Hi All
Using 3.4 and having issues reading temp/humidty
My sonoff sensor is configured as so:
My MQTT Thing has:
And the Channel has this value, which is very old/wrong (Actual sonof shows humidity 51% for example)
May someone point me in the right direction?
Thanks!
You have two times the same screenshot but missing the thing definition.
Can you share your thing definition(copy and paste from the code tab instead of doing a screenshot)?
Also if I would be you: I would connect to mqtt with a3rd party tool, e.g. mqtt explorer, to validate topic name and what’s really send from sonoff to mqtt, so that you know if the issue is with sonoff or OH
Sorry! apologies

The power topic (working as per your headline) has
stat/subfloortemp/POWER
as a topic, but humidity and temp have a different topic.
I’m not familiar with sonoff but I would try e.g.
stat/subfloortemp/HUMIDITY
as a topic.
Without knowing what data is really published from your device to mqtt, it’s hard to help. Therefore still recommending to verify published mqtt messages with another tool before configuring your thing
Thanks and sorry updating the topic name is under the item?
It’s within the thing configuration you have posted before. Have a look at the “stateTopic” records
But that’s just a guess, as all state topics normally have the same pattern.
Without knowing what’s really send by your device, it’s hard to help
Under logging on the device do you have a value for the Telemetry period because if it doesn’t send anything you won’t see any values.
Yes, 300. And the state topics are correct I believe.
I have a TH16 but my json path is:
JSONPATH:$.SI7021.Humidity
What does you tele topic look like?
What does the tele topic look like on the device console?

Mine looks similar:

Here is my setup so you can compare.

Mine is working.
Yep its the same, I just recreated the MQTT thing, same issue. The sensor is working because the values on the sonoff console are correct
Ive got another in my ceiling that has the same configuration, it too works
This must be a Openhab bug
If it was a bug then no MQTT would work and your other devices wouldn’t work either.
Maybe remove the % in the unit measurement for humidity
The only difference I have is I don’t bother with password for my mqtt. But if that were the case the power switch would not work either.
Other than that is looks like it “should” work.
Are there any message in OH log?
Is your item constantly showing the same wrong value → not updating at all OR randomly showing different values, but updating?
Your humidity item is number:temperature - as humidity is % and not °C I would choose number: dimensionless as type.
Edit: plain ol number seems to have fixed it! Thankyou!
