I use Gosund SP112. Available at Amazon, ~12€ / plug. Flashable with Tasmota or ESPHome (I use the later). It can switch the mains as well as one USB-A power outlet. You need to open it to flash it the 1st time. There's at least one unused accessible GPIO. On one I soldered an DS18x20 temperature sensor. Now it controls the heating in my shed based on the measured temperature stay above zero degrees in the winter.
