If you were making what you asked for, you could call it divide100.js for example, but its up to you.

Ive no idea if you can use PaperUI to edit text files, I doubt it.

I dont find examples for Modbus v.2, but offen I finded example only modbus v1.

Guessing you are using PaperUI, find the read transform box and put in it.

The JS parts tells openHAB its javascript, because there are several types of transformations.

Whether the bridge Thing that owns them is TCP or RTU makes no difference at all to them.

You set up a serial bridge Thing for RTU or a tcp bridge Thing for TCP.

Domoticz Modbus Universal Rtu Sdm120C Manual Call Point

I have installed Modbus binding and I am working to control smoke Detector and Manual Call Point using modbus protocol.

I have configured Modbus 2 in Paper UI and I am getting some issue.

I have configured things, items in.things.items file.

Still I need configure same in Paper UI.

When I has written files.things,.items, sitemap I saw all it in PaperUI.

By the way site Openhab dont work in Russia, I need use VPN for it.

I create scetch as arduino slave and I ran OPC modbus programm in my PC and I recieve data from modbus.

As you already have a serial setup, make sure your Arduino uses the same serial settings as the solar thingy.

You cannot successfully have devices with different baud or parity on the same wired bus.

If you want help with openHAB, youre going to have to share your setup details and things like messages in openhab.log.
