Appreciate the concern, but my safety or the equipment’s safety isn’t at risk here. The cell I have (Pentair IC40) has an integrated flow and salt sensor. If either are low, the system is off. The low power draw of the system is specifically what I’m after to know to check the cell to see why it’s not generating.
I just installed the Shelly this afternoon, which is why I’m posting after not getting the expected result out of the switch input.
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?
