    I monitor all my 240v devices (clothes dryer, water heater, pumps, etc) with PZEM modules and Tasmota.

    Works perfectly and you can monitor / trigger events based on wattage, voltage, etc.

    I use it on one 120v leg and simply multiply wattage *2

    Also Since Tasmota can support 3 PZEM on a single controller, I have built triple PZEM units which I installed in my main breaker panel.
    you can just clip the half cores to any appliance lines.

    Add InfluxDB-Grafana and you get all the stats and fancy graphs

    This looks great. I'll dig into it in the morning. Thanks!

    If you're meaning a whole-house monitoring system, I would love it but due to the main and subpanel configuration that evolved over the life of my house it will be complicated and expensive. I've heard a little about the "smart" systems that claim to determine usage of individual devices/equipment from a single monitoring point at your main service, but I'm skeptical. For now I'm looking for an economical way to just keep tabs on the pump (and actually my pool vac booster pump too).

    First priority is just to prove operation. I.e., is it pulling current. Second is to verify speed which I can know by how much current is being pulled.

    started a topic Monitoring pool pump operation

    Monitoring pool pump operation

    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.
Working...
