Here in Baviera, Germany, by the end of this year, 2017, all houses do have the required smoke detectors installed. The house I have rented has a cellar, where my workshop and electronics lab for my hobbies is, a ground floor plus 2 more floors. Already for the use of WiFi we have 2 WiFi access points installed. One in the cellar in my workshop and one in the first upper floor. The reason being that the walls and floors are made using concrete and so they work as efficient Faraday cages making those 2 access points, we have Fritzboxes, a necessity to have WiFi service everywhere in our house.
My idea is to connect something like a RaspBerry Pi ZERO W to every smoke detector, so they can monitor when the sensor activates its alarm. The raspi would then pass this information via WiFi or Bluetooth to the next ZERO W. Each ZERO W would require a small display attached to report which sensor has issued the alarm and activate the local alarm as well. If we family members are in our bedrooms we would not hear the alarm issued by the detector in the cellar, for example. Same is when somebody is ringing at our door bell, I do not here it in my workshop.
Somebody wrote that a ESP32-OLED-Wemos-WiFi-Module-Bluetooth-Dual, URL-address:
**broken link removed**
would be a possible candidate for the sensors instead of a Raspi, as it already come with a small OLED display. I could not find out how such a board would programmable with the exception of the expensive Cadence SDK.
First question:
Has anybody experience with such a "mesh" kind of net as it should be pretty common in smart home installations.
Second question:
Can anybody tell me how to program the controller in the module? I have found no easy approach.
