@srgdamiano – You have done some good work on developing/improving the ModularSensors library. After struggling to get the “logging_to_EnviroDIY” sketch to upload consistently to EnviroDIY portal, I have found the ModularSensors library to run much better with less HTTP POST timeouts. Before I switched I ended up heavily modifying the older example sketch to get it to work with the XBee S6B WiFi module reliably. The ModularSensors ran pretty much right out of the box with minimal HTTP POST timeouts to EnviroDIY portal. The only issue I notice is the NIST clock update routine usually does not work.
