Trying to use a Shelly Plus 1PM to monitor my pool's SWG, but the switch function isn't working
(lemmy.world)
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?
Lots of reports out there of people having current leak issues when doing anything more than the usual light switch configuration. Personally, I'd just put a dumb power meter on it and leave the chlorinator hooked up to the pump line.
