here is my serial output. and remains like this.
i have found your sketch but can not seem to get it to work to gw 2.0

can you please print your code?
I am not so good to read the Message structure but it look like it present temperature and other stuff
-
Ah the gateway works fine with other sensors
The code for the pulse power meter is the one in the example

Yes you do, look at the last line and you will see it.

change SEND_FREQUENCY to 5000, upload to Arduino, when you see Received from GW, trig Digital Input 3 and after 5 seconds it should send data to DZ again

@asgardro
don't forget to use CODE function when posting code.If you don't see any reaction when you trig Digital 3 i don't know what can be the problem,
Have you tried another Arduino?
-
change bool pcReceived to false
-
ooops sorry about that... just found the function lol
the sensor inits itself once and then doesn't do anything/ i don't know through what miracle i got the pulse count.
will try another arduino... i do not think it is a radio problem..
thanks for your help
-
changed it to false.
put it true before to try to force the sensor sending independent of the count.. if i am correct
still the same outcome... will try tomorrow diffrent hardware
anyway, thanks a lot for the help
-
@asgardro said:
changed it to false.
put it true before to try to force the sensor sending independent of the count.. if i am correctYes it will but it will only send 0 to VAR in DZ so it will be a loop of same value.
Maybe that's why it never sends again.
Try now to trig digital 3
-
sorry for the next noob question but what do you mean by trigginh the pin 3? simulating the sensor? if yes i done that.. i have a led blinking
-
what have you connected to digital 3?
-
this is the code now

Do you mean LM393?
Can you put a flash light in front of the sensor so trigger it. You shall now see some text in serial monitor
-
@flopp
lm393
-
@asgardro said:
@flopp
lm393Have you trimmed the pot so the LED turns on when your power meter flash?
-
@flopp
i have done that and calibrated the lm393 , i have a blinking light that triggers the sensor. thats how i am testing...but after initializing sends the value first time and thats it
sorry to reply so late but have to wait 120seconds between posts lol

As the sketch starts by requesting the latest pulse count (e.g starting kWh value) and does not send anything without having received it, how do I "seed" this value to my GW? I am using a MQTT GW, can I construct a MQTT special message containing the value, or how is it supposed to work?
-
@maghac
I am using Domoticz ans MyS 1.5.1
You don't have to create VAR1, it will be created when you ask for it or it always exists for each Child.
If you want VAR1 to be exactly the same as your meter you need to open domoticz.db and set the value or in your sketch.
-
Anyone knows why I dont get the sleep() function (time) to work properly.
My hardware is EasyPCB, Pro Mini 3.3v 8mhz, Booster 2xAA and NRF24 radio.
My software is: standard sketch 2.0.1, with sleep function.The problem is the sleep time is 5 times less than declared so maybe timing?
When i enter sleep(10000) for example the nodes sleeps for 2 sec and wakes up.The interupt works fine.
My sollution was adding *5 to get the correct sleep time - but why doesnt it work?
-
@flopp I had to set pcReceived to true, upload the sketch, run it and then change back to false again and recompile/reupload. I can understand why it does it, since you don't want the pulse counter to reset to 0 if the sensor happens to restart (because you killed the power or whatever).
What I don't understand is how I can seed the value with the correct initial value.
Is it the controller (in my case HomeAssistant) or the gateway that is supplying the value?
-
It appears to be the controller that stores the value. I deleted the sensor from HomeAssistant and restarted, when it came back in again it started from zero.
-
This is a hack, but if using json persistence, you can set the count in the JSON file and restart home assistant, with the node turned off. Then turn on the node.
-
@martinhjelmare Yep, I figured I could do that. The absolute value is not so important actually, I'm more interested in the daily/weekly delta, which I hope Grafana can tell me.
-
is this the same sensor than the one in the guide?
http://uk.farnell.com/ams/tsl250r-lf/photodiode-sensor-l-volts/dp/1182346Can I also use also photoresistor? (Since I already have one)
-
@gohan - nope its not the same, and yes you can use a photoresistor (i have just made one) but I needed a transistor for it to work and also it had to be completley dark. Using this on batteries its much better using just a photoresistor because the sensor in the guide draws about 1mA which will drain the batteris very quickly.
I will post my sensor later.
Edit: this is the sensor i build:
The node (including pro mini) draws about 50uA sleeping and 170uA not sleeping.
The photoresistor was 5M ohm in complete dark.
-
The guide specifies LM393 Light Sensor or the tsl250r-lf so I thought it was the same since the same name.
Since the node will be powered with it's power supply, I don't have any battery drain problem in this case. But why did you use a transistor? Can't you just check for a threshold value in the analog input to count as a pulse?
-
Ok, all I can see is that it doesnt look the same at all.
@gohan - I tried, and I thought that should work - but for some reason I could not get it to trigger the interupt on the atmega
Looking the the voltage thresholds it was supposed to work but it didnt. I was thinking it was to low uA but i dont know really.
-
This is what I use togeheter with LM393

