#How do I get better support for Bosch Radiator Thermostat II on ZHA?

I have bought these thermostats that are working with Zigbee.
Unfortunately they're missing several pieces of data in ZHA, which is supported in Z2M.
Is there a way to get better support or contribute it? I've seen these things called quirks, but I'm not sure they apply.

But is that the only solution? Quirks are described as a way to deal with off-spec devices, but if anyone is going to follow specs, it's Bosch I imagine.

#

So it feels like it's something central to zigpy that's not done?

I'd still start there. ZHA is now under the zigpy org on github as a separate lib so very closely related to quirks. @urban minnow maybe be able to add more to it when he gets a chance.

I pinged dmulcahey as he would know if it needs a quirk or some other change in ZHA as the OP thinks

meant to ping the op. sorry bout that...

Spec compliant devices just work

I know one device that's never worked correct. Annoying, and I have no skills to fix it.

#

The current 'pro' version of the Aqara cube has about 2/3 of it's actual functions. It was just added to the quirk list of the old cube and lots of stuf just doesn't work right.

#

I've had an issue in since years now but don't know how to help with the issue.

Just got back to this. It looks like there's already a request in place to get full support: https://github.com/zigpy/zha-device-handlers/issues/2476
When I look in my overview, I see what the image shows. Compared to Z2M which has all these parts:

climate (local_temperature, local_temperature_calibration, occupied_heating_setpoint, system_mode, pi_heating_demand, running_state), battery, operating_mode, window_detection, boost_heating, remote_temperature, setpoint_change_source, child_lock, display_ontime, display_brightness, display_orientation, displayed_temperature, valve_adapt_status, valve_adapt_process, linkquality
Notably I don't have the window detection which I was interested in, but there are more that are just missing seemingly.
I also can't control it, I just get the following error:
Failed to perform the action climate/set_hvac_mode. Failed to write attribute system_mode=<SystemMode.Off: 0>: <Status.INVALID_VALUE: 135>

Unrelated to this, but I've also had another smart switch that was listed as not working with ZHA, but working with Z2M/Deconz.

I'd be happy to contribute with support for the devices, I just want to be sure it's done correct. Quirks seems like more of a workaround to me, but maybe that's not the case?

Depends on the function

#

I’m at soccer practice with my son. Open an issue for the plug on the quirks repo or add to existing ones. We can start there and figure out what is needed

#

Sounds good, I apprecaite the help, I'll try and do that, and like I said, I'm happy to provide help if needed.

#

I did notice that Z2M has this in the info on the device:

The system_mode exposed by the device according to zigbee specification is always 'heat'. To set or read the actual operation mode of the device, use the manufacturer-specific feature 'operating mode' (see below)
So it might just be that the extra features are out of spec I guess.

#

I'll make that post, don't worry about responding now.
