• Weathercloud ID and password are verified for exactly 16 and 32 bytes, otherwise, no connection is attempted.
• Some customers reported WiFi disconnecting at Midnight. We were resetting the WiFi module every night to force a reconnect once per day, but we removed this logic.

Version 4.0.8:

• Fixed bug where temperature was set to 0.0 and Midnight.

Version 4.0.7:

• WiFi SDK update.

Version 4.0.6:

• After DNS lookup is verified, it will ping once per minute.
