While the Fermentrack flashing seems to be WAY better now than it was back when I first found this and played with it, in my opinion, your Windows based flashing utility is quite painless... So no OTA wouldn't hurt my feelings any. But in my research on these units while I was having issues, it seems there are 4, 8 & 16MB variants of the WROOM ESP32, and then there's the WROVER with similar 4, 8 & 16MB variants - What is the feasibility of 'migrating' to one of those with more than 4MB? Moving to one with double or quadruple the flash might open the door for a unified BrewPi/TiltBridge as well somewhere down the road.
