Rule for zero or excessive energy consumption using energy plug meter?
Please help dear Cyber Rule Creators,
Objective is to get an email or sms if a pump has zero power/energy consumption for a certain time (lets say 30 min) - i.e pump is dead or if energy consumption exceeds a certain value indicating continuous pumping that kills the pump in the long run. I have an Aeon energy plug meter that monitors current power consumption (W) and cumulative consumption (kWh) for a ground water pump (that works intermittent thanks to a water limit switch).
Can some experienced rule creator hint how to create a rule that compares energy regularly, for example every hour and 30 minutes later and send an email if difference is zero or exceeds 0.25kWh (continuous 500W for 0.5h)?
