Pros
Pro Automatic location based control
Based on your location, the Tado thermostat can automatically determine when it needs to be on and when it can stay in idle mode saving power. This location data isn't monitored by a motion sensor - instead it uses your phone's location so that by the time you arrive home it should already be a suitable temperature.
Cons
Con Requires a hub to be plugged into your router
You will need to use the hub, which is another piece of equipment in your house. It also needs to be plugged directly into the router which means one less available port on the router.
The requirement of the hub means that the range is limited, which could mean that the thermostat has connection issues depending on where it's installed (walls or far distances will lessen the signal strength).
Con Installation is very tough
Tado suggests you get the wiring done professionally. While it's convenient that there is a conversation between you and Tado to figure things out ahead of time - making sure the installation itself goes well - it's inconvenient that you need to have it set up professionally when the other major thermostats can usually be wired with relative ease.
