Multifunctional smart home controller Atom on ESP32

what exactly are the switches you use? Is it difficult to make them work at 5V?

22

All the functions you are talking about will work in these devices - pulses for switching relays, and display of the included lamps in HA. But the inputs of the controllers are designed for a voltage of not more than 5V. Moreover, you can connect many different sensors (even DS18B20), assign different scenarios to a single, double, long press the switch. You can configure the WS2812 pixels

Hey,

It’s easy to change the switches to 5V, so that’s not a problem. I use the switches as an alternative if my home assistant would fail.

Which device would be best suited? As I need 64 inputs/outputs.

I think the following 3 controllers would be best for you:

But they should not be connected to the outputs of very powerful lights

You could use a generic ESP32 with I/O expansion via the I2C bus.

Yes, on ESP32 this is the best option. It can be implemented as a constructor (ESP board and expansion card), or as a ready-made controller. Here is a photo of how the controller looks without a case (22 inputs, 30 outputs):
