@planckkonstante You should have a emsesp-device like:
(99) Unknown: unknown (DeviceID:0x17, ProductID:xxx, Version:04.01)
and we need the reported productID.
Also it is very helpfull if you can log some messages from the RC25. This thermostat seems to be a RC20 with additional option for outdoor-temperature control. It's possible that it uses other telegram-types for controlling than RC20.
Please set log-all, wait a bit more that a minute, download the log and post it here. We are interested in messages from 0x17 to all like: ?(0x17) -> All(0x00), ?(0xAE), data: 80 12 2E 00 D0 00 00 64
If you give some information about your system (room or outdoorcontrolled, actual reported outside temperature, etc.) it is possible to identify some values.

Well, thanks a lot already:

At the end of the log I played a little around on the Buttons of Rc25, disconnected and reconnected it to the bus
log (1).txt

Product ID is 151

{
"type": "Controller",
"name": "HT3 (DeviceID:0x09, ProductID:95, Version:13.06)",
"handlers": ""
},
{
"type": "Unknown",
"name": "unknown (DeviceID:0x17, ProductID:151, Version:04.01)",
"handlers": ""
}
]
0x17 is the only temperature sensor connected to the boiler..

Thanks, i've added RC25 to device-library. Please try the dev.

RC25 is compatible to the newer RC20 thermostats,and uses 0xAE and 0xAD telegrams, but the configuration telegram 0xAD is 9 bytes longer than for RC20 (23 instead of 14 bytes).
Unknown(0x17) -> All(0x00), ?(0xAD), data: 01 27 2D 00 44 05 01 FF 28 19 0A 07 00 00 F6 12 5A 11 00 28 05 05 00
I guess pos14 F6= -10°C is the minimum outdoor temperature. pos 17 !! = 17°C could be the summer/winter switchtemperature. But also for RC20 a lot of stuff in this telegram are unknown.

Well... I am on a windows machine and im not sure if I can compile the dev brach from source...

hmm i got platformiO + code + node.js.. compiling stops with error: wwwdata.h missing. also, at the beginning "command npm not found"

somebody a short hint?

[MichaelDvP]

The dev-bin is here. Please check the new (guessed) parameters and values and give feedback if all fits.

For compiling check if node.js is proper installed, check node -vand npm -v from commandline. The file wwwdata.h is generated from script by calling npm install and npm run build in the interface path.

[planckkonstante]

I am still struggling to compile from source...
However, I flashed the dev-binary a few days ago. Device is now listed, parameters are plausible. Everything fine!!

Great!

[planckkonstante]

Great work thanks!

emcek reported on Discord

"I'm using the gateway with Buderus RC25 and by default the modes available in EMS-ESP are "auto/manual/off" and in reality it's "auto/day/night". Can I adjust that myself somehow or it would need a source code change?"

Looks like we need to adjust this as well

[proddy]

I've added it to v3.4, needs testing though
