[Device Support Request] Full implementation of BOSCH Radiator Thermostat II (BTH-RA)

[dierochade]

Problem description

I use skyconnect+zha.
I am able to pair the device using zha.permit with install code and source-ieee.

It then shows up with 4 entitys:

(screenshot below)

1. [button.bosch_rbsh_trv0_zb_eu_identify]

    BOSCH RBSH-TRV0-ZB-EU Identify
    unknown	device_class: identify
    friendly_name: BOSCH RBSH-TRV0-ZB-EU Identify
   

2. [climate.bosch_rbsh_trv0_zb_eu_thermostat]

    BOSCH RBSH-TRV0-ZB-EU Thermostat
    heat	hvac_modes: off, heat
    min_temp: 5
    max_temp: 30
    current_temperature: 24.6
    temperature: 21
    system_mode: [<SystemMode.Heat: 4>]/heat
    occupied_cooling_setpoint: 2300
    occupied_heating_setpoint: 2100
    friendly_name: BOSCH RBSH-TRV0-ZB-EU Thermostat
    supported_features: 1
   

3. [sensor.bosch_rbsh_trv0_zb_eu_battery]

    BOSCH RBSH-TRV0-ZB-EU Battery
    100	state_class: measurement
    battery_voltage: 3.1
    unit_of_measurement: %
    device_class: battery
    friendly_name: BOSCH RBSH-TRV0-ZB-EU Battery
   

4. [sensor.bosch_rbsh_trv0_zb_eu_hvac_action]

    BOSCH RBSH-TRV0-ZB-EU HVAC action
    unknown	friendly_name: BOSCH RBSH-TRV0-ZB-EU HVAC action
   

I have got two main issues:

1. The state of climate.bosch entity is always "heating". If I change the target temparature I can hear the motor of the device closing/opening the valve, but it doesnt change the state.
   If I do set the state manually in the developer tools, it changes but switches back after some seconds.
   Besides, the HVAC action (entity 4) is shown as "unknown" all the time.

2. Most attributes are missing

From the integration via z2m it is known that there are many more attributes, some are importat/useful:

window open, boost, position of the valve, temperature offset, disabling of internal temp sensor, many more ++

As far as I understand, these attributes can be manipulated via a set command in z2m....

Additional wish

The device got a nice led color ring that can show status. I do not know if the led can be manipulated or is controlled locally by the device solely?

After finally switching to a SkyConnect, I want to ditch my Bosch SHC but without a working quirk, I cannot fully control the thermostat.

Please prioritize this. If needed, I might be able to provide neccessary information about the device.

[Samueras]

Same from me, If Information are neede, I'm happy to help, for the Bosh Thermostat 2 and the BOSCH Smart Home Roomthermostat

[JohndeWaal]

I tried to connect the BOSCH Radiator Thermostat II today. On multiple attempts it connects each time, but most times without any entities. It only connected once with entities (battery 100% HVAC), but they didn't work.

[Samueras]

It worked for me. What you do is first you use the zha.permit zu give it the adress and installcode that is inside the battery lid. That you need to go in HA to adding new Zigbee devices. Then you reset the Themostat. (Hold the button while insterting the batteries till it blinks orrange.) Lastly press the button ont the thermostat once more so it enters pairing mode.

Did this each time. I’ve got 53 working zigbee devices, but this one isn’t working. I bought it to replace a Tuya thermostat, even that worked okay (only battery drained every 2 months).
I ordered a Bosch controller now, hope it works with Home Assistant.

I actually want to move awy from bosh for the don't hold the Set temperatur but hat up and cool down for about 2 degree all the time

[ulrichkamp61]

they don't hold the Set temperatur but hat up and cool down for about 2 degree all the time

Same for me, it only holds the temperature, when I frequently update the Set temperature, which is Occupied heating setpoint.

Also, the Z2MTT dialog says for element Remote temperature -> Setting this will disable the internal temperature sensor until batteries are removed!, which is not right. I can always change the Remote temperature, and as far as I understood, this setting interferes with the heating mode and with the Set temperature. But I do not yet understand the behavior fully.

With some tricks (setting up the thermostat target values about every 30 minutes reflecting the room temperature as needed) I got the thermostat working for me, but it is not very handy and intuitive.

So, it seems there are some small bugs in the Bosch Thermostat Z2MTT implementation. I also could help with screenshots, experiences and I can support with testing.

@Samueras @ulrichkamp61 @EverybodyElse

Regarding the overshooting temperature: I believe this is intentional, to compensate that close to the heater the temp will rise very fast but not in the rest of the room. I have some trv's with external sensors that do not show this kind of wave overshooting the limit set.

regarding the remote temp: As far as i can see, home assistant tracks "remote" and "current" temperature, but it is the same value all the time. So current is just mirroring remote values. I have not tried to deactivate the remote temp (because it will just keep the last state forever till reboot of home assistant), but it might end in mirroring an unavailable state - and the documentation on z2m means you have to reset the trv to enable local measurement again?

I run these trvs on z2m now, which works as expected. But there is major setback in my installation: The device (without hub) has a build in schedule that cannot be wiped (as i do not know how, at least). this would be annoying but could be overcome with a simple time based automation. but it calls this in-device temperature target also every time when switched to auto mode… This has nothing to do with zigbee but the firmware itself.
I was able to fix this in node red, but it is a real pain…

For any one interested, I made a rather big flow in node red (based on z2m) with this key capabilities:

• workaround to overwrite built in target temps schedule of the device
• run different schedules for workday and holiday (ha integration) with a 15 min schedule (manual timetables with array of targettemps though)
• ability to change temperatures (triggered by external event/manual switch) specified trv and time(range), e.g. heat now for x hours, -heat guest room today, heat living room this evening etc
• block schedule for single trv after manual change for a given period of time (e.g. 90 min) to prevent imminent overwrite.
• boost functionality up to 30 mins (6*5 min)
• away mode
• window sensor
• external temp sensor
• display brightness auto dim at night
• lovelace interface (incomplete, cause i still think how to best use the ability to change temperatures)

I would be interested in collaboration and further joint development, although it is still work in progress and documentation limited..just pm me

[jclsn]

Here is all the relevant information I could gather. Maybe OTA would also be relevant for updates, but the endpoint is quite complicated.

I will start writing a quirk this week. This thermostat deserves full support!

Interesting! I don't have this issue. My heating setpoint is at 21°C and it stops at 21°C.

What is your value for ctrl_sequence_of_oper ?

[coxtor]

I've just purchased three bosch thermostats and was able to pair them using the QR-Code with ZHA. However I only have a couple of sensors there: temperature, mode (heat an off) , hvac(unknown) and battery. LQI and RSSI are not available.
There should be a whole bunch more or am I wrong?

[jclsn]

@coxtor Yes, I am currently writing a quirk to support it. It should be ready in the coming weeks. This thermostat actually supports even valve opening from 1-100%. Really nice!

[BernhardMaier]

@jclsn Very good 👏 I'm really looking forward to being able to use more functionalities.

You just became my personal Hero.
