Temperature sensor TFA Dostmann 433mhz - Rfxtrx - Event is not JSON serializable

Configuration
1

Hello,

Im trying to read the Temperature sensor TFA Dostmann 433mhz with Home assistant trough Rfxcomxl.

But Home assistant receives the pulse but it can’t translate the data:

Logger: homeassistant.components.recorder.core
Source: components/recorder/core.py:620
Integration: Recorder
First occurred: 8:49:56 PM (2 occurrences)
Last logged: 8:49:56 PM* Event is not JSON serializable: <Event rfxtrx_event[L]: packet_type=3, sub_type=12, type_string=nec, id_string=Undecoded, data=05030c000700, values=Payload=bytearray(b’\x07\x00’)>: Type is not JSON serializable: bytearray

Looks like it can’t read the “bytearray”?

I suppose this sensor is not in the list of supported sensors, see the RFXtrx User Guide chapter 2.

Disable “undec on” as this can not be used in HA

Packettype = UNDECODED RF Message
UNDECODED NEC:0700

Thank you for the reply and pointing me to the user guide where is was not aware of.

TFA type is in the list of supported protocols;

It is a “lacrosse” protocol a parentally, what is supported bij HA. “lacrosse” is also mentioned in the firmware update of last month.

FW release 433_1046 12-07-2022
LaCrosse WS1652 added in Pro2, ProXL1

Ill try to update the rfxcom first.

After updating the Rfxcom it works with the lacrosse protocol :+1:

Well see how long the battery will last. There are 2 AA in there so probably a long time.
