[shelly] Some channels on Shelly Pro 3EM report NULL

[hoinmic]

The Shelly Pro 3EM device does not display all values, some channels display " NULL ". The debug functionality of the shelly addon shows the arrival of the corresponding data, but the channel are not updated.

Tested with the commits on the openhab-addons branch 4.2.0~M2-1

I have not yet discovered any errors in the shelly folder of the openhab-addons repository.

Does anyone have an idea what is wrong here?

Addendum:
It is noticeable that even with the UI (openhab+openhab-addons version 4.2.0~M2-1) for the Thing, only the channels

shelly:shellypro3em:pvInverter:meter1#currentWatts
shelly:shellypro3em:pvInverter:meter1#returnedKWH
shelly:shellypro3em:pvInverter:meter1#voltage
shelly:shellypro3em:pvInverter:meter1#current
shelly:shellypro3em:pvInverter:meter1#powerFactor

are suggested (for all three electricity meters). From the channels

channel="shelly:shellypro3em:pvInverter:meter1#totalKWH"
shelly:shellypro3em:pvInverter:meter1#reactiveWatts"

every trace is missing.

Addendum:
I have now compiled the latest version of shelly openhab-addon from mainbranch . It seems that the BaseHandler receives all data.

But still no output on the channels.

Something you can look into @markus7017 ?

Please switch to the latest DEV build and try again, check READMEbeta

Note: The DEV build is always newer than the version in the official Distro or Milestone builds. Current development is based on 4.1-SNAPSHOT, 4.0.x and 3.4.x might be outdated.

Hi Markus

I have implemented your solution. Unfortunately without success, the behaviour is still the same. The two channels "totalKWH" and "reactiveWatts" are missing.

I have done the following:

wget -O org.openhab.binding.shelly-4.2.0-SNAPSHOT.jar https://github.com/markus7017/myfiles/blob/master/shelly/org.openhab.binding.shelly-4.2.0-SNAPSHOT.jar?raw=true  

# -> removed all shelly things

# -> Uninstall Shelly binding form UI
openhab-cli console   -> feature:install openhab-transport-coap

systemctl stop openhab.service
sudo cp org.openhab.binding.shelly-4.2.0-SNAPSHOT.jar  /usr/share/openhab/addons
systemctl start openhab.service

openhab-cli console   -> bundle:list

added shelly pro 3em thing
