Howdy, Forum Friends!
Wyze Bulb Color firmware 1.2.0.429 is releasing with bug fixes and Wyze Thermostat version 1.2.0 is coming out with a new restart function and improvements to accuracy, connectivity, fan activation delays, and more! 
Read our Release Notes:
I received the new hub update, but not the thermostat one.
Did you get the thermostat update later? Thanks for letting me know!
- Improved the Fan Activation Delay mechanism so the fan will start to run after the furnace starts with a 15-minute delay when the control board has no internal logic
15 minute delay? Is that correct? That seems like a long delay to start the fan?
- Added a new temperature calibration equation for better accuracy
Any further info on that would be interesting!
