The best wired module for inputs and outputs (IO)

Hardware
1

Hello,

One of the most important things when selecting components for selecting a home automation system is the input / output module to control various components. I would like wired modules with popular communication (example ModBus TCP) that are easily available on the market. Modules must have transistor outputs.

My example of modules: DirectIndustry

Can anyone recommend something?

Thank you

Moxa is pretty ok, but expensive :thinking:
The company I work for are using them, and they can do mqtt straight out of the box

A much cheaper option would be ESPHome, thet can do digital and analog IO and also serial com…
Major advantage is thet are only €2-3
However, it does involve some DIY😋

I work with the Ukrainian startup i3 Engineering, they have interesting controllers based on ESP32 with a large number of inputs (up to 22) and outputs (up to 30). Works well with ESPHome.

I find something like that:
Weidmueller UR20-FBC-MOD-TCP-V2
This is a main module, not cheap but additional input/output modules have good price.

  • in large system have good price
  • avaible on market
  • it`s made for industry

What do you think ?

Hi okozak
Do it have to be the ESP32 version to connect to Home Assistant?

Hi! There are 2 types of controllers: STM32 and ESP32.
STM32 version has its own firmware, and integrates with HA via mqtt.
For ESP32 controllers you can create esphome or tasmota firmware.
Both of these versions are available.
If you write to me what needs to be controlled, I will help you choose a controller model.
