Could i buy it assembled?

Tommas

Ok. Sorry. Working
--my-transport=rf24 --my-gateway=ethernet --my-port=5003 --my-gateway=ethernet

Hi,

I follow the instruction but i got

error.
The configuration was:
./configure --my-transport=rf24 --my-gateway=ethernet --my-controller-url-address=xxx.xxx.xxx.xxx

My controller is a VM and it has worked with an arduino gateway, but that go wrong, and i thought i try to use my rpi3 as an ethernet gateway. I connected the nrf24l01+ /pa/lna to it (5v, but i use an adapter for it such like this https://www.addicore.com/1x-nRF24L01-Adapter-p/ad279.htm )

please help

Hi!

I would like to wake up my pc over lan.
I thought that i make an arduino node with nrf24l01 and a ethernet w5100 to wake up my pc.
I need a sketch for it.
Does Anybody have it?

Thanks

Dear All!

I dont know what might be the problem.
Openhab2 2.4.0
Mysensors 2.3.0 binding
All other nodes are OK except my NoDE 3. Previously it had been OK until I upgraded to openhab2 2.3 , but Im not sure that the upgrade the main problem.
Please give me suggestion what should i try to fix this issue.

Message from gateway received: 3;1;1;0;0;5.2

Thanks in advance,

@tommas

It seems to work with the older mysensors binding:
org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar .

3 of my 5 nodes updated the values in openhab2 (2.3.0~20180331153334-1)

Tommas

@tommas

I think this issue is almost the same:
https://www.bountysource.com/issues/56097209-rfxcom-working-oh2-setup-stopped-working-after-reboot

Tommas

Dear All!

I updated openhab2 2.3.0 previous build (via apt-get) to 2.3.0-SNAPSHOT Build #1246 . 2.3.0~20180331153334-1
Except one of my node the nodes values arent updated on the sitemap, and arent written to the database, but in the openhab log I see the sent values, but:
Child X not present in node Y

Another problem on the paperui:
My mysensor ethernet gateway status on things page:
Status: UNINITIALIZED - HANDLER_INITIALIZING_ERROR Unresolved compilation problems: The type org.eclipse.jdt.annotation.Nullable cannot be resolved. It is indirectly referenced from required .class files The type org.eclipse.jdt.annotation.NonNullByDefault cannot be resolved. It is indirectly referenced from required .class files .

The strange is that one of my node's values are updating...

MY mysensors addon:
org.openhab.binding.mysensors-2.3.0-SNAPSHOT.jar

What might be the problem?

Please help,

Tommas

@korttoma

Thank you very much, and sorry....

Tommas

@gohan

Ok! After the "loop ended " the node should go to sleep. On the console I see these lines:
Loop ended
62763 MCO:SLP:MS=300000,SMS=0,I1=255,M1=255,I2=255,M2=255
62773 MCO:SLP:TPD

What does it mean?

Tommas

@gohan said in Arduino mini pro 3.3 battery optimization code:

loop

What kind of sleep is it? There are parameters out there. ADC_OFF and some and some... Is this sleep turn off adc?

Tommas

@gohan said in Arduino mini pro 3.3 battery optimization code:

LiFePo4 AA

THank You! I will try!

Tommas

@tommas

Should I use any other sleep "code"? How I know that the nrf24L01 go to sleep?

Tommas

@tommas

I did a new code, and it seems that it is do the job.
My goal was, that I only send the battery voltage (percent) when:
At least one of sensor value transmission occured + The battery report time is elapsed.

What do you think about my code? IT IS NOT ONLY MY CODE and it is not clear yet Thank for @gohan , @sundberg84 and mysensors for the base.

Dear @neverdie ,
Ok, so I wont use these batteries.

Tommas

@tommas

Dear All!

Can I use 2xAA 1.6V NiZn battery for 3.3V arduino mini pro?

Tommas

Hi All!

Im near to get it work:) .
Someone could write an example openhab2 thing and item for Battery Voltage handling?

Thank you!

Tommas

@gohan

Dear Gohan!

