Hi Shelly experts,
I am new here and trying to troubleshoot issues I have with my new Shelly 2.5.
It is sending constant signal to both SW ports.
When measuring voltage against null (N): SW1 has 220V, SW2 has 160V
When measuring between two SWs it is 60V.
When connecting them to double (1-0-2) signal switch, which I want to use with it to manage my roller shutters, only one direction works - when signal is sent to SW2 (160V) because obviously there is some voltage diff which it can notice.
Other signal is not registered by shelly at all.
Both output ports seem to be working fine, I am getting nice clean signal on both of them when using app, just getting no reaction when pressing signal switch.
Is it possible that it tries to switch on N signal somehow?
I tried both roller shutter and light modes, also few firmware versions.
Tried also with and without SW and Output wires boeing connected. Also with only 1 L input (Shelly 2.5 has two L inputs). Always the same result.
Also tested Input and SW of Shelly for short circuit (with multimiter buzzer) but no, no short circuit seems to be.
Shelly is really powering both SW inputs itself and with different voltage!
Any ideas what I might be doing wrong or I just got defective device?
Thanks for any info and help.
Best,
Igor
