What is it?
It is a compact wireless mini weather station with a 2.9 Inch e-paper display with screen resolution of 296x128 pixels. The device has an industrial look, at least I wanted to achieve this. The sensor has very good energy efficiency. Powered by nRF52 multi-protocol chip (BLE, Zigbee, Thread, ESB). The device comes preinstalled with MySensor Protocol (ESB) based wireless networking software - www.mysensors.org. Can use both a ready-made device and a device for developing your own software right away.
You can see how it works in my small video - https://youtu.be/0yZfeFMDKKY
