Firmware Revision History

Version 2.00   June 18, 2020

This is a complete rewrite of the firmware in order to reduce power usage, enhance functionality, and support additional addon sensors for other applications. There are slight changes to some prompting, and the power up/down cycle. The Bluetooth support is totally redone but hopefully compatible.

This version also supports the new non-mirror Heat Guardian set with a base and mobile.
