Z2M - 2 switches, 1 lamp - direct bind

Configuration Zigbee

Good day,

im looking into implementing a 2 way switch set up without the need of home assistant (direct bind). Both switches should independently turn on or off the light.

The Problem is that, each switch sends presumably a on or off command to the group. Now if the group has already the state on from the first switch, the received on command from the second switch is not turned into off. Which results into having rocking the switch again.
Is there something i have overlooked?

My set up: 2 Philips hue wall modules, 1 Sonoff zbminir2 relais.

no, i cannot add both switches to the light group „Korridorlicht_group“, i already tried but received an error. according to the documentation in Philips 929003017102 control via MQTT | Zigbee2MQTT this is expected

Hi everyone,

I’m facing the same issue as described here with two Hue Wall Switches and one lamp. The binding works, but the switches don’t toggle the lamp correctly unless I toggle them twice.

Has anyone found a solution for this?

Thanks!

Hello,

I figured out a partial solution to this with HA stepping in to toggle the switch in case the direct approach has not worked in 100ms delay. its not perfect, but at least if HA is not available (during restart for example) wife can still use the switches…
Hope it helps you in the meanwhile until someone can address that.

Basically, on click it saves the current light state, then compares after 100ms if the toggle happened. if not HA will toggle it.

  For this purpose, every actuator must have a binding with a

  assists by toggling the lamp. This eliminates the need for pressing the switch
  again for direct binding.
