Invalid JSON with Firmware > TRB1_R_00.07.11.2

Hi all,

I’m using a couple TRB143s to fetch MBus data and send it via data to server as JSON over MQTT. This works fine on many TRBs, but with newer firmware I observed changed behaviour:

With firmware TRB1_R_00.07.11.2 and TRB1_R_00.07.11.3 I get invalid JSON where the quotes are missing, e.g. output is…
{“my_mbus”: 6A542F958E642 1736275775}
…instead of the expected:
{“my_mbus”: “6A542F958E642 1736275775”}

All TRBs are configured the same way, I use format set to custom with %data% %timestamp%

Is this a known issue? Any workarounds?

Best regards
Jonathan

Workaround:

Also set custom format in data to server:
{ “my_mbus”: “%my_mbus%”}

Previously, I had this set to JSON which was working for older firmware versions.
