We live in a house built in the 60's, and we close off some rooms we rarely use to conserve energy. This year we have been tracking temperatures due to the installation of a new heating system. Wanting to collect more detailed measurements, I am creating a sensor network to collect temperatures automatically from rooms and outdoors.
I am rolling my own IoT device, and will collect data on a local server. It will use an Espressif ESP32-C3 processor that handles the wifi. The device will be powered from, optionally, an outlet or battery.
I intend wake from low power mode, measure the temperature, connect to our LAN, write the measurement to a server, then return to sleep.
While still at the early stages, I have already implemented a simple prototype that receives data from an ESP32 device, and delivers the information to a database. Eventually I will have multiple stand alone devices feeding data to the database.
I expect this project to go quickly, and the future steps include:
