A small tool to add every Modus/TCP device to Homey

Modbus

Connect every Modbus devices

This tool allows to add any Modbus/TCP device to Homey without a specific app.
You can read and write Modbus register with flows.

How to start?

Add a device. Insert the Modbus details of your device including IP address, port and Modbus device ID.

The Homey device doesn’t offer functionality. It only connects to your Modbus device.

How to read/write register?

Create a flow and use the dvice flow actions to read a register.

Use the second flow action to write a register.

Be careful! Use the manufacture Modbus reference.
Change only those registers for which the meaning is known.
Read the register before and remember it’s value to be able to reset the value to a default value.

A description and a use case reading and writing register of a Fronius inverter is available on my Homepage:
