Heishamon for F-Series HP

[ErnstFinkAG]

We use a Panasonic WH-SXC09F3E8 with outdoor unit WH-UX09FE8.
Naturaly we get 0% valid packets via heishamon over CN-CNT or CN-NMODE port, because F-Series is not supported.

Is there a way to implement F-Series Heatpumps?
Or are F-Series communicating in a completely different way than the newer Series?
I could share captures from uart console, if needed.

Try to find out. Usually H series and later don't talk or spit any data to uart.. device needs to send request to it, and pump respons on request. So you get 0% because request is wrong or it's impossible to get that data via this port.. so it will be hard to get anything till you find device which talks with pump, and be able to capture it's traffic.

The board in my F-Series seems to be very talkative.
Via uart i get, about every 2 seconds: (no magicphrase or question sent)

If i compare the values (hex to dec) to my Webui (Panasonic HPM-800F22), they lineup.

Oh, that's completely different protocol and decoding.. i doubt heishamon will able to do this

[frankdornig]

I´m running a D-series and would also be happy about an implementantion of the older protocol.
Any alternative solution is appreciated.
Should be tons of these older systems running around the world.

looks like every 2 seconds as well
