two unknown telegram types

I also wonder why JSON below only mentions device ID 0x21 for MM200, it also has 0x20:

Jul 30 19:39:04 ems-esp - 000+00:00:03.929 D 84: [emsesp] Adding new device MM200 (device ID 0x21, product ID 161, version 29.04)

I suppose you also need raw data for unknown telegram types but I found no way how to enable that.

Two of them with context:

there are many unknown telegrams, either by design because we're not interested in the data they are carrying or we just don't know what they are. Usually, we start with missing data as seen on a gateway, thermostat or boiler and then work backwards figuring out where it's hiding in the EMS messages.

also see https://emsesp.github.io/docs/#/Troubleshooting?id=ems-esp-is-showing-incorrect-values-from-a-specific-device

you can query a specific telegram on a device and see what comes back using the read command

@wrohdewald The ems-bus is slow and it takes some time to fetch all information we need. After

"uptime": "000+00:00:04.325"

the devices are not completly registered. You have to give emsesp more time to gather the information from bus.

If you take a look at the system info you'll find the handlers for each device. The telegrams 0xe6 and 0xea are handled by the boiler, 0x12, 0x2a7 and 0x2a8 by thermostat, these are not unknown after device registration.
0xBF is not handled, but known telegram type, it is used for error messages from devices. These errors are logged by boiler and thermostat and republished with date/time and device-source in the telegrams 0x10, 0x11 and 0x12. We read the 0x10/11/12 and skip the BF.
0x255 from mixer is indeed unknown, your log shows only a single null-byte as data. If you can find out what values are published with this telegram, we can add to the mixer, but for now we do not know what it means.

closing, no response.
