I’m using a Sonoff ZbBridge fashed with Tasmota 8.5.1. With Tasmota firmware, I can control and read the status of zigbee devices over mqtt. It works great with various Aqura and Sonoff Zigbee sensors so far. I started adding my zigbee bulbs to this network and faced a problem.
Autodiscovery for ZIgBee is not supported by Tasmota yet, so not a big deal, I created a manual configuration for an mqtt light using a template schema. It works great for CT lights but adding RGB channels is a challenge. MQTT Template schema requires setting and reading RGB values for lights. However, ZigBee protocol reports Dimmer and HS values in separate clusters, so does the ZbBridge - it takes and recives separate commands for setting Dimmer and HS values.
I wonder if and how I can overcome these problems:
- For controlling the light I need to convert RGB to Dimmer + HueSat inside the template. Unfortunatly, hass does not expose any such functions to jinja2.
- Light status is reported for the Dimmer and HueSat in separate mqtt messages. So it seems there is no way combining them in a template schema and calculating the RGB values, even if a helper function of hsv2rgb would have provided.
I would appriciate any help or hints here. My thoughts right now are around writing a custom integration, which would support autodicovery and proper configuration for ZbBridge connected devices. But if there is a shorter way, I would appriciate that.
