New Dimmer2 installed to test bench for preinstallation before final installation.
Everything worked well, except physical switch ports aren't work at all.
L, N are connected, O to 60w bulb, L shared with momentary wall switch.
Momentary switch been changed between SW1 & SW2 interfaces with changes to config
Also tried to use N instead of L but no success.
Monitoring actions from MQTT server can't see any movement in there neither.
Using MQTT or http commands work OK and can control dimmer
Latest fw updated. Inside there are no any mark of any burn parts
It looks a like it was dead on arrival. Pity thing is I have bought this 6 months ago and waiting for installation since then
Any tips how t get it work? or how RMA process goes?
Edit: shelly1 &1PM are operating well in same test bench, so all switches and wirings are OK
