As above. What's the purpose?
I haven’t seen this before. Are you using a beta version of the app? Currently everything goes via the cloud, but perhaps Tado are taking steps to introduce the much needed local comms. Or perhaps they want to see what other gadgets are used in the home.
Its like those phone apps that are ultra invasive and request access to your phones camera and mic when they don't even use those features in the app itself...
Is this a compulsory access you need to provide for the tado app to work? I would definitely NOT want to allow free reign access to my home network and personal devices.
