How to integrate HA with an I2C relay board without ESPHome?
There is relay board on XL9535 chip with I2C interface, for example https://www.aliexpress.us/item/3256805588736472.html
- GPIO integration was removed (including SPI and I2C)
- Integration through ESPHome Xl9535 integration
I’d like to understand is it possible to integrate HA with I2C devices without ESPHome?
