Power sensors stopped working

[jocke4u]

Hi,

I have 3 power sensors running (total, house heater and water heater). They have been working for a long time.
Last weekend I had a power outage and they stopped working.
Other sensors works.

Watching in MYSController and power sensors reports V_VAR1 but message is empty.

Any idea why?

[gohan]

Did you try to reflash them? Did you try to do a debug to see if they are actually measuring something?

[chorob]

@jocke4u could you share some more information on your power sensors? Pictures and sketch? I am trying to replace my ubiquiti mfi setup and power sensors are my last sensors to go. Thanks!

[gohan]

@chorob I got a sonoff pow and some gewiss material to make a similar unifi mfi, but I only have one relay

[jocke4u]

I have been debugging a bit now and the sensor receives pulses but the issue seems to be that it doesn't receive the old pulse count from GW (Ethernet) and therefore doesn't send the values.

I have upgraded the GW to 2.1.1 and with the sketch below

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

Do I need to have any other implementation to save pulses?

The Sketch for the energy meter looks like below (currently some extra printout's):

[gohan]

Then it could be the controller not responding to requests for value?

[jocke4u]

I guess so - using openHAB 2.2.0 stable and quite late snapshot mysensors-binding for 2.2.0.
Maybe @TimO have an idea?

[gohan]

I remember another post about Openhab not responding to requests not long ago, maybe it is related

[sundberg84]

@gohan - I have had this issue in Domoticz as well several times. A nod requestiong a V_Var1 can sometimes takes up to 30 min to get a response and I think its something to do with timing and/or repeaters in the response. It seems like Domoticz is answering. That was the main reason i build my logger to debug this but so far I have not encountered it again.

[gohan]

@sundberg84 said in Power sensors stopped working:

30 min

That is quite a lot of time

[sundberg84]

@gohan in my mind and without any evidence its like the request comes fine to the gw, responded by domoticz but the answer from the gw and back to the node gets lost through the repeater... I dont know this for sure though!

[gohan]

without repeater it works better then?

[sundberg84]

Without any evidence - yes. I have not made that much tests yet since I waited for my logger. I have made some posts about this on the forum. I dont want to make any conclusions yet. @gohan