Thank you! I thought that it isnt equal with this: https://www.mysensors.org/download/sensor_api_20#sleeping ....
But perhaps I misunderstood something because you says that it is the same sleep mode...

Tommas

@sundberg84

Oh ok. I have put this in the code, so it is OK, i think. I thought that SLEEP_TIME isnt equal to powerdown, but it seems that i misunderstood.
I use your easypcb board Sundberg.... Is your battery measurement code better than this standard mysensors one?

Thank You again!

Tommas

Dear All!

I would like to use the Arduino Mini Pro 3.3 8Mhz (aTMega328) with 2xAA battery. I have read that it useful to put it in powerdown/sleep mode.
Could you help me what code/sketch should I use. I copied to here my beta sketch(It works, but it doesnt have the powerdown function)
If someone has any other suggestion related to the code, please write it!

@sundberg84

Or have you got any suggestion expansion board for arduino mini pro ? Something like this: arduino-pro-mini-undershield (but it can not buy on ebay)

Tommas

@sundberg84

Unofrtunately i havent got the skills and free time for a daughter board.:(. But doesnt have someone else a daughterboard?:)

Tommas

Hi All!

Could someone suggest me an elegant way to extend the mysx connector? SO i would like to multiple the A4 A5 pins onto another prototype board to use more I2C devices....

Tommas

Dear All!

I would like to connect my si7021 and bh1750 to the same arduino mini pro 5v. These use the I2C interaface, but i dont know how should wire it.
After the wiring, how can I read the values both of them with mysensors sketch?

Thank you for your help in advance!

T.

Tommas

@korttoma

So if i would like to use gateway for esp nodes i have to create an only esp gateway?

Tommas

Dear @mfalkvidd !

Is it under understandable?

Have a good day!

Tommas

Dear @gohan

Thank you! Superb!

Tommas

Dear all!

I have an mysensors ethernet gateway and nodes with nrf24 . I have an openhab2 controller. Could i use the above solution to program my nodes over the air through my current gateway? So i write my sketch on windows arduino and send it through my gateway to the node? Or i have to connect my computer direct to nodes over air?

Tommas

@mfalkvidd

Can I control/monitor the esp based sensors (which are connected to my AP, same network as openhab server) with openhab2 without any GATEWAY?

Tommas

@korttoma

Thank for all!
Can i use the ESP node over wifi without controller? Can i register these to openhab2?

Tommas

Dear All!

I have a mysensors ethernet gateway with nrf24. Now all my nodes communicate with it via nrf24.

I think that i would like to use some esp sensor nodes.
how can i connect these new esp nodes to this same gateway over wifi?

Thanks,
T

Tommas

Dear @Yveaux

I think that yes. The si7021 module has an smd 103 part on it. Maybe it is at the sda and scl but im not sure.

https://www.ebay.com/i/401364416322

Thanks

Tommas

@sundberg84

There arent any indication. Sometimes it works.... i tried another si7021 and same. Voltage is Ok. A connected the sda - A4 scl - A5 on easypcb board

Any idea?

Tommas

@sundberg84

What is the problem with my sketch? It is in developement phase, but the reading stops at this line, but sometimes it works for 3-4 loop...

Dear @mfalkvidd !

Thank you, and to everyone for the help!
I got it work!
If the sketch will be completed i will upload that!

Tommas

Dear @sundberg84

Thanks for the suggestions!
Another, which pin should i connect to the si7021? I cant find this info...

Thanks,

Tommas

Dear All!

Has anybody a sketch for this temperature and humidity sensor? I would like to use it with mini pro combined easypcb board.

Thank you in advance!

Tommas

Dear All!

Does anybody have mysensors compatible GUVA-S12SD UV sensor sketch?
I would like to operate it from 3.3V battery connected to Sensebender MIcro.

Thank you in advance!

Tommas

@Tommas

Cant nobody help me?

Thanks
T

Tommas

Dear @dbemowsk

I bought these: https://www.ebay.com/itm/401088383355

Thank you!

Tommas

@gohan

Oh OK! Thank you! The decision is hard for me, which solution i should use:) .

Tommas

Dear @sundberg84

If i use 5V regulated example, has it got 3.3V output for the sensors?

