2Air Quality in Home Assistant

I recently wrote about how to show bin col­lec­tion inform­a­tion in Home Assist­ant, and my next pro­ject was to pull some air qual­ity inform­a­tion. For­tu­nately I have a ‘Tado’ account which meant I could pull this inform­a­tion from their API using the fol­low­ing code

Update 26-Nov-2024

Tado pulled the pol­len data back in sum­mer 2023. Since then I’ve been using Tomorrow.io based on a guide on the Home Assist­ant For­ums, but it seems this has also now made pol­len data a “premi­um” only offer­ing., so I’m now look­ing for anoth­er option.

Accuweath­er may offer it as part of the weath­er plu­gin, but I already use that for anoth­er loc­a­tion, so I’m going to look at Kleenex (as per the guide here) or from the BBC (as per the info a href=“https://www.speaktothegeek.co.uk/2023/04/uk-pollen-count-forecast-in-home-assistant/”>here)

Updated 20-Dec-2021

This was updated to tweak an issue where home assist­ant con­verts the text value “none” into “unknown”.

Much of the inform­a­tion for this was taken from a thread on the home assist­ant for­ums, but I was able to add pol­lu­tion as well as pol­len inform­a­tion, and I also had to tweak the code to resolve an issue with “none” being treated as “unknown” rather than as a string of text. Lots of cred­it to Drillbit on the for­ums though.

Tado account details

• You will need some inform­a­tion for your Tado account
• Vis­it https://my.tado.com/api/v2/me?username=you@emailaddress.tld&password=yourpassword
• Near the top of the out­put you need the numer­ic ID that is lis­ted under homes: 0: id:
• Next, go to https://www.latlong.net/ and loc­ate your home and make a note of the lat­it­ude and longitude
• Next vis­it https://acme.tado.com/v1/homes/your-home-ID/airComfort?latitude=12.34&longitude=12.34&username=your@email&password=your-pass­word to make sure it loads

Code for home assistant

• Add the fol­low­ing code to your configuration.yaml
