I ordered a solar panel and a supercap.

Time to experiment with running a small weather sensor on the ambient light that I get (not a lot, basically in shade).

I don#t need much, I ran it and it averages out to 1.177mA over a day, so I the solar panel needs to produce 7 mA (all 2.8 Volts) for 4 hours to handle the daily usage. Basically about 20mW of power. The panels I ordered are rated at 250mW each, two for 500mW.

The would remove the need for a lithium battery, which is beginning to be terrible due to low temperatures.
