Control Shelly 1 via Hue (Essentials) Android app

Hello guys,

I just received my first Shelly 1 and wondered if I have decided to quickly since I cannot find any answer to my question.

I know that the Shelly is based on WiFi and is not able to speak ZigBee ootb (or even at all).

However, I have several NodeMCUs (based on ESP8266) in my house that I control via diyHue. So, technically it should be possible to enable a WiFi device to speak ZigBee (or at least make the Hue Android app think that those are ZigBee devices since the diyHue fake bridge running on my NAS tells the app they are).

How is this possible with the Shelly 1? Initially, I was just scanning the Tasmota documentation for 5 minutes before going to bed and ordered a Shelly 1 since I found a section for "ZigBee". But reading it in detail now, I am completely clueless on how to make the Shelly 1 function like a ZigBee switch.

Does anyone have an idea?

To ask the question in a different way: I have an idea how to write my own firmware that is compatible with diyHue. What I don't know is how I can programmatically switch the relay on and off.

In case I write my own firmware, the API commands listed in https://shelly-api-docs.shelly.cloud/#shelly1-shelly1pm will not work anymore, right?

So what function should I use to toggle the relay via my own code?