Instead of the 10k resistor, do you think I could use a potentiometer to "adjust" sensitivity? I would like to avoid messing up the readings with lights entering when opening the cabinet door where the meter is located
@flopp
Do you mind sharing your wiring? 940nm, isn't it infrared?
-
@gohan - a potentiometer is just a variable resistor so why not? Good idea if you have one laying around.
As i said before though, the try with the transistor is just a try - im not that good with transistors yet and dont know how they work exactly. After this i read somewhere that the base resistor should be bigger to protect the transistor... dont know how to calculate that.

Do you mind sharing your wiring? 940nm, isn't it infrared?I connected the photo resistor directly to the LM393.
I don't know if that is IR.

Hello,
First, thanks for this tutorial !
I used the code defined in tutorial but I have the following message for "void receive(const MyMessage &message)" :'MyMessage' does not name a typeDo you know what can be the cause of this error please ?
Thanks in advance for your help
-
@moumout31 do you have void receive(const MyMessage &message) somewhere in your code or where does it come from?
Could you post the full error message?Have you installed the MySensors library?
-
@mfalkvidd void receive(const MyMessage &message) is in the code.
MySensors library is installed, I already use it in other nodes.
It's strange because it works in another computer...The full error messages, in french beacause I'm french are :

-
@moumout31 My guess is that MyMessage is defined in your sketch, overriding the definition in the MySensors library. Could you post your sketch?
-
@mfalkvidd It's strange... It works with an older version of Arduino software... Thus, the problem is solved ! Thanks
-
Hello,
I don't understand why, but my power meter sensor gives a higher index than the real power meter index after 2 days.
I think that it counts more pulses than pulses provided by the power meter...
Does anybody encounter this problem ?
Can it be cause to bounce for example ?Thank you
-
@moumout31
could it be getting some light from another source?
-
@moumout31
I had same issue, check here for my solution
https://forum.mysensors.org/topic/4716/two-energy-meter/4
-
Hei.
How to connect arduino to electricity meter pulse out. Not to led.
-
@gohan No, the light is always switched off in this room and I tried, when I switch on the light, there is no pulse from the sensor.
@flopp Thanks for your help. What I see in your topic is that you increase from 10000µs to 40000µs the interval to avoid corrupted interrupts, is that correct ?
Thank you
-
@moumout31
Yes correct.
When I checked with Serial Monitor and some serial.print in different places I could see that arduino registered double interrupts
-
@flopp Thanks a lot, I will try this solution and check if it's better !
-
@flopp It seems to work, index on Domoticz is still consistent with the real index... I will see in a few days if it's still the case.
Thanks a lot for your help !
-
@flopp After a few days, I confirm you that the index is consistent with power meter index.
However, instant power in watt is not correcly calculated.
For example, when power meter indicates 550W, about 1500W is calculated by the sketch. Do you know how I can resolve this problem please ?Thanks a lot !
-
@moumout31
Watt calculation is using time between two interrupts.
How often do you send watt?
Did you measure watt with a measurement tool How did you get 500 watts from power meter?
When you send watt you need to measure exact same second otherwise it will not be correct.
-
@flopp Watt is sent every 20 seconds (as done in the original sketch).
500 watts is the power indicated on the screen of the power meter.
-
Just changed from 1-wire counter to MySensors for logging my power consumption. Using the same LED detector as I did when using 1-wire. Also changed watt limit to 20 000 (my heat pump likes to use 9-10kW sometimes). The wires from the old 1-wire net now provide power for the new MySensors-sensor. I have 10 000 led blinks per kWh. Had som crazy counter values with 1-wire that totally messed up the graphs and haven't seen anything like that with this sketch. Let's hope it stays that way.
Dumping data to Domoticz. This sensor gives me higher resolution as a bonus. The 1-wire counter was read every minute, this every 20-sec. 
My old 1-wire counter with one crazy value messing upp all the graphs:
I know that you can hold shift and click the value that is crazy to make the graphs show up good but you loose the data for the full day. That's not good.
-
I seem to be getting a connection to my gateway, while monitoring the two topics for the gateway i only seem to see any activity regarding this sensor on the gateway-out topic, and it keeps sending out a type 2 message (req). The serial monitor of the sensors is showing:

