Right now if the pool timer is switched off, the SWG stays on. Likewise, if I switch the Shelly off and switch the timer on, the SWG stays off (and the pump turns on). Checking the SW terminal with a voltage sensor, it is hot when the pool timer is switched on, and dead when switched off. The workaround right now is the setting the schedule feature to closely match what the timer is doing.
Any ideas?
is the switch input treating the input as a momentary switch rather than a traditional rocker? I think they support both modes.
