Target temperature changing at random

[kbunto]

Disclaimer: My first bug report, will updated with other information if I missed the mark here. May also be resolved if anyone know where I can find the trigger for target temperature changes in BT.

Description

Target temperature changing to 30 deg. C at seemingly random times. Strangely it only happens for one of two SRTS-A01 in my better thermostat setup.

Steps to Reproduce

Unknown, happens rarely and I have not found a pattern.

Expected behavior:

Target temperature to stay where it should.

Actual behavior:

Target temperature changes at seemingly random times to 30 deg. C.

Versions