Is this a structural request message or is this the feature that requests the last known message from the gateway? Either way, there doesn't seem to be any sensor data being sent from the node to the gateway.

I dont know if I dont understand you, but it seems like your node is requesting the last pulse counter. I have mentioned this in several threads I have a problem with this (both this thread and rain sensor thread). Im using an ethernet gw and the request reaches the gw but there my error led blinks and it fails to send it back (or recieve it on the node) so it re-request it.
I have never been able to pinpoint it due to repeaters in between.
https://forum.mysensors.org/topic/2116/hard-to-grab-time-and-value-sent-from-controller/ (old).
-
@sundberg84 - You do understand me correctly :). I made a thread on the troubleshooting section of the forum for this simply because i suspected it was normal behaviour, however. It seems that the node isn't sending any other data to the gateway at all and it can not get the previous value as there isn't one. So, my post here and on the troubleshooting section was me aiming to get to this point and then troubleshoot the actual node to see what can be done to get it to send data.
-
Has anyone came across their pulse meter not sending the message for WATT, the other two messages are being sent perfectly fine. My WATT message has been working all day and suddenly stopped.
-
Make sure that you don't reach your wattage limit in the sketch.
-
@NiklasO - Where is this value stored? I've cleared the EEPROM and the MQTT topic too, but it still refuses to send the watt value.
-
@Samuel235
In the sketch, change this
#define MAX_WATT 10000 // Max watt value to report. This filetrs outliers.
I have it set to 20000, using 15 000 easily when it's cold outside. Just make sure that you use the right divider for your pulse/kWh count.
-
Ahh i see what it is it; its set to not send if it hasn't changed.... how much of a silly error that was from me. The wattage is way below 1000 but because i'm using a normal LED on another arduino flashing at a constant rate to set my node up, its not changing the watt value.
Back to solving my initial issue now >.<
Thank you.
-
Ah, I see. Well, I would like the sensor to send data even if it hasn't changed. What did you change?
-
Watt usage is normally changing all the time, so you should have data reported quite often
-
@gohan But Samuel235 had that problem?
Edit: well, ok, he had a different setup. I need to read better.
-
To be honest, i had it running for a while before it stopped sending the WATTS. But i'm guessing this is the issue as if i vary the blinks it sends it. I'de like to see if anyone has this working recently on OpenHAB through means of not touching the node sketch like people have posted before. I have an idea to send the data of the pulse count message onto the request message topic on MQTT and so then when it requests previous count it would have it.
-
This post is deleted!
-
EDIT:
This was not the case, I am still debugging the issue, in the mean time I have deleted the code.After some debugging it seems that Domoticz messes with the V_WATT and V_KWH, and the solution is to have two sensors, one for kWh and one for W.
After I changed it, I have consistent W and kWh.
See also this issue for Home Assistant
-
OK, I think I have nailed it. I am now running a beta code pulling S0 from my energy meter and I am getting consistent results.
Before when I checked the domoticz.db I got this for Energy:sqlite> select Name, sValue from DeviceStatus; Storage kWh|0.000;4773.700Now I get this:
sqlite> select Name, sValue from DeviceStatus; Storage kWh|118.000;11678062.000Notice that the first field is now with value, previously it was 0.000 (and I have updated the meter count to the actual value)
And in table Meter I now get consistent results:sqlite> SELECT Value, Usage, Date FROM Meter WHERE DeviceRowID=43; 11678003|1170|2017-07-22 09:25:00 11678012|1170|2017-07-22 09:30:00 11678021|1180|2017-07-22 09:35:00 11678031|1180|2017-07-22 09:40:00 11678043|1170|2017-07-22 09:45:00 11678053|1180|2017-07-22 09:50:00 11678062|1180|2017-07-22 09:55:00 11678072|1180|2017-07-22 10:00:00The field Usage is now populated as it should.
I will let the code run for a couple of days, then I will post the updated code here.

