Wi-Fi is great for quickly connecting devices to a network, but it is a bit power-hungry and therefore not the best solution for low-power sensor nodes that must run many years from a single button cell or that live from energy harvesting.

MySensors

A great solution for this type of device is MySensors, an open-source home automation and IoT project based on ISM-band radios, notably the nRF24 by Nordic Semiconductor and HopeRF’s RFM69.

 
Not only is creating IoT sensor networks with MySensors extremely easy, it also integrates nicely with Home Assistant. In this video we show you how to go about.
