Home Assistant

Home Assistant (HA) brings together all my gadget information so that I can see it in one place at any one time - either my PC or my phone.  My phone has the HA app so that HA can trace it, etc.

I set up HA on the Raspberry pi model 4.  See here for instructions on HA.

I did try some of the various setup options but settled on the basic one.  HA is an operating system  in itself so I thought that the separate model 3Bs could be independent and send it data.  This seems to work well.

Introductions

 At Martlesham Heath in Suffolk, UK, we have a small group of enthusiasts who like to tinker with gadgets and write code to make things work.  We meet most Fridays for a coffee and a chat about our own projects and the progress, or not, that we are making. Our website is https://www.codingforcodgers.co.uk/  This blog shows what I have achieved in 2022 and in the following time period. In 2022, I was given two Raspberry pi model 3Bs and I bought a model 4 starter kit too.  On the model 4, I have installed Home Assistant.  This brings together all information and control of all the home gadgets such as lights, sensors, my weather station, etc. I have posted a page per project to describe what I have done.

Weather station

Image
 I have a Raspberry pi that collects data from my weather station and transmits the data to Home Assistant and also to the Codgers website. Data includes atmospheric pressure, temperature, humidity and rainfall.  Pressure is measured using a BMP280, the next two variables use a DHT20, and rainfall is collected with a tipping bucket and recorded every 5 minutes. The instruments are housed in a home-made Stevenson screen. In February 2024, I added a DS18B20 temperature sensor, which is waterproof.  This is a "1-wire" connection to the pi and needs a resistor in the circuit (4.7K but I used 10K). I buried the sensor at 10cm depth under the lawn to record soil temperature. In December 2024, the top blew off in a storm and data went a bit haywire so there is a two day gap in data.

Vehicle tracker and boat sensor display (Project Samosa)

Image
Project Samosa The yacht club (APSC) bought a Jeanneau 36i in November 2024 and we thought we could add a few extra sensors and display data on an app using a tablet. MIT App Inventor is quite easy to use and free.  I have bought an ESP32 that gathers the data from the sensors and sends it to a pi Compute 4 (Sail Assist) that also sends boat data to the tablet. More later... Vehicle tracker (not used any more) My "van pi" (thanks Sue H) has various sensors attached. I have an independent leisure battery.  I have to charge this separately, as and when, at the moment.   Battery monitoring: I have an INA219 battery sensor that shows voltage, and current / power being used. I have a DHT20 sensor that measures temperature and humidity in the van (but in a cupboard where the sensor is located). A python program I called vansensors.py collects the data and sends it via MQTT to HA. I have a USB gps unit that lets the pi know where it is.  I have a program, gpsdatatest....
