I bought a bunch of Sonoff devices and decided to upgrade their firmware to Sonoff-Tasmota.
By replacing the stock firmware, I can have complete control over the device. Sonoff-Tasmota uses MQTT as the underlying protocol for communication between a broker and the device.
After using MQTT Dash for some time, I decided to build a Progressive Web App.
Server runs on a local Raspberry PI model 3 B+ which has the following services:
I currently own 6 Sonoff devices, which are connected to the following appliances:
I also have a bunch of sensors connected to a Wemos D1 Mini (flashed with the same firmware above) in my living room:
All devices establish a connection to the MQTT broker and report their state while also subscribing to a control topic, allowing you to switch them on/off.
Server runs as a daemon and subscribes to all sensor topics. Some logic decides when to switch the room heater on/off.
The UI is built on React and consists of simple components that allow the user to switch the appliances on/off and view sensor, weather and derived data, like the "real feel" temperature.
The browser keeps a connection to the MQTT broker over a Websocket.
Not sure, but I recently started playing with electronics and found home-automation to be my new hobby.
I'll keep experimenting with dev boards like Arduino, NodeMCU, ESP8266 and Sonoff devices. They are low cost devices that allows easy customization.
