When attempting to add the dimmer via zigbee integration, the available controls are to turn on/off the lights. There are also two adjustable fields regarding dim speed and another to configure the turn on brightness. The turn on brightness does not seem to alter any of the brightness levels when turned on. I attempted to use the production shelly firmware 1.7.99 and 2.0.0 beta1 with the same results.
In wifi mode, there is ability to : calibrate, configure inputs, control the dim levels and all operate as intended.
Just wondering if the zigbee integration will be supporting the wifi abilities in the near future?
