Temperature minimum in Wiser HA monitor?

[guru-gubbins]

Firstly, many thanks for a brilliant Wiser integration into HA which I use every day.
I have recently been testing the use of a spare radiator TRV and room monitor thermostat to monitor (not control) the temperatures in some outbuildings. Although the temperatures read accurately within the android Wiser app, the readings displayed within Home Assistant don't change below 5C. Has an arbitrary minimum been set in the HA integration? And can this be changed to say -10C ?
Many thanks

found it, the HA Wiser component uses a seperate library to talk to the hub (https://github.com/msp1974/wiserHeatAPIv2/blob/master/wiserHeatAPIv2), within the const.py file we set a min to 5C

@msp1974 Any reason why we set 5C? I remember doing it but cant remember why.. I know when a valve is closed Wiser sets the target temp to somerthing really low (-30 i think).. Could we set the temp to 0

Also guru, from my experience the wiser trvs arent the best temperature sensors.. if you are using it to monitor, not control, outbuildings then Id recommend Sonoff or Aqara sensors instead much better and offer humidity pressure etc.

I'll gladly buy your valves of you :-)

I know this is the minimum you can set a valve target temp to.  I may have assumed this is also the min temp they will report.  If set to off, the target temp is set to -20c, but you cannot set it to anything in-between that and 5c.As you say, we will need to amend the api temp validation function to allow for reported current temp to be below this.Will do for next release.

Many thanks for the very prompt and supportive replies. I realise that the TRV's may not be the most accurate but was testing them when I found, to my cost, that the Ubibot WS-1 temp/humidity detectors can't cope with humidity!!!!! So I'm using the Wiser stuff to test alternatives.
By the way - the Wiser Room Thermostat also measures humidity but this doesn't show on the Wiser app, only on the screen. Is there any possibility of this being available via HA?
And another pat on the back for your Wiser HA implementation. Went for a sunny walk this morning, set Wiser to away mode. When I got back home, the Wise android app (yet again!!) required me to first log-in - a complete pain. But not the HA implementation - switched back on straight away. Great stuff guys :-) Thanks again.

I think humidity is in the attributes of the TRV, I can check later I use Sonoff & Aqara Temp/Humidity devices I think they are more accurate

Further observation. The room thermostat was again in the greenhouse last night, temperature down to <2C via Wiser app but again only 5C via HA. But, even though the heating schedule was completely disabled, the unit was sending heat demand signals to the hub. So there must be an anti-freeze overide setting which kicks in below 5C, regardless. This is probably why you set the limit to 5C.
So neither the TRV or room monitor are any use for my "winter outhouse monitoring" - but having humidity readout from the room monitor (or TRVs if possible) via HA would be nice.
Cheers

@guru-gubbins You can display the humidity in HA by adding the climate entity for a room thermostat to an entity card like below.

I don't believe a TRV has the Current humidity attribute so this is only possible with a roomstat.

Ah, many thanks. I hadn't spotted that.
Much obliged.

leaving this open for now, as i'll add it to the recipies tonight

[msp1974]

should be fixed in v3.0.23 to no longer limit min current temp to 5C.
