I'm controlling our 240V Hayward THP VS pool pump with HS4 via external relays--Sonoff 4CH Pro. I don't have a dedicated pool automation system (e.g. Hayward Omni), and I want to monitor/verify pump operation beyond HS4's assumption of relay status. As far as I've been able to determine, there's no way to intercept Hayward's digital control input/output at the pump control panel.
With my limited experience and knowledge the simplest is probably multiple adjustable current switches calibrated to the 3 speeds I'm using (not sure yet if would need them on both 120V legs?). A node MCU or other tasmota device to monitor the switches and report to HS4 via mqtt. But I would guess variable current monitoring is possible using a current transducer, right? Anyone know of sample project instructions doing it--preferably with tasmota as I'm relatively familiar with it? My googling hasn't turned up what I'm looking for.
Am I missing any other low-cost options or reasonably priced pre-baked solutions? Upgrading to a full-blown pool controller with a HS plugin is way overkill and more than I care to spend.
Thanks.
