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

this is the code now

@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?

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.
