Professional device for controlling OC outputs via telephone/tablet

Welcome.

I'm looking for a professional device to control the outputs via phone, tablet. For the client, the most important thing is that the visualisation looks nice (icons changing colour, etc), what sits inside does not matter. It has to be solid and proven hardware, failure-free as much as possible, install and forget. I have a few ideas:
- Raspberry Pi, but I associate this device with a toy, not to be locked up somewhere e.g. in a factory.... well, unless I'm wrong.
- control panel, but visualisation is out of the question, as you only need buttons and output states.... and I don't know if it is possible to truncate the visualisation to just that,
- pLC seems ideal, but it is form over content. On the other hand unlimited possibilities, visualisation in html5,

Maybe you know of some devices between the Raspberry and the PLC, allowing the user a simple and convenient control?

Thanks in advance for your interest and help.

Maybe some professional drivers based on the Raspberry Compute Module:
- Pigeon ,
- Modberry .
Both products Polish.

How about a microcontroller of some kind? The simplest would be an Arduino, or a regular ATmega and Ethernet Shield, if you need a bit more power, then some STM32. Nucleo boards have the possibility of connecting modules dedicated for Arduino, so the mentioned shield could also be used.

And you might be tempted to make an Android app to control everything. You could use for example App Inventor: Link . It may be a bit clunky and applications are not efficient with it, but it should suffice.

Thanks, the equipment looks cool. What if the number of outputs increased and you needed 30 pieces?

if adding inputs to the raspberry is a problem for you or you rule out such a solution, then head straight for Wago.

In this situation you can use any I/O modules with RS-485, Ethernet, CAN interface. For example, the ADAM-4000 series.

Or simply I/O modules that communicate over SPI, or I2C. For example, the PCF8574. There are even ready-made boards with this chip. It's a much cheaper solution than the ADAM, although obviously less versatile.

Another option is to use multiple microcontrollers as extensions.

Please provide a link to PROFESSIONAL input/output modules communicating over SPI or I2C.

Ok, thanks to everyone. The choice fell on the Wago plc.
