Thermostat HC1: can not set mode to OFF

[bartplessers]

PROBLEM DESCRIPTION

Recently I updated to EMS-ESP Version 3.6.4 I noticed that my home assistant automation to turn my heating system OFF does not work anymore. Sample automation:

alias: Verwarming uit
description: ""
trigger:
  - platform: time
    at: "23:00:00"
condition: []
action:
  - device_id: fc7d3adde5ddb3170b13319aaae53729
    domain: climate
    entity_id: climate.thermostat_hc1
    type: set_hvac_mode
    hvac_mode: "off"
mode: single

HARDWARE: BUDERUS Logamax PlusGB192iT40 - boiler BUDERUS RC310 - thermostat BUDERUS KM100 - gateway

Problem is that I can only change mode to auto or heating, but in both modes, the circulation pump keeps running (+/- 30W continiously)

To save some power, I want to set my system OFF with ems-esp

EXPECTED BEHAVIOUR

The RC310 does not have a off-mode, or we don't know how to set it. In #1398 we've learned that the newer BC400 have a off mode , but this works not for the RC3xx thermostats. So mode setting for RC3xx is unchanged, only manual/auto and off not working.

@bartplessers you said "I noticed that my home assistant automation to turn my heating system OFF does not work anymore."

did it work before? in which version of EMS-ESP?

[bartplessers]

I have to dig further into this. Indeed, before upgrade, I can see following:

At 00:15, temperature is set from 21 C to 13 C. (1) This is done by ANOTHER automation. Result is that

• boiler stops working (2)
• circulation pump stops working (3)

this is OK.

But normally my automation to turn OFF the boiler should have been running at 23:00, but I can't see any change in behavior at that time. This is an indication that at that specific day (2023-05-06)

• that automation did not run, OR
• the OFF command did not have any influence

so maybe I'm wrong on this.

I will dig further into my logs to see if the OFF command worked befor.

kind regards, bartplessers

Maybe this was at higher outdoor temperatures and the reduce mode changes from switch off to reduce.
