I have installed an Intergas Gateway V3.  
It works fine on the iPhone and iPad.  
When I try to install it on the Homey, I get the message “pairsession\_not\_found”

This happens when you switch apps on your phone, for example to get your password from a password manager. When you switch apps, the pair session expires. Make sure you have everything you need on your clipboard before you start the pairing

Plesse find yourself a v2 model to connect it to Homey.

> (So, this model is impossible to add to Homey)

In the meantime, someone reverse-engineered the Intergas phone app to get the v3 GW to work with Home Assistant using the Intergas cloud connection.

[https://community.home-assistant.io/t/intergas-comfort-touch-with-the-new-gateway-custom-integration/1028408](https://community.home-assistant.io/t/intergas-comfort-touch-with-the-new-gateway-custom-integration/1028408)

So, alternatively, an easy (and quickest) way is to add Home Assistant to the mix.

You can request for Homey support per [Intergas Incomfort app topic](https://community.homey.app/t/app-pro-intergas-incomfort-comfortable-temperatures-in-your-home/13590/73),  
or maybe @smarthomesven is seeing possibilities for a separate Intergas GW v3 app.