Thanks
T

Tommas

Dear All!

I would like to display the sensebender micro battery percentage in openhab2. How should I configure it in my openhab?

Thank you in advance!
Best regards,
T

Tommas

@gohan

Dear gohan!
I would like to power all my nodes from a central power source with 5V . I would like to use 3.3V microcontroller with 3V sensors... because of the voltage drop down caused by the distance (5-15m from the power source). Maybe there will be 1-2 battery powered sensor nodes..
This is my plan.
I dont like using battery. It is too hard for me to optimize the sensors for battery...

Best regards
T

Tommas

Dear @sundberg84 !
Thank you! ANd which example should i follow with this modification?
Thanks
T

Tommas

Dear @gohan !

Thank for your help!
Which configuratation should i use? Or do i have to modify one of the above configurations? (3.3V , 5V regulated, or 6-12V) ?

Tommas

Dear All!

I would like to use this PCB. I would like power it with 5V, but I would like to use a 3.3V version mini Pro. How should I do it? I would like to use it from 5V (USB adapter) or battery 2xAA . Could I do it?

Best regards,
T

Tommas

Dear All!

How can i get it work?: I would like to see that time the sensor sent the last value (last update). I would like to display it on the sitemap.
Please help me.

Have a godd weekend!

T.

Tommas

@MagnusF

YESS! It was the problem

Thank you very much!!

Tommas

@Nca78

Another question.
Can i use the mini pro's 3.3V output for all of my 3.3V sensors? Cant i exceed the current limit of the mini pro with these sensors?

Tommas

Dear @Nca78

Thank you for the long answer.
Could you suggest power module (in 5V ---> out 3.3V and 5V? I think something like with integrated microusb plug) what i can to build in to my circuit?

Best regards
T

Tommas

Dear @mfalkvidd

I think that i will use mini pro 3.3V version and in this case it is i will be capable to run it from battery or external power source.

Thanks
T

Tommas

@gohan

Dear gohan.

Sorry! I think about a general solution. We can forget the relay for now. I would like to know where is the limit approximatelly if i used battery with not too complocated circuits...

Best regards
T

Tommas

Hi @LastSamurai

If i powered a 3.3V mini pro from 2 AA (2000mAh) battery, how long my sensor node can work? Approximately..? NRF24L01 low power, MQ2, si7021, lm393 light, PIR motion, one relay module, and a sound sensor? Or these are too much for battery power?
Can I attach these directly to the mini pro power output?

Thanks,
T.

Tommas

@Tommas

Dear all!

Has someone any idea, why i cant display the mq2 value on the sitemap?
Only a "-" appear. I would like to see the value. On the control tab on the paperui i see the changes.
Another solution would be good as well, for example an alert if the mq2 value greater than X.

Thank you in advance!
T.

Tommas

@trasrik

I havent had got blob one yet so i havent got experience with it. But i red about the blob version and it should work....
But I suggest to you that you should buy these from reliable brand/shop. I think Itead or keyestudio are reliable brands. And i bought a pair nrf24 from ebyte, but it hasnt arrived yet.

Tommas

@gohan

It sounds very good, but i have started to use nrf24 with arduino and sensebender stuffs so i would like to continue with these ... but thank you for the suggestions because in the future i will test the esp solution.

I havent decided yet which arduino i use... the sensebender micro is very good because it has good quality humidity ad temp sensor integrated on it, but it is a bit expensive... arduinpro mini with the same temp sensor is max 6-7USD

Tommas

@gohan

Dear gohan!

Does This mean that every node has an IP address and communicate with the gateway over my WiFi network?
Thanks
T

Tommas

Hi @LastSamurai

Thank you!

Which mini pro do you suggest? The 5V version?
What about the nano? It is about the same price as mini pro.

Have you got reliable buying source?

Thank you!
T

Tommas

Dear All!

I would like to place sensor nodes to all of my rooms.
I plan, that i will power these from a central power source (12V or 5V).
The distance between a node and the power source will be max 20m.
I would like to ask your opinion about:

which microcontroller do you suggest? (arduino nano, mini, sensebender micro) sensors will be: 1-2 relay, gas sensor, temp+hum, light, sound, motion
should I power with 12V or the 5V is enough?
Where do you buy low cost enclosure (something with nice design)?

