Cross-posting this here since it may be relevant to the current discussion: Blue 2-1 - Z2M, Groups, Binding, and Multi-Press Actions Troubleshooting
*Sonoff 3.0 P-dongle with latest z-stack firmware
*Bulbs on shipped firmware
*Running most recent Z2M release
*Switch wired to smart bulbs and Aux switch, in Smart Bulb mode
Signal quality to the switch is strong and reliable. However, whenever it is bound to a ZigBee light group, actions are not received by Z2M even if I “wake” up the switch with other presses beforehand (no messages in the log for the switch_name/action topic, only what appear to be state change messages for the switch). The switch still reliably controls the bound lights however. I’ve tested with some Juno ceiling wafers and recent Hue bulbs with the same results.
If unbound and removed from the group, actions reliably are received by Z2M with no “waking” necessary.
Based on this, at least in my case it does not seem to be a signal quality issue, but some conflict with ZigBee binding.
