Notify when Pump offline
Hardware
Option 1: metering from electrical panel
Previously purchased a TUYA ZigBee Smart Circuit Breaker Power Metering 1P 63A before realizing that the pump is one a “Two Single‑Pole” breaker switch. The metering device needs to be hooked onto the same circuit as one of the poles (but not replace it). This will require electrican’s help.
Option 2: metering from pump panel with use of clamps
wires are very clustered togther. Uncertain if this poses a problem.
Notification
Graphana would get steady interval payload of the load status. Trigger notification when payloads are absent after X minutes. Trigger notification when no load has occurred after Y hours. Email notifications to multiple recipients (not self hosted email servers). Look into possibilty of marking them as urgent.
