AQI service failed...

[Tim Tuck]

Hi all,

Everything was running just fine until 6 days ago and now this happens...

AQI values are coming in and being stored in the aqi.db so I'm a bit
lost as to why this should suddenly happen.

The end result is that my pm2.5 graphs in the Belchertown skin is not
drawn.

any help appreciated!

thanks

Tim

Don't worry about this, the batteries were near flat and with the morning temps being in the single digits the batteries were going on and off causing the unit to behave weirdly.

A set of fresh batteries and its all good now :)

cheers