Thank you in advance!

Best regards,
T.

Tommas

Dear @TimO

Unfortunately it isnt enough. A - sign appeares but the value missing

Best regrards
T

Tommas

Dear All!

I dont know exactly what i did to make it work, but it is almost OK now.
Almost, because on the PaperUI the Control tab shows the right value of the Air Quality Meter, but on the BasicUI sitemap and in the OPENHAB ios APP shows only the Text (Air Quality ...) without the value

I attach the new sketch and code, if somebody could help me:

Dear All!

I would like to configure my ethernet gateway + NODE 1 (DHT+MQ2) sensor node with openhab2

Some friends from here helped to me , so i could create the node's sketch. The temperature+humidity works, but i cant make the mq2 sensor work. I use the airquality sketch for it mixed it with the temperaturehumidity sketch.
The openhab get the value from the mq2 (based on the logs) but i cant display it on the website.
I have just seen that based on this table Controller table the airquality is not supported in the openhab 2 + mysensors . Is it true?

Node's sketch:

Dear Gohan!

I realized that I can not transfer the gas sensors calculated value through the V_LEVEL variable used in the sketch, because on the openhab side i should use tripped type value i think...
So i think there is a missconfiguration between openhab item/sitemap configuration and the sketch.

The goal would be to display the mq2 sensor's calculated value, which i can use for alarm in the future, but now i will be happy about the value:)

Have a good day

@mickecarlsson

Thank you very much guys!

I had to modify things for openhab, it is better now. But...
in openhab2 i get this in the log:
2017-07-24 19:23:36.497 [DEBUG] [rs.internal.gateway.MySensorsGateway] - Child 2 found in node 1
2017-07-24 19:23:36.498 [WARN ] [rs.internal.gateway.MySensorsGateway] - Variable V_LEVEL not present

Does someone know what i missed?

Good afternoon!

@gohan

Hi Gohan!

Thank you again for your help:)

I have uploaded already but i see that the link dont work.
I added comments to the MQ2 sections

Dear All!

My project: Node + EthernetGW + openhab2

I try to combine the two example sketch codes (I would like to trigger the MQ2 sensor for smoke) , but it seems that the node sends the MQ2 sensors values, but
-the gateway dont read that, and
-i think that the node send the data more frequently than it should do.

@TimO

I found the answer to my question:) https://forum.mysensors.org/topic/4462/gatewayw5100-unable-to-get-working-w-v2-0-0/2

But why the downgrade should be a solution? The latest version Arduino AVR board doesnt compatible with all clone?

Thanks, T

@TimO
Dear TimO!

What does downgrafing the board definition means?
Im beginner sorry

Have a good day!
T

Tommas

@rejoe2

I see. I hope, i can use it for a while:).
I think im closed this topic. The solution was to change the nrf24 modules, because i could not pair them.
The anoother problem was that i use two power source, and i didnt common the GND.

Thank you everyone who helped to me!

(I run into another problem, if you had some free time:) openhab-mysensors-ethernet-gateway-value-missing

Tommas

Dear All!

My problem is, that openhab 2.2 (snapshot) show my gateway + temp + hum things online, but values are missing.
(additional info, that first I installed openhab2 stable (same results) with apt, after it i change the repo to snapshot and installed it with apt upgrade)

The sensor node sends the temp and hum values to gateway, and i see that the gateway receive these., but in openhab no values.
I followed these:
https://www.mysensors.org/build/ethernet_gateway

@rejoe2

Thanks for the suggestions.
Had you got problems with nrf24?
Tomorrow i will try to configure openhab. I have tried to find a quick up to date guide for openhab 2 + mqtt mysensors but font find one.
Mysensors said that their bindigs support only ethernet or serial gateway officially.
I dont understand what is the diff (or why mqtt used mostly) the ethernet and mqtt solution but i have started the mqtt already.

Best regards
T

Tommas

@rejoe2

Hi rejoe2!

