Automations failing to set temperature

[kp-bit]

Description

I've been using 1.7.0 for a while, but it suddenly stopped working. Upgraded to 1.8.0-Beta-14 which at least was able to talk to both the TRVs and Better Thermostat UI.

After upgrading it get these errors, and can't seem to find any documentation on changed syntax:
The automation "Target Temperature Home" (automation.target_temperature_home) has an unknown action: better_thermostat.set_temp_target_temperature

Steps to Reproduce

1. Use better_thermostat.set_temp_target_temperature to set TRV temperature

Expected behavior:

Temperature change.

Actual behavior:

Error is thrown.

Versions and HW

Home Assistant: 2026.3.1
Better Thermostat: 1.8.0-Beta-14

TRV(s): Danfoss Ally eTRV0103

Yes the available "BT Extension" also fails to handle "temperature set" with this error. We need a routine that change the presets for BT now. So i wrote a simple automation with scheduler card and proximity on my own.

[KartoffelToby]

Version 1.7.0 is too old for HA 2026.3, pls checkout the 1.8.0 Beta, it will be released soon

[kp-bit]

@KartoffelToby that's exactly what I'm doing, but commands like better_thermostat.set_temp_target_temperature doesn't work. Are there any (undocumented) changes in 1.8.0 or is this a bug?

[KartoffelToby]

@kp-bit you can think of 1.8 as a complete rewrite,
So yes it shoud be Work in 1.8

[Yasounet]

Also ran into the same issue.
BT: 1.8.0-beta16
HA 2026.4.1

Services that were previously used for automation are no longer valid:

BT only announces following services:

Let me know if you need any additional digging.

[cl445]

In the 1.8 rewrite the custom better_thermostat.set_temp_target_temperature service was removed. Better Thermostat now exposes a standard climate entity, so automations should call the built-in climate.set_temperature service targeting your climate.bt_* entity instead of the old BT-specific service.

The only services 1.8 still provides are run_valve_maintenance, reset_heating_power and reset_pid_learnings.

Could you switch the automation to climate.set_temperature (target: your BT climate entity) and confirm it works? Then we can close this.

[Yasounet]

Using climate.set_temperature doesnt seem to be directly replacement, as this no longer allows you to restore previous setpoint (well, at least not in a simple way that was possible previously). Also if the previous behaviour will not be restored, docs at https://better-thermostat.org/deep-explanations/schedule-and-night-mode/ should probably be updated to reflect that.

In the meantime I'd advise people trying to mirror previous functionality to just use climate.set_preset_mode to set either eco (19) or sleep (18) instead of bt.set_temp_target_temperature, and climate.set_preset_mode None instead of bt.restore_saved_target_temperature. While values in the presets are hardcoded, its still the easiest drop in replacement for your automation in 1.8+
