The ESP32 board is good - a GREAT place to start.
If you want a longer battery life, I recommend a RAK4630-based board.
LoRa devices are freaking cool.
A place for people who like to be prepared for realistic disasters both human created and naturally occurring!
We expect there to be thematic overlaps with outdoor, survival, general preparedness, self-sufficient living and resilience... also gear talk is welcomed wholeheartedly.

Most of my nodes are in enclosures backed by solar with a large 120Wh LiFePO4 battery, or otherwise hardwired to a power source with a 3Ah battery in the case. Portable ESP32 units are good for a few days of constant use with the 3Ah battery included.
Looking at getting a T-deck though, for when carrying anything with a cellular connection (even cell turned off) is going to be comprisable.
