the bootloader. You should select these values to match your requirements.
@Roschkovsky said in Merging 2 or 3 sketches to one (relays & binary buttons):
if (!initialValueSent)
This is always false as there is nothing I can see to set it true.
Also, there is a LOT going on in the receive section - try to move the prints and logic to the main loop and just pass values from receive, it might save a lot of headaches...
@NeverDie Here are some you might consider - but if you possibly can try them first or make sure you can send them back if they do not perform as you expect.

@NeverDie I looked into those modules for a door announcement module, but on Arduino forum there were a lot of people having all sorts of issues with them.
@NeverDie You could use a mp3 player board (there are some with built in amplifiers) so that is one option. See the usual sellers online for info on them.
The other would be a pi zero and a small dac/amp combo. If it is outdoors don't forget that the speaker needs to 'tropicalised' to resist moisture or it won't last long with fog or humidity around.
@chey Yes it would be a good start - have as few repeaters as you can and don't sleep them or run them on batteries unless it's the only way you can do it. Also worth making small movements of the NRF module to see if it will improve range as a move of 10-50mm can make quite a difference to the quality of the signal.
@chey As far as I understand this is alrady possible to make all nodes 'repeater; nodes. But the downside is that this will generate more RF 'network' traffice ans could be counter productive.
Better to try out the 'tree' network first and make repeaters where they are the only other option.
Seems like a nice thing to have for simple things like this - not good for my sensors as that needs a lot longer to set up and transmit, but interesting all the same - I wonder if it is one or more magnet/coil arrangements that generate the power? Still, nice to have light switches that don't need any mains or battery power.
Just to wish those who celebrate it a Happy Christmas and of course a Happy New Year to you all!
Lets hope 2022 is better than 2021
@halipte The microwave 'radar' modules seem to trigger pretty fast - With PIR it depends a lot on ambient temperature of the area the pir is 'looking' at and the temperature of the moving object.
@frapell neg board should have been reg board (as in the regulator to go from 5 to 3.3V - When I did this a lot of issues I had went away. Take the 5V supply from the power supply input to the raspberry pi board. This means any current surge will be provided by the power supply and not from the pi itselff. I hope that makes sense.
@frapell If you can, get some small coax cable for wifi use and use that instead of the track on the PCB- Make sure it is grounded at the sending end - As for the power, I strongly suggest making a 5v to 3.3V regulator as the pi 3.3v can be quite 'noisey' - a buck regulater will help reduve this a lot. Don't forget capacitors on the input and output of the neg board. I did this for my pi set up too as it has the advantage of the radio getting power from the psu and not cia the pi. A linear regulator like the AMS1117 will do the trick.
@frapell I have the same network/phone cable tester as in the phto!- Hahaha.....
Back to the probem it does sound as if something is changing over time, that is why I suspect power supply, cables or connections. I guess you checked for dry joints on the pcb, vut it would be worth checking ecery pin has a firm connection with a multimeter and a spare dupont pin. Temperature difference can make a bigger difference then most people think.
Is the radion module connected to 5V on pi or 3.3V? this is another possible area to look at but I need to know this first...
finally, with good dupont cables, remove your pcb from the pi and connect it again using dupont wires 150mm or more away from the pi and try that. I am wondering if the RF path to the antenna being close to the gpio and cpu might perhaps be possible culprit. Is there any screening on the back of the pcb ?
I would look at 2 things here -
One, test all dupont connecters at both ends for a secure connection - I spent a loooong time chasing my tail due to dupont cables that were loose. Crimp them up with pliers if you have to.
Two, what power supply are you using? 'how are you powering the gateway and pi? What voltages do you get and are there any fluctuations when the GW radio is transmitting?
@Ethan-Chua Some photos of the wiring and set up would be of help here along with a link tothe radio modules you are using. Maybe try moving them further apart, counter-intuitive I know but it might be receiving module being swamped with the power of the TX one. You could also try a different channel (use nrf doctor to find where there are 'quiet' areas) and see if that helps.
Do you have a lot of bluetooth/wifi in the building? anything else in the 2.4GHz band like cameras, keyboard,mouse etc?
I remember that here (UK) they recommend that to balance a radiator you need to aim for 12C difference between flow and return pipes on the radiator. A couple od DS18B20s should do the trick. I have monitored flow and return to the gas boiler for many years now in this way.
@kacper_zet Try moving this code from receive to void loop and add a check to see if the status has changed from it's last state. Maybe then it will work for you.
digitalWrite(message.getSensor()-1+RELAY_PIN, message.getBool()?RELAY_ON:RELAY_OFF);
// Store state in eeprom
//saveState(message.getSensor(), message.getBool());
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.getSensor());
Serial.print(", New status: ");
Serial.println(message.getBool());
If not then it might be HA relsted and I can't help with that.
@topgun78 2 things to consider...
printing in PLA may not be a good idea for this as heating pipes can get to <70C and will softern the material and make it more brittle.
