How to make cloud connected voltage monitor as eco as possible?
Hello,
That is the car usage of esphome.
I would like to monitor my caravan when touring.
I would like to make tiny project where I would monitor voltage, current with Ina3221 board (3*ina219)
and push that readings into the cloud (or my home assistant local instance).
I also want to make it as economically, as possible - so I would like to use deep sleep (please let me know if that is good idea) when voltage is about 12V. In that time I would like to wake up the board(s) about each 1 hour, check the readings, put into the cloud, and sleep.
And…
When I came into the car, or I will start it, I would like to start the boards instantly, without sleeping it.
So, in that time I want to monitor usage of all receivers connected to ina3221 until the voltage in car downs to 12v (when the engine will stop).
After the engine will stop, It should came back to deep sleep>1h>wake>deep sleep loop.
Is that makes sense?
That is only basic functionality, I would like to add some coding later, to monitor specific channels of ina3221.
I will be very happy for any replies from you
