Adds support for the Bosch BHI-US Universal Switch II.

This converter requires a new manufacturer specific cluster:

Hi @slugzero, first of all thanks for adding support for this device. I noticed that the actual button presses are not exposed in the zigbee2mqtt webinterface and are also not available (at least not out of the box) in e. g. homeassistant.

Nevertheless, when pressing a button, it seems working and the MQTT messages are correct (e. g. for short press upper left):
zigbee2mqtt/friendly-name/action: button_top_left_release

Since I'm not very familiar with this project, is there anything I could do to get this device working as intended? I would be grateful for any suggestions and am also willing to do some work / get into the project.

Hi @mldytech, you are right, the action expose is missing from the device definition. Note that it should work in Home Assistant nonetheless: Make sure you have sent all actions at least once (i.e. press and long press all four buttons) while HA is running. After that, the entries should show up in the list of device triggers.

It will take me a little while to change this, because the device is in my "productive" network rn. But if you'd like to give it a try yourself: Adding

e.action(['button_top_left_release',
	'button_top_right_release',
	'button_bottom_left_release',,
	'button_bottom_right_release',
	'button_top_left_longpress',
	'button_top_right_longpress',
	'button_bottom_left_longpress',
	'button_bottom_right_longpress',
	'button_top_left_longpress_release',
	'button_top_right_longpress_release',
	'button_bottom_left_longpress_release',
	'button_bottom_right_longpress_release']),

to the list of exposes in

zigbee-herdsman-converters/src/devices/bosch.ts

Line 1886 in da65b1a

exposes: [

should fix it.

The simplest way to do and test this is probably to copy over the device definition to a custom converter file as described here: https://www.zigbee2mqtt.io/advanced/support-new-devices/01_support_new_devices.html

@slugzero Thank you very much for your answer. You're right, the entries were already visible in HA.

I appreciate your tips / guide and will definitely give it a try on the weekend!
