how did you do this?  I'm interested in the same thing for work :-)

two different door bell type buttons playing different tones would be even better.... one output needs to be loud too :-o


that way we can have one tone for sutomers pressing a button, and another tone for someone in the office pressing a button

zpyder:
Used esp8266 units with ESP-NOW. The ESP-NOW is a library that allows unit to unit data transfer without needing to hook up to any WiFi networks.

Essentially had a doorbell button unit, and a chime unit. And then I had an intermediary unit. Button sent to intermediary, when intermediary got a ping it then sent one on to the chime unit.

There is no reason you could not link any number of intermediary units, forming a chain of however long you need. Only limiting factor is power.

Doorbell button used a nodemcu 18650 battery module in a weatherproof box, and I enabled deep sleep mode on it. Got about a weeks battery life out of it as the nodemcu module had a bit of a drain compared to maybe using some other kind of esp8266 power option. All other units were usb powered.
