Hi Colin,

I also have similar problem. Combining 2 MQTT topics into single measurement.  
InfluxDB Node and Bucket both are only one.

Please check my question here.

> Hello All, Help needed in combining 2 mqtt topics (esp/temperature, esp/humidity) into single InfluxDB bucket. Source is sending DHT22 Sensor data via ESP32 over WiFi then MQTT Broker (Mosquito). Then it is send to NodeRed Dashboard and InfluxDB. I tried a method to use functions before sending to InfluxDB Node. As described in the flow. It creates data in bucket, but I dont know how to find the measurements/data/ Following is the relevant flow code. [ { "id": "f6f2187d.f17ca8"…
