TB w/ Shelly EM Integration
Shelly Gen 1 設備，感測端回傳數值分別有各自相對應 topic，連同感測數值，不符合 TB telemetry JSON 格式 (key: value)。
When configured for MQTT Shelly EM reports data on:
shellies/shellyem-<deviceid>/emeter/<i>/pf power factorshellies/shellyem-<deviceid>/emeter/<i>/power instantaneous active power in Wattsshellies/shellyem-<deviceid>/emeter/<i>/reactive_power instantaneous reactive power in Wattsshellies/shellyem-<deviceid>/emeter/<i>/total total energy in Wh (accumulated in device's non-volatile memory)shellies/shellyem-<deviceid>/emeter/<i>/total_returned total energy returned to the grid in Wh (accumulated in device's non-volatile memory)shellies/shellyem-<deviceid>/emeter/<i>/voltage grid voltage in Volts
要讓 Shelly EM，透過 MQTT，回傳感測數值至 TB，其一解法詳見本文。

Shellies
Shelly EM
- shellies/+/emter/0/+ (or shellies/+/emter/1/+)
or if we configured a custom prefix in the device settings: shellies/(custom_prefix)/(device_name)/#
- Try using software such as mqtt explorer to listen in on your mqtt broker.
It helps you determine which messages are being sent, and the topics on which they are broadcasted.
- Connect Shelly EM to Mosquitto Broker (allow_anonymous true)
