An idea I’ve been wanting to do for a while is to use an old phone as an IoT device. A second-hand smartphone is potentially a cheap way to get a processor, screen, and storage. The phone needs to be hackable – I think an operating system like LineageOS or JanOS needs to be installed on it. LineageOS has the best support for different phones. In order to be useful for IoT, the base phone should be extensible to add sensors or micro-controllers.
I’ve had two new toys arrive today! The Raspberry Pi 3 Model B+ that was released yesterday, arrived today. This is great turn-around by Pimoroni! I’m planning to put Home Assistant on it and use it as a local server.
SuperHouseTV have a great video on using the Sonoff, Arduino, OpenHAB and MQTT to control your house. Jon demos using the embedded software/cloud solution to control a light, as well as flashing the firmware yourself and setting up the Sonoff for over-the-air updates and controlling with MQTT. Well worth a watch!
