I make stuff with things
I'm thinking of using another esp32 to power cycle my inverter in the event of it hitting low voltage cut off AND AFTER a reasonable return voltage has been reached. The property is remote and I'm not always there so having something like this would be really nice. ...Basically a device that prevents me from driving, hiking, flipping a switch. We use the property for guests too.
aaaaanyway, I think it'd work like this, in the simplest terms:
With a couple of the various higher voltage sensing devices compatible with esp:
1. detect inverter output_voltage
2. detect inverter input_voltage
...I think this would be the least intrusive/dangerous to the inverter as opposed to some closer integration with the inverter.
3. series wire into rocker the switch using a relay
4. The logic in pseudo-python:
power_cycle():
open relay
delay 3000
close relay
loop():
if output_voltage is null
if input_voltage >= <return_voltage>
power_cycle()
I'd also be logging everything to my existing AWS IoT Core setup. ...until I drop that for Blynk.
Total cost of this hardware would be about $16 including the enclosure. Build, programming and install time would be maybe 2 - 3 hours
What do you all think? What would you do differently?
