Buffer & Batch Uploads
Store offline and sync when WiFi returns.
WiFi Isn't Always There
Real devices lose their connection: the router reboots, the signal drops, the cloud blips. A good logger keeps working when the network disappears. 📶
Don't Drop Data
If you only send readings live, an outage means lost samples forever. The fix is to store offline first, then upload once the network returns.
