debug error message

[macmpi]

within error/<hostname>/comms: {"protocol":"S21","cmd":"FT","nak":true}
Which meaning?

[revk]

We tried sending a command FT and got a NAK meaning that the unit does not understand it, so we'll stop sending those.

[macmpi]

Ok, thanks.
What is FT command? could not find in https://github.com/revk/ESP32-Faikin/blob/main/Manuals/S21.md
Had same with FS command too.

[revk]

It is only set when debugging enabled. I am not entirely sure what it is. There is a discussion thread on the research being done on S21.

[macmpi]

info/<hostname>/cannot-tx: {"protocol":"S21","cmd":"DH","payload":"31303030","text":"1000"}
related?
What is difference between error on comm and cannot-tx?

[revk]

I am surprised I did that one as info not error.

[macmpi]

under info/<hostname>, I have:

tx
upgrade
automation
cannot-tx
s21

[revk]

Good, I am sure there are many more