What kind of nrf24 do you use, and where did you buy these?
I think that you use capacitor as well, and stable 3.3V dont you?
Do you think that this shield is good for my node? It would be very good if i didnt have to use cables for nrf24....
https://www.itead.cc/wiki/Arduino_Nano_IO_shield

Best regards
T

Tommas

@gohan

On ebay, i cant find the bypass capacitor in the specs. I have written to a seller asked about it. I will report to you about the answer.

I have tried once again the two high power nrf24 pa+lna (I put foil onto these) but these dont work. I think these are broken or very very bad ones.

Could you suggest to me a seller who sells High power nrf24 which ones you have got good experinces?

Thanks,
T

Tommas

@rejoe2

Dear rejoe2!

Thank You for the infos.
Than i will buy two of this ebay version.

Best regards,
T

Tommas

@gohan

Oh! I missed that. I will look for another one with cap.

Tommas

@gohan

Dear gohan!

Thank you for your help. I will buy from ebay this one: https://www.ebay.com/itm/200960749614

And im planning that i will buy a shielded nrf24 pa+lna .
Today im installing an openhab and try to transfer the datas from gateway to the openhab...

What projects have you done already?

Best regards
T

Tommas

@gohan

Dear Gohan!
Everyone suggests that if you use pa+lna version you should power it from external regulated 3.3 V because the arduino clones 3.3V isnt strong enough. So i bought externaI power source.... i have figured out today that i can common the power source's gnd with the arduino gnd. It is working....

What is last that i would like to power the arduino uno from power module 5V and connect it to my computer same time... i dont know how to do it.

I have tested the two nrf24 pa+lna and these arent working together only. Separately is OK.

I will go with the standard nrf24 , make it working than i will try to buy branded nrf24 pa+lna.
Have you got favourite brand for cheaper electronic parts?

Tommas

Dear Gohan!

I have just tried the new nrf24 standard, and it works!
It seems that the GND should be common (im newbie).
I would like to test further with the pa+lna version, but....
I have an other question.
I would like to power the board with 5V from the power module 5V output, and i would like to program the board via USB at the same time. How should i connect the power module to the board?

Dear gohan!

Sorry, it is a private home server and it was in maintenance mode when you were trying to connect. Now it should be working.
(The new nrf24 have just arrived so im going to try these as soon as i can)

Best regards

@gohan

Oh ok. Thanks.

I tried to attach 100uF capacitor but the results are same.(no reply) . The node ID is defined, the parent ID isnt.
It seems that im out of ideas. I wait for the new nrf24 without pa lna.
Im attaching some pictures about the project.
Should i foil the nrf24 modul?

Hi Ben!

How can i define the parent id on the gateway?

Thanks

Hi Ben!

I havent define the parent ID because i havent known that i should do. i will try these settings as soon as i can.

I have already defined the node id in the node sketch

Thank you!

Hi gohan!

Oh, OK! Im trying today. How can i set the power to minimum?

Have a Good day!

Dear gohan!

I have tried but nothing change. I bought two nrf24 from keyestudio without pa/lna , if it arrives i will try those.
I will write the experiences with the new ones.

Best regards

Dear gonhan!
First of all, thank you for your help.
I have two power module (https://www.ebay.com/itm/262102860958 ) with an mb102 bread board and i use it for powering my nrf24. I use a 7.5v 1000mA adapter to power the modules.
The capacitor is a 47uF one.
I power the two microcontrollers through USB connected to my laptop at the same time, because at this way i can switch the console output between the two controllers when i would like to see the output.

I try to follow the guides described here. All parts are from keyestudio except the two nrf24(with antenna) module.

I use the mysensors latest library , gatewayW5100mqttclient and a dht11 example sketch (but i have tried already another official mysensors lightsensor sketch) on the node.

Dear All!

Im beginner in the wireless sensor node + gateway world, and I started to build a simple MQTTClient Gateway (UNO R3 + W5100 + nrf24) with an DHT11 Sensor node (Arduino nano + DHT11 + nrf24).

The gateway and the node are seems to be working, but the node says that
"!TSM:FPAR:NO REPLY"

Could someone help me what might be the problem?
