OW DISCONNECTED while the temp sensor seem to work

[kmate]

Hi!

I have an iSpindel that had some minimal damage due to insufficient insulation, i.e. the wort went in a bit... I disassembled until I was able to remove the switch and clean it - according to my measurements all the other components & connections look OK after re-assembly.

While I was there I thought it's a great idea to flash the firmware to latest - version 7.3.3.

Now I have a strange effect: I cannot save the WiFi config as it crashes. Presumably because I also get repeatedly:

ERROR: OW DISCONNECTED
OW Retry

BUT, if I go to the info page, I get totally meaningful temperature values, even when I touch the sensor it detects the warm up caused by my hand.

So, I guess the config save crash is due to the OW issue, but then, why is that present, if the sensor looks to be working, and all the connections / resistance values on the 3 legs of the temp sensor look OK otherwise?

Any help is appreciated, thanks!

Additional info: if I log t in the beginning and the end of this block, I get:

-127.00
ERROR: OW DISCONNECTED
OW Retry
28.25

which means that it first always thinks that it's disconnected but after a retry it just returns the value fine...

Also myData.OWpin looks to be 12, which is D6, which looks to be right.

And here's the exception I'm getting when saving the config, if it helps anything:

*WM: Sent wifi save page
ERROR: OW DISCONNECTED
