How to do this when your not sure of power usage

#1

Hi All,
this is used with a sump pump I like to do it without using the 200w and 150w
as I am not sure what the amps are could I just us power on change

It depends on the data that’s being sent to you. What kind of energy monitor are you using? Why don’t you want to use watts?

Hi I should have made my post a bit clear
I am not sure if it is 200 watts and 150 is there a way I can do it and use power change
but not have to give it a number

Power changes all day, every day… If you don’t use specific numbers, it will trigger non-stop!

#5

What are you using to monitor energy? What readings are you getting? I have a Zooz double plug that gives a lot of information.

it is only one device and that is the pump it does not run often but it does

#7

What I mean is, even if the pump does not turn on often, the power is still changing, all day, every day. You need to use numbers to limit the amount of triggers…

Could you log the data to InfluxDB/Grafana, a google spreadsheet or webcore’s fuel stream? Then you might get a better idea what to set your triggers to. I’m doing something like this for my Chevy Volt charger. Although, I’d probably just pick a very low number, like 5 watts.

If pump power > 5 AND sumpTriggered = False, then set sumpTriggerTime = $now, set triggered = True.
If pump power remains below 5 for 5 minutes AND sumpTriggered = True, set sumpTiggerEnd = $now - 30000, set sumpTriggered = False

Adding the 5 minute delay will keep it from flapping (if it does that).

Here’s screenshots from influxdb/grafana:

Here’s my activity monitor:

For my energy monitor, I’ve got a zooz zen15. It’s supposed to be rated for 15 amps, and the charger is only 12.
