Shelly addon - more than temperature?

Is it possble to make a Humidity sensor comatible with the GPIO adapter in the Temperature Sensor Addon for Shelly 1/1PM package?

Maybe Shelly has plans to sell a Humidity sensor that is compatible with the GPIO-adapter in Temperature Sensor Addon for Shelly 1/1PM?

If not, can you tell me if it is possible to connect any other compatible a Humidity sensor to the Shelly 1PM similar to how you can connect your recently announced Temperature Sensor Addon?

The reason that I ask is that I have a (dumb) dehumidifier and been wanting to make smart and was wondering if could manage to do so with only a single all-in-one Shelly power-switch product that would support both electricity consumption measurement like the Shelly 1PM as well as be able to via its GPIO ports directly connect a humidity sensor like the Si7021 or AM2301 sensors which are for example sold by Itead for their Sonoff TH series.

I know that would probably not work out-of-the-box your current version of firmware on the Shelly 1PM but could I maybe connect a Si7021 or AM2301 sensor to a Shelly 1PM and use third-party firmware like Tosmota?

Sure I could use a Shelly 1PM and the separate wireless Humidity sensor and automate it, but I think that having humidity (and temperature) sensor like Si7021 or AM2301 directly wired to the board of a Shelly 1PM would make a nicer integrated product.
