Operating entirely off-grid, the remote sensor node utilizes solar power and aggressive deep-sleep optimizations to monitor environmental conditions indefinitely. To bypass the extreme battery drain of standard WiFi, it broadcasts lightweight packets via ESP-NOW to a continuously powered indoor Relay node. This Relay acts as a bridge, forwarding the data into a local Python Flask server where it is logged, archived, and displayed on a…
