Re: Is it possible to use LCDs with ST7735&ST7739 controllers??

Re: watchdog timer

Did you between moving from Tasmota to ESPEasy wipe the flash?

If not, can you try giving the command "erasesdkwifi" and then power cycle the board?

If that doesn't help, please backup all files on the file system, flash a blank image, re-flash the firmware and restore the files.

Re: After old firmware Release 147

Please note you can't update via OTA on an 1MB flash unit.
So you need to flash via serial.

You could consider replacing the flash chip for a 4M version, which makes updating a lot (!!) easier.
Also 1M builds are quite limited to make it all fit.
