What are Tasmota Device Groups (DGR)?
Device Groups are lightweight UDP broadcasts that mirror commands, states, and telemetry among up to 255 devices without a broker or server [Tasmota Docs, 2022].
[Youtube] Tasmota Device Groups for OpenBeken - single light switch to control lights, dimmer, color
TL;DR
- A Treatlife-style smart switch running OpenBeken uses Tasmota Device Groups to control multiple smart bulbs’ power, dimming, color, and temperature from one button.
- The switch keeps its relay set to AlwaysHigh and sends on/off commands over DGR instead of cutting lamp power, so the bulbs stay reachable.
- The setup works over UDP with Tasmota Device Groups, and it can pair devices using different WiFi modules such as W600, BL602, BK, and ESP.
- The same light group can also integrate with Home Assistant, avoiding the usual case where turning off the wall switch makes HA lose control over the bulbs.
Generated by the language model.
Here we will show you how to use Tasmota Device Groups to pair multiple smart bulbs with a single smart switch. The smart switch will run OpenBeken and will allow you to control the lights power state, dimmer, color and temperature with the single button. The switch relay will always be on, and the smart bulbs in the lamp will follow the main light switch state via Tasmota Device Groups protocol. This will allow you a seamless integration of lights with the switch and Home Assistant, without having a "my main switch turned off bulbs and now HA lost control over them" scenario.
Some main conclusions from the video:
- Tasmota Device Groups protocol works on OpenBeken, so you can pair with Tasmota Devices
- with OpenBeken, single button can give you full control over multiple lights
- lights can have different WiFi modules (W600, BL602, BK ,ESP) and they still pair with switch well
- DGR protocol works without any server, it's using UDP, so you can do this automation without Home Assistant
- the simple trick is to just set the relay state to "AlwaysHigh" and let the switch turn on and off bulbs via DGR, and not by disconnecting their power
Of course, you can also pair that switch with HA and that way you can also control whole light group.

Thank you for watching. We would also like to thank our users for sending us devices shown here (the Treatlife switch and the BL602 bulb) - this video wouldn't be created without your support! If anyone also wants to support us, consider doing a donation at: https://www.paypal.com/paypalme/openshwprojects
Feel free to ask any questions, we're here to help you with device setup and pairing with HA.
