[transform.JSONPath] sum aggregation isn't updated #11756

Open Novanic opened 2 years ago

Novanic commented 2 years ago

I'm trying to sum various values of a json received via MQTT. When the JSON path of the item is "$.intervalDatas[0].channelIntervalDatas[0].averageImportRMSActivePower", everything is working fine and it is updated every 5 minutes (a MQTT message is sent every 5 minutes).

When I try to sum all values of the array with this JSON path expression: "$.sum($.intervalDatas[].channelIntervalDatas[].averageImportRMSActivePower)" it seems to work at first, the correct value is set. But it is never updated. The next MQTT messages have no effect / the item is never updated.

OpenHAB 3.1 is used.

You might search some other transform related issues as the combination of transforms and mqtt are not always straight forward. Sorry not much details :-/
