El Shelly H&T (el de temperatura) usa una batería y el Shelly Door/Window 2 (el de puertas y ventanas) usa dos baterías.
Si cada dos mese hay que cambiar las baterías, no son nada útiles.
I have a "Shelly Door/Window 2" device that uses CR123A batteries that were not included. I tested the device and used some batteries that I have at my disposal and it worked well until the device discharged and currently, although I tried to recharge the battery, the shelly device did not turn on. Do you have any advice on how to repair the device or does anyone know the causes of the failure? Since it was not due to any blow or contact with liquid or other external problem that could damage it, I appreciate your advice.
