I’d like to build an #ESPHome device for data collection/display during an extended #poweroutage.
Ideas
1. powered normally via #USB / #ACpower
2. support second power source with AA/AAA battery backup: obtained easily, replaceable, no recharging
3. collect from cheap/common #Bluetooth #sensors (i.e. temp)
4. does not require a network (i.e. network down in power outage)
5. store data when #HomeAssistant is not available
6. upload data later
7. show information on a local #display -