Here is a code example that works for me. I have an energy meter with S0 output and I use Domoticz as the controller.

One (probably stupid) question about the batter powered option: Since sensor cannot keep track of real time power usage as it sleeps most of the time, would it be possible to do the math on the controller side and get "5min delay real time power usage"?
By dividing number of pulses since last transmission, is that basically what this sensor is doing when not being powered by batteries?I could experiment with 2min delay f.eks, and see how batteries hold. If dht22 temp sensors works over a year with 5min transmission time, i hope 2min delay in pulse meter can hold 6mnt or something?
Another thing is that the electrical box is all metal, and there is a lot of electricity around the sensor so radio could struggle (I guess a repeater would definitively help)
-
Is it only me that is getting a compile error?
Error: call of overloaded 'set(volatile long unsigned int&)' is ambiguous
send(wattMsg.set(watt)); \ Send watt value to gwerror: call of overloaded 'set(volatile long unsigned int&)' is ambiguous

-
@gohan I get the same, both for 2.1.1 and 2.2.0-beta. Strange. I thought there were Jenkins tests that endured the examples compiled.
-
Replacing all
unsigned longwith
uint32_tmakes the sketch compile fine, but I don't know if that is the correct solution.
-
I created an issue for this, https://github.com/mysensors/MySensors/issues/910
-
The problem with "unsigned long" is that it can have different size based on platform it's compiled on.
Like @mfalkvidd says, use int32_t, uint32_t, int16_t and uint16_t which has a fixed width.
-
I was suspecting something like that, but I was not sure if changing variable type would affect something else
-
Ok, I got it working. On wemos it doesn't count pulses though. On domoticz does it have to configured as the value computed or from device? I'm asking because if you disconnect the sensor, on domoticz I keep seeing the same power reading
-
BTW, is there a way to have the pulse meter running on gateway? I got stuck because at startup it asks the controller the last count value and since the controller is not yet connected it just doesn't work.
-
@gohan for the first time use only the watt value....that time oldcounts will not bother.....
-
What do you mean? And how do I keep the count of the pulses if I don't get it from controller?
-
@hek is it me or the WATT readings are never sent? What could it be? Only V_VAR1 and V_KWH are sent.
-
@gohan How about
#define MY_TRANSPORT_WAIT_READY_MS 2000This will start up your code so you won't miss any pulses until controller is ready.
You may ask for the last known Value in presentation(), then it will be fetched as soon as the controller is really there after startup. This could/should be combined with a bool pcReceived, so you may decide to either add the value received from controller to the counts the node meassured in between or just use the received value (starting from second time value is received from controller).
-
That actually is not that critical, as I am going to move to MQTT and that should be working anyway. Right now it is working on a UNO with NRF24, but my biggest issue is the WATT reading that it is missing
-
Any more suggestions on the Watt issue?
-
Did you by any chance change SLEEP_MODE to true?
-
No, I get every pulse reported as soon as it is detected.
-
I think I found a problem: the WATT calculation is returning values over 172000 watts and since I put 10000 as the max value, it was not sending anything. I double checked my energy meter and indeed it is 1000 pulses per KWH and this is what I set in sketch
-
@hek I said I found the problem, I didn't say I know how to solve it

-
Please post you sketch.
-
it is the one in https://www.mysensors.org/build/pulse_power
-
How is the pulse counter set up? Is it connected to the S0 port?
Edit:
If you are using S0 it is vital that you use a pull down resistor, if you dont’t have that you get false pulses.
-
I'm using the lm393 light detector. Domoticz is able to do a calculation from the pulses to give a Watt value and it is correct but it does it every 5 minutes and it is too slow for me
-
@gohan - is Domoticz updating anything (except switches) faster than 5 min? I dont think so...
-
If you send the watt reading faster it updates like the switch, anyway I need the watt values for node-red also
-
Could it be the Light sensor is triggering more interrupts from each pulse?
-
Hi Niklas,
I know this is a very old post, but its worth a try. How did you get out the daily Kwh usage? As default my sensor only gives Watts and Kwh (accumulated from start), I have tried to run a Scene in Vera UI7 where there are a function in the sensor called resetKWh(), but it looks like it doesn't do anything. Any tips would be great, thanks.
Henning
