Implementation of thermostat and WindowCovering in a bridgedDevice

[elausys]

Hi,

I'm trying to create a bridgedDevice which includes different type of devices. It works well for some of the device types but I'm facing an issue to implement the thermostat and WindowCovering devices.

See below the source code and resulting error. Could you help me to identify what could be the reason or provide an example of configuration for these types of devices ?

Thermstat device :

Error :

WindowCovering device :

Error :

Thank you very much for your support !

Hi @elausys. The error messages are cryptic here but the "conformance" expressions indicate the problem...

Matter conformance defines what you can do based on the features enabled on a cluster... So for example, for the thermostat cluster you need to enable Cooling and Heating features to use CoolingAndHeating for controlSequenceOfOperation. Conformance expression [HEAT & COOL] is saying CoolingAndHeating is allowed only if both cooling and heating are enabled.

For matter.js you can enable features using with on the behavior classes. So e.g.:

    ThermostatRequirements.ThermostatServer.with("Heating", "Cooling")

This enables the implementation in matter.js. Then CoolingAndHeating is legal for controlSequenceOfOperations.

BTW if you want to avoid the constant "4" you can use matter.js's enum definition Thermostat.ControlSequenceOfOperation.CoolingAndHeating.

The window covering error is similar... It's saying you can't have a shutter unless you enable Lift or Tilt features.

I am also trying something similar; trying to bridge lennox wifi thermostat and airthings wave air quality sensor .. but i just started today with almost zero clue, It would be a great help if you can share your code/example .. thanks. -g

@singh-io Please check the post, seems all images are broken ... and honestly ... please post better "test" than images for code or error message because would be simply better readable

I just replied to the original post sad 😢, was looking for some help. and surprisingly I can still see the images while writing this response, so it's not so easy to 'test', seems the GitHub markup is broken at multiple places.

@singh-io Please share images with errors or code. I am also working with bridged devices which includes thermostat and window covering. I can help you.

Can you point me to some examples for creating a bridged device?

There's a bridge example here:
