Are you changing the setpoint on the TRV Controller controlling the Stella-Z, the Stella-Z itself or the Remote Stat? :?

OK, thanks - I haven't got an instant answer; I will try and find time to investigate the issue tomorrow. :)

Re: TRV Controller Discussion Thread

Hi Keith,
I need to see a device definition print for the remote stat.
Can you execute the following command from the Indigo Scripting Shell (see bottom of the Indigo plugin menu):
Code: Select all
indigo.server.log(u"Remote Stat Device:\n {}".format(indigo.devices[12345678])
where 12345678 is the Indigo device Id of your remote stat device i.e. not the TRV Thermostat Controller. The output is written to the Indigo log if you could copy and paste it in a reply. :)

Re: TRV Controller Discussion Thread

Better now! :)

1) Without remote stat device specified - thermostat settings (including from UI and schedules) works but seeing
" TRV Error TRV Controller can't control TRV 'new device 2' as the TRV doesn't report temperature and there is no Remote Stat defined!"

2) When specifying remote stat device - it works OK (temperature is shown correctly), but theTF021 setpoint is always 5C - even in case I'm changing it, immediately reset by the TRV

I.e. no schedules or manual settings works

Some small error in the logic somewhere :)

What setpoint are you changing: I need to know whether you are adjusting the physical device or an Indigo device and which one? :)

Re: TRV Controller Discussion Thread

Actually, tried everything, including TRV device delete and create.

1) Physical device (physical buttons) - resetting back to 5C in a few seconds ( Z-Wave sent "Conservatory HeatIT Thermostat" change heat setpoint to 5.0°)
2) Physical device via Indigo UI - resetting back to 5C in a few seconds ( Z-Wave sent "Conservatory HeatIT Thermostat" change heat setpoint to 5.0°)
3) TRV device - adjusting the temperature but physical device is not syncing / staying at 5C

Only happens when the "remote stat" is specified.

Re: TRV Controller Discussion Thread

Have you got Remote Setpoint Heat Adjustment enabled in the TRV Controller device settings?

What are you setting the setpoint to?

Re: TRV Controller Discussion Thread

No adjustment enabled

Any setpoint - tried 19, 20, 25, etc... Identical outcome - resetting back to 5C

Re: TRV Controller Discussion Thread

In the previous image your Air sensor (which is the remote stat?) is showing 26 deg C which I think is why it is setting the temp to 5 deg C i.e. effectively off.
It is more than 21 deg C. Is the 26 deg C correct?

Re: TRV Controller Discussion Thread

Tried to set 32C - the same issue, resetting to 5C :)

Is it possible to add a setting to be able to switch on / off the setpoint logic? For a smart floor thermostat - only schedules (with setpoints) are required. TF021 will automatically do the rest. However, the logic could be very useful in case of a "dumb" relay controlling underfloor heating - so it would be nice to make it configurable.
