Support for new features ptvo.switch

The ptvo.switch is at version 2.3 now and some nice features are added. I would like to use some of them but I think they are not supported by zigbee2mqtt. I did read the manual on how to add new devices but can’t get my head arround it, yet.
The features are here https://ptvo.info/zigbee-configurable-firmware-features/
Who can help to get the features working? For example the PWM outputs, I do get a report back from the node with the current values in it, but sending a new value does not work. I do not now the right MQTT command. I use Node-RED to control the nodes. Thanks.

That would be fantastic. This PTVO https://ptvo.info/zigbee-switch-configurable-firmware-v2-210/ is really good to build your own devices. How can we get this into zigbee2mqtt and finally HA :slight_smile:
