I have a sewage ejector pump that is only supposed to run for a few seconds at a time. Sometimes the pump will get stuck and run constantly and never shuts off. I was looking for ideas on how to monitor if the pump has been running for more then a minute and to alert me when it does. The pump plugs into a normal outlet so I was thinking I could get a smart plug and monitor the power usage but I am not sure how to get alerted if the pump is drawing power for more then a minute. Any ideas?
