Hi all,
I have the following use case:
Monitor the Grid Voltage (in my country we busy going through Load reduction constantly). What I am trying to achieve is the following:
- Grid goes below 200V - Do a bunch of things (turn off some shelly & sonoff switches, notify me via PushOver)
- Grid comes back i.e. over 200V - Do a bunch of things (turn on those switches) notify me via PushOver.
@Steve-Mcl was kind enough to provide a flow which is almost perfect found here
Which is something like this:

Which works great for when the grid goes down and comes back up however there is one adjustment which I can't figure out.
When the grid comes back i.e <= 200V I want it to turn on the switches and notify me but then the grid fluctuates between 200V-230V constantly which means it constantly picks up the change and carries on notifying me. I just want that to happen once, when it reaches 200V then stop (Because as long as the grid is above 200V I am good.
So basically IF the grid drops below 200 - DO ABC, IF the grid comes back and stays above 200V DO XYZ
