... but it's not working : only a red led is lighting, no ethernet connection setting (green light on the board, orange light on the router). I've tried with another usb cable, pressing buttons reset/rebootable during power it on... Still impossible to connect. I've tried with Putty and serial communication with the USD cable; without success...

Any idea is welcome.

Hi,

Tks for your quick reply. Indeed, with the check box selected it works better (o Smile

.

My project is about using this card in replacement of an existing alarm wired centrale. In the future, I'ld like to integrate this with larger home control system including ha and custom code. Do you know where to find information about creating custom py code for this card (by example how to change the displayed text, ect...) ?

Many Tks & have a great day !

you can config by esphome yaml, so that you can do anything.

best and easiest way is download KCS v3 firmware, enable mqtt auto discovery for home assistant. you not need config by any code, you can integrate A16v3 board to home assistant.
