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?
What's your end goal? To be able to control the SWG with either the timer or shelly, or just monitor power?
If you just want to monitor power, leave shelly on all the time and don't use the switch input at all.
Like he said, no need to use the shelly for switching if you only need power monitoring.
Or you can use a Shelly EM.
