I’m looking around for DC or USB powered thermometers but I can’t seem to find any. Granted, the battery powered ones last many years, but I’m looking to keep my options open. Zigbee devices are preferable. Anyone know?

Picos are very bad for battery applications. If you do end up doing this, make sure it is mains-powered like your original thought.
Esp32s, MSP430s, and nRF chips have sleep currents down to around 5uA or less.
Picos have sleep currents of 1-4mA. That is 1000x higher and the battery will only last for a few days instead of a few years.
Thanks for the insight, good to know.
