FVXM25F units

[Ginoooke]

Hi,

I have been trying endlessly to get this to work...

I own 3 FVXM25F units.
S21 port pinout is

1. 5V
2. TX (5V)
3. RX (5V)
4. VCC (14.5V)
5. GND

Components used:

• D1 mini ESP8266
• mini560-pro step down 5V
• optionally: 8 channel level converter TXS0108e

Software was installed via Studio Code Server.

The D1 boots correctly, wifi changed to homenetwork, fixed ip adress given, ...
If I start the D1 powered via usb (connected to pc) and without any other connections software loads in a couple of seconds.
If I then connect the D1 to the Daikin unit (either with or without the level converter) the system either simply does not boot/connect to wifi or connects very slowly.
I can then eventually turn on the AC via the webpage, but when selecting a different setting (eg fan speed) AC turns off again.

All connections (power and other lines) were tested, retested and re-retested - even with different components.

Any suggestions? :-)

Thx!

hey,
you are using pin 2-3-4-5, right?
i'm curious about slowness: are you sure you modified the remote debug library as suggested? that library if you let websockets enabled commonly overlaps with async webserver giving terrible slowness
once you have stable system, we can look at the commands :)
i'd also try (if you can manage to get there) to connect the esp to the daikin but powered by your pc (so connect usb on pc side and TX,RX and GND daikin side, i'd not connect VSS)
