Tasmota auto energy monitoring calibrator
Here it is reported the possibility of self-calibrating the new Tasmota plugs.
Requirements
- MQTT Server
- Node-RED connected to MQTT Server.
- A properly calibrated plug according to Tasmota official instructions and connected to the MQTT Server.
- A new plug in the absence of calibrating with Tasmota and connected to the MQTT Server.
Usage
- Import the flow into Node-RED.
- Modify the name of the calibrated and new devices.
- Deploy the flow and wait until it self-calibrates.
