Hello, thank you for this useful project, I have been using it for many years to read sensor data from Tasmota and Espurna sensors.
I have the following problem: I have a tasmota device which sends a sensor reading with a field that contains the reserved character .:
2023-12-02 13:20:52,756 DEBUG: mqtt_on_message tele/tasmota/tasmota_16268C/SENSOR b'{"Time":"2023-12-02T14:20:52","VINDRIKTNING":{"PM2.5":5}}'
2023-12-02 13:20:52,757 WARNING: different number of fields
2023-12-02 13:20:52,758 WARNING: empty fields
I am interested in transporting the value of field PM2.5 to influxdb, my config.yaml is the following:
- measurement: pmtwodotfive
topic: tele/tasmota/+/SENSOR
fields:
value: $.payload.VINDRIKTNING.'PM2.5'
tags:
id: $.topic[2]
How should I properly declare the path of .payload.VINDRIKTNING.PM2.5? The above configuration is not working for me.
If I am understanding the documentation of jsonpath-ng correctly, single or double quotes should be sufficient to select a field with special characters:
| Syntax |
Meaning |
| fieldname |
the field fieldname (from the “current” object) |
| "fieldname" |
same as above, for allowing special characters in the fieldname |
| 'fieldname' |
ditto |
