I am searching for a (preferably Shelly-based, as I do use many Shelly products) solution for replacing some 220V DIN rail-mounted 2-pole / double phase step relays (e.g.Finder Type 20.26) for lighting control.
The current functionality is:
relay output 1 OFF, output 2 OFF -> light switch pressed -> relay output 1 ON, output 2 OFF -> light switch pressed -> relay output 1 ON, output 2 ON -> light switch pressed -> relay output 1 OFF, output 2 OFF
(the relays are controlled with single-pole push-button/momentary switches)
Can the Shelly PRO 2 operate in this manner? (I remember reading somewhere that the Shelly 2.5 could operate in a similar manner)
