I'm using Home Assistant with the Pentair IntelliCenter integration and would like to be able to know when the acid pump and SWG are on to monitor dosing. Since this information is not available via the integration, I was wondering if there was another way to do this. I was looking at using the IntelliChem relays, since one is used for the pump. However the SWG is turned on via a control message. A light sensor on the SWG LEDs seems like a kludge. Any ideas are appreciated. TIA
