Berry-ExtSensor

A Berry example application for including sensors of remote Tasmota controllers.

Motivation

I'm currently dealing with a controller, that is supposed to control a heating cartridge for a boiler.

For safety reasons (boiler temperature sensor) a galvanic isolation is required.

Unfortunately is the 'Shelly Plus 1PM'- Addon not available with Tasmota.

This gave rise to the idea of ​​augmenting a specific device with information from remote sensors.

It should merge the sensor-data

and also the UI-elements

Different Scenes

After start of application without any sensors

After installing of the application

The UI-field 'Message Counter' increments each time a sensor message is received from the external controller.

How to install

Preparation of the external device

• a Shelly Plus 1PM is as external device assumed
• install the UdpBroker-app

Prepare the device to be extended

• upload following files to to the tasmota-controller

  • ExtSensor.app
  • ExtSensor01.be
  • ExtSensor02.be

• Restart the controller

Enable/disable enrichment of the sensor message tele/.../SENSOR

    extSensor.enableSensorMsg=true

If 'enableSensorMsg' is activated then the sensor messages will be extended like

{
	"Time": "2024-01-17T19:27:01",
	"ENERGY": {
		"Period": 0,
		"Total": 14.37,
		"Current": 0,
		"Yesterday": 1.019,
		"Today": 0.56,
		"TotalStartTime": "2023-11-16T17:20:56",
		"ReactivePower": 0,
		"Voltage": 225,
		"ApparentPower": 0,
		"Factor": 0,
		"Power": 0
	}
}    

More Information

Take a look to file ExtSensor02.be and see how

• data are obtained from remote controller
• data are prepared
• data are linked to UI
