Looking at the incoming data – which is continuous from the Lochan node – I noticed the temperature flatlining since Nov 25th which shows the box is probably in snow now:

This temperature graph shows that the temperature of the lochan node is flat-lining. This normally indicates the box is snow covered and hence thermally insulated.

The battery charge – which was beginning to show signs of reduced solar charging (deeper dips) – also shows a sigificant drop. It is possible the solar panel – which is mounted on the ground – has some snow cover.

This plot shows the normal overnight dips and solar charging cycles becoming deeper. Oce the snow has settled the charge is dropping to around 70%.
