Q2 If i4 is not supported by ESPHome, what hardware running off 240VAC will provide 4+ binary inputs?
Q3 Are all ESP32 devices supported by ESPHome?
Assuming one can flash the firmware over UART, are all ESP32 devices supported?
Are all Shelly ESP devices supported??
Everything based on esp8266 or esp32 is technically supported. The questionable are modules with extra chip inside, like sensor, measurement chip… THAT’S when you have to ask yourself if it is supported, since not all special chips are supported.
In your case shelly i4 only contains 4 inputs and nothing else. The only question is to find gpio’s of where relays are connected to, but even this is not the problem…
Please see this example, as long as you have a monetary switch or the shelly wall buttons you can flash esphome on the i4 using the serial header pins, make sure your i4 is “OUT” of AC wiring as the GPIO pins are connected to the AC side and will fry any USB TTL adaptors while attempting to flash in circuit: -

if you have the right adaptors for flashing all should work nicely: -
As other esp32 shelly modules are supported I cannot see why we cannot put esphome on the shelly i4, at least it’s on blakadders site, the issue is no one has posted online a working example apart from @adorobis
Thanks for sharing my example. Just keep in mind I have not flashed i4 with esphome. I use it as is with standard HA integration. I have esphome on another module to control the gate input and get additional reed switch for gate close sensor.
Correct. But as my gate is controlled with one input only (step-by-step) I’ve added the Shelly i4 to get information about the motors: if and in which direction they are moving, so in HA I can better control the gate - this is done with a template cover in HA taking inputs from i4, esphome module and controling the relay on esphome accordingly.
