what are the arguments given to ebusd? maybe --mqttjson is missing?

[wiedwo]

ebusd --foreground --mqtthost=core-mosquitto --mqttport=1883 --mqttuser=addons --mqttpass=Noh3ahth2helo5AoX7CheRiaFoo8in7uv1ohyeiphaith6ohquiedaewookie4Ai --scanconfig --mqttjson --configpath=/config/ebusd-configuration/ochsner/1524849 --latency=40 --accesslevel=* --pollinterval=10 --mqttint=/config/ebusd-configuration/mqtt-hassio.cfg --mqttvar="filter-name=" --mqtttopic=ebusd --device=ens:192.168.178.68:9999 --log=all:info

[john30]

seems to be some issue with HA not providing the message value as "value_json" variable. did you change the mqtt-hassio.cfg file? or somehow disable mqtt json support in HA?

[john30]

if this is still an issue, then please post here the value actually sent to HA in the MQTT integration for the global/updatecheck topic

[AlexandreA74]

I have the same issue on a new installation, with an adapter I ordered last year.

Should I update the firmware of the adapter ? I was thinking it would not matter, it was working fine in the past, and this warning started to come a few months ago. I had to reinstall everything for other reasons.

[john30]

again the question if --mqttjson was passed to ebusd as I doubt that

[AlexandreA74]

Yes, ebusd runs with the --mqttjson option set

[john30]

and was the updatecheck topic last pushed to recently, i.e. with the mqttjson set?

[AlexandreA74]

I'm running 20231015 on the adapter - would updating it help ?

[john30]

I don't think so. it anyway depends on when the message was last received, so please just check in HA when the last message was received. i suspect that to be too old

[AlexandreA74]

You are right: the message is not appearing anymore.
