OpenHAB3 transformation not working

I used to have OpenHAB2.5 working correctly when I decided to update to v 3. I did a clean install, not upgrade in any way. Mosquitto MQTT is configured and payload does received, however, there is some error with data transformation that was working earlier correctly.
Karaf console log :
11:26:06.125 [WARN ] [hab.binding.mqtt.generic.ChannelState] - Incoming payload ‘{“timeStampUTC”:“10:18:49”,“temp”:“8.10”,“hum”:“87.80”,“abshum”:“7.30”}’ not supported by type ‘NumberValue’
11:26:06.147 [WARN ] [tt.generic.ChannelStateTransformation] - Transformation service JSONPATH for pattern $.hum not found!

I set channel data type to Number and incoming transformation as JSONPATH:$.temp as it was configured earlier.

Has syntax changed in OpenHAB3 or what is wrong here ?

You don’t have the JSONPATH Transformation Service installed.

See step 6 here on how to install.

OMG, indeed :slight_smile:
