19/07/2021 10:45 All the gases and temperature and humidity (but not PM) stopped simultaneously at this time.

30/07/2021 While doing the Firmware Upgrade, noticed that the solar panel looked skewiff, as if it had been hit/bent. Also the bracket for the pod also looked twisted, and had been popped out of its 'pins'. This may have been vandalisation (though above casual reach) or possibly a bus or high vehicle/ladder hitting it?

It may be if it was an impact, the gas board with the gas sensors is is damaged?
