General Voltage and first tests

[janczmok1970]

I would like to have a bit of info, what voltages are needed to trigger it ? and How to test correct operation with a power generator.
As i have a fully charges 18xxx batterie inserted, i still not see the unit lighten up or shows and LEDs. I would assume when the battery is inserted, unit shows some sign on live ?!?

it will not show signs of life until it is triggered, for testing purposes, you can briefly connect "ET to battery +" and it will trigger ESPBel-MAX, By default firmware it will stay enabled for 15s max or until the "notification button is pressed.

Triggering voltages are

"ET" Input 3.3-5v DC Max
"DB" Input Optocoupler ~2-30v AC/DC Max

Okay, that triggers it. Need to optimize the setup a bit more. Tomorrow i will test it further with the original bell.
But can you add the yaml files and the jpg for homeassistant to the project ?

Yep, I will add a .IMG. and which YAML do you want? Automation?
