Pulse Powermeter

[Francois]

Hi I just complete and compile the pulse power-meter on lib 1.4.1 and I don't get any values back from the sensor. The pulse sensor is wire as per the instruction what can the problem be here?

Here is the info from the serial port:

send: 21-21-0-0 s=255,c=3,t=11,pt=0,l=12,sg=0,st=ok:Energy Meter
send: 21-21-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0

I seem to have the same problem. Did you find any answer to this?
I get this reply from the serialmonitor:

Looks like the sensor is requesting last known pulse count from the controller. Do you have anything answering this request?

[Øyvind A. Espnes]

No. Where do i insert this?

[hek]

What controller are you using?

[Øyvind A. Espnes]

Domoticz

[hek]

Sorry, I'm not using Domoticz myself... So I'm not sure where you fill in your pulse count in the GUI (VAR1). You should probably also check that Domoticz support requesting of VAR1-5.

[Øyvind A. Espnes]

Ok, so the sensor is requesting a number to continue the count? And there is no way to bay-pass this and insert my own?

[hek]

Yes, you could hard-code the current pulsecount in the sketch. But then it will revert back to this value every time the sensor loses power and restart.

[Moshe Livne]

@hek You can't access these from the UI. He would have to write a sketch that sets this var. Not big deal but awkward. would have been nice if the VAR1-5 could be accessed.

[Sweebee]

You could also save the value every time in the eeprom, so when the sensor loses power it can recover the value.

[TommySharp]

Would it not be the MySensors gateway that should respond with the last pulse count?

[epierre]

@Tommy-Sharp the gateway is like the RFXTRX, it has no memory by design.
