RemoteIO and Modbus serial-TCP gateway: read serial Modbus devices over TCP

[@SeaTaj]

Great video. This is the perfect type of nerdy content for me!

Good job, Thank you for your work and info.

Hi Thanks for the help, it got me started. I struggled to get the inputs working with address 1 and assumed it was because i had multipole hubs, turns out the analogue inputs need to start at address 100 for integers and 200 for floating point.

I also use the EBYTE modules. When would you use MOD-TCP and when MQTT? Both are possible to send your data to HA. Any ideas?

[@csongorvarga]

Good question. I would rather use Modbus, as you can communicate with the module directly without any additional software stack in the middle. Buy you have to configure everything manually in the yaml. With MQTT the entities get detected automatically in HA which is nice.

Thanks very useful video. Could you show how to use range 4-20ma sensor to get absolute values in HA. For example (pressure sensor) 4ma - 0 bar, 20ma - 12 bar???

[@csongorvarga]

Unforunately this is where my Home Assistant knowledge ends. ESPHome has a similar yaml file as the HA config, and it is possible to define a simple mapping. Maybe you can add the same to the HA yaml as well: filters: - calibrate_linear: - 1262 -> 6.88 - 1486 -> 9.22

Hello, great video!!! One question, can you view the history of for example the temperatures in Home Assistant and can you export this or download the data?

[@csongorvarga]

I am not a HA expert, but I remember seeing history graph when I last played around with HA.

[@Bij-en-iot]

Yes, that's possible

Hello, how did you change the AI ​​range to 4-20mA ?

[@csongorvarga]

Check the documentation: Holdig Register 0x04B2 stores the sampling range 0 for 0-20mA and 1 for 4-20mA

@@csongorvarga Thank you for your answer, I already changed thanks to your video. I can't find the "water tank" icon in my Home Assistant or in the directory, where did you get it?

[@csongorvarga]

@@arkadiuszbaczek804 I only defined in the YAML file that it is a class volume and HA picked the icon automatically. I did not change that.
