Looking for affordable options to build a DIY semi-smart doorbell?
I’d choose an ESP and replicate what @Levent did but without Home Assistant. You could link two ESPs via web requests—one to the doorbell using a relay, another to a lamp through a relay. Or use a service that sends alerts to your phone from the ESP. After some research, I discovered simplepush.io. I already have an ESP integration and it offers free notifications for a limited time. But I’ve never tried it before; they provide a sample article for the ESP8266.
