Sonoff TRVZB External Temperature Sensor Calibration

hi Peter. none of the 10 TRVZBs I am using here ever go ‘off’ by accident.
check when it happened in HA… then check HA for logbook. maybe that will give you a clue. someone toucing it? use the childlock-on. etc.

103

I’m using the latest Blueprint with Sonoff TVRs also installed with ZHA and having the same issue.
I managed it by selecting a different temp sensor, and then updating automation in YAML putting the correct entity in.
I’ve done this now for all of the TVRs I can and it’s working perfectly, it’s just the filtering that isn’t right for some reason.

104

that sound like a different issue: You have the sensor not showing up?
(mrchips says it was the trvzb not showing up in the filter… although the pic is not clear on that.))

filtering for sensor is:

          filter:
            - domain:
                - sensor
              device_class:
                - temperature

So your external sensor is probably not classified as proper temperature sensor or not even as sensor… pls check.
you can always remove the device class filter, but that might give you a very large list of sensors.

I was trying to use blueprint v1.0.1
I’ve moved on though and have it all working ok via Better Thermostat

106

funny: I just moved away from better thermostat as it is an additional layer around and always yield issues when restarting HA.

107

Interesting.
What did you move to?
I might end up swapping to Versatile Thermostat in the future (due to the more extensive documentation)

108

Highly recommended if you use a Sonoff TRVZB. I’ve been using Versatile with my TRVZBs for a while now and am very satisfied.
Direct valve control with Versatile Thermostat (VT) is the major technical advantage over many other solutions because it actually regulates the opening degree of the TRVZB – rather than just setting the heating to “on/off” or a target temperature.
There are a few other things about Versatile that are very convincing, but the possibility of direct valve control was and is the main argument for me.

Thanks, think I’ll start trialling VT instead :+1:

Agreed. I use VT for the same reasons. Dev seems to be adding new features regularly too. :+1:t2:
