Hi, I've used the service since 2018 and I'm very happy with it. In these days I've added some sensors (Shelly) to my project and I'm trying to switch to MQTT since they suppport it: I've configured all for ThingS. side and tried to send data via MQTT with a manual client to see if it runs. Done. It runs. The problem is that Shelly sensors use their specifi topics: shellies/shellyem-<deviceid>/emeter/<i>/energy energy counter in Watt-minute shellies/shellyem-<deviceid>/emeter/<i>/returned_energy energy returned to the grid in Watt-minute shellies/shellyem-<deviceid>/emeter/<i>/total total energy in Wh (accumulated in device's non-volatile memory) shellies/shellyem-<deviceid>/emeter/<i>/power instantaneous active power in Watts shellies/shellyem-<deviceid>/emeter/<i>/reactive_power instantaneous reactive power in Watts shellies/shellyem-<deviceid>/emeter/<i>/voltage grid voltage in Volts shellies/shellyem-<deviceid>/emeter/<i>/pf power factor (dimensionless) shellies/shellyem-<deviceid>/relay/0 reports status: on, off or overpower and, as I can see, they could not been changed. On the other side, ThingS has his own topic stucture: channels/619092/publish/fields/field1 Is there a way by ThingsSpeak side to "translate" or "bridge" or something else 1 topic to another one? Any idea would be appreciated.
