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?

Switch mode is set to ‘Follow’. I do see now that the page is showing the input as ‘OFF’ where previously it wasn’t changing from ‘ON.’ Perhaps some leaking current or a massive delay.

More testing tomorrow!

Edit: Current leak confirmed. :( Randomly went back to ON and switched it on. But at least I know it’s not a Shelly issue?

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.
