WAQI (Air Quality) stopped working just before the forest fires!

Hello, there are huge forest fires in Canada, and a lot of smog now, I used WAQI to automate my ventilation and filtering, but now after some updates it’s not working, and it happens at the only time of the year I really need it.

Has anyone had a similar issue, or a quick idea how to make it work again?
Thank you

Possibly because it’s not reporting?

This happened to me too in Jersey City. I had to do a HA reboot for it to refresh its value. Not very ideal. The value it was stuck on was from 1 week ago

It is reporting, but I’m seeing Unavailable in Developer Tools
Regina is just an unrelated sensor added by WAQI, not the city I’M monitoring I don’t know why it adds all those cities, I only have 1 location:


It looks like there was a fix about 6 hours ago. I’m not sure if the changes will make it to our instances of HA in time though.

AirVisual Cloud - Home Assistant may be another option to get something in play if you need it now.

Can confirm, the Home Assistant 2023.6.1 update fixed the issue, so the outage lasted the entirety of week where there were forest fires in my region, bad timing I guess. Thanks for the check.
