ESP32 Doorbell via Telegram
It happens to all of us — you’re at home and there’s a caller at the door but for some reason or other you do not hear the doorbell buzz or ring! No problem if the person at the door has your phone number handy as he or she will be able to get hold of you. In all other cases, Catch-22 governs, which is especially annoying when you stayed home desperately waiting for a parcel delivery within a certain time frame. Here now comes a DIY project to end such inconvenience.