Use a stepper motor so that you can control it in microsteps to get 0-100% as sometimes it needs to be on at a lower level all the time. If just using open/closed you will get cycles of hot and colder room, not ideal.
@benhub When the UK left EU they immediately made aliexpress and others charge 20% VAT on top of the prices. AT about that time free shipping stopped being the norm and prices from China have been climbing in recent years.
It all adds up to more expensive hobby and me ordering fewer parts than I used to.
Ebay or similar sites might be an option as small sellers are not required to collect tax unless registered to do so.
Considering the chances of fake or 'failed test' components being sold makes it even more of a risk than when things were much cheaper.
I'd hate to caoculate how much I have had from China over the years that went quickly to recycling or landfill.
I guess in the end you could buy less from reuptable EU companies, at least you should get genuine items that way.
@benhub Sad news - I must get some more nrf24l01+'s - Also has anyone seen a PA/LNA version of NRF5? IF it is bluetooth device then I suspect not as it would be out of spec for that usage.
@jlb said in Radio stops working:
How to make the node detect this radio problem ?
I don't think there is a function to do this, but maybe someone else can help with that.
How do I get my sketch to do a cold restart of the radio ?
It would be good to see how you wired this all up - a hand drawn sketch or fritzing would do. I suspect that by modifying the way power is applied may need arjusting and come capacitors may need adding - You can reboot by using a hardware watchdog circuit (web search for it).
@TheoL Sound like a good time to update to the latest version. it is the best yet and very stable.
@canyouhearmenow That looks practical and useful - well done!
I think you need to post a clear drawing or photos of the setup and the code you are using.
I donlt know what you mean by "connecting the current in series" nor what "AC regulator" you are using or what "thermal serial currenr" is.
@Njwyborn I guess you checked that all the grounds are conneted. A photo of the setup you have might help. What are you using as a 'USB supply"?
@Njwyborn I think it is either that the USB cannot supply enough current and the voltage is dropping when the radio starts to transmit, or it is a noisy USB power port that needs more filtering (chokes, capacitors) to smooth it out.
If you are able to get a good quality 5v stable power supply from a reputable electronics supplier it may well solve the issue for you
Also wortha try is setting minimum transmit power and moving the node and gateway further apart. It may be that the gateway is saturating...
@zboblamont said in Solar/battery powering:
@rejoe2 Anti-freeze.
But then the hot water would not be suitable to shower/cleaning/pool etc and you then have to go to a heat exchange tank, somewhere to put it and insulate it and pipe to it. I am sure is can be done, but the fact that it is not 'standard' hints at it being costlly or impractical or both.
@rejoe2 Agreed! - But it's not OT as you could mysensors the hell out of such an installation!
@rejoe2 Thanks - i did not know about those. I still think that in Northern areas where frost and snow are common it is more of a risk, but it doesn't matter much as I do not consider going down that path!
I wonder why on commercial products we don't see any kind of heatsinks mounted beneath the cells to help wick away the heat?
Heat rises so they would probably not make a lot of difference except in the huge increase in weight on the roof timbers.
But yes - I always wondered why they didn't water cool the panels and use that hot water for the house hot water system or swimming pool. I suppose that would increase production and installation costs and complexity significantly as well as add more points of failure.
@mrmuszynski This might help....
https://www.mysensors.org/about/network
Sensors connect to nodes, nodes connect to the radio to send/receive sensor data via the gateway to the controller. Sometimes data flows the other way to control things like leds, relays, motors etc,
A node can have up to 254 children I believe, but that would be a bit much I think. As to how you have a lot of children, well, you could attach 7 switches to digital pins 2-8 and then have them as child ids 0-7 like this....
#define CHILD_ID_DOOR1 0 //D2 physical pin
#define CHILD_ID_DOOR2 1 //D3
#define CHILD_ID_DOOR3 2 //D4
and so on.........
Just make sure each child_id has a unique name and number or rhe presentation won't go too well......
@mrmuszynski I believe that it comes down to the fact that when mysensors include is 'run' it needs to already know the parameters it is running with. It can't start and then add things afterwards or it wouldn't know where to start.....For example, if it doesn't know what radio you are using it can't initialise it! ..... It's a bit like making a blueprint before building a house
Also of note is that you can use the same child_id on both nodes if you wish. It will not be a problem.
@mrmuszynski OK - I see 2 possible issues here.....
Your '#define' statements for your nodes and children need to be before the line #include<MySensors.h>.... This is most likely the issue here....if not...
remove the #debug from the gateway as this may be writing to the serial port and causing an issue, but I am sure it is the first thing above..
So node 1 shoule start like this.....
// Enable debug prints
#define MY_DEBUG
// Enable and select radio type attached
#define MY_RADIO_RF24
#define MY_NODE_ID 1
#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC
#define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion //sensor. (Only 2 and 3 generates interrupt!)
#define CHILD_ID 1 // Id of the sensor child
#include <MySensors.h>
uint32_t SLEEP_TIME = 1000; // Sleep time between reports (in milliseconds)
// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);
Change node 2 similarly and try again....
