T-Smart 4+

The product is great . The app could be so much more with an update . For example I will mostly use the boost feature but my only default option is 1hr at 60c . I want 2hrs at 70c . But feel it should have the ability to be fully customisable maybe with different times (boost 1, boost 2 etc) like I can with a £5 smart plug from B&M . Sadly returning.

Installation super easy with clear instructions. Pleased to be able to monitor cylinder temperature plus schedule the immersion heater when required. Bought in readiness for gas price increases when cost of electricity ‘might’ be cheaper, who knows!

I did notice a small issue with the app when trying to setup a new heating plan but after quick email to the developer a fix was issued promptly with excellent communications.

Overall, I highly rate this product and would not hesitate to recommend if you like your smart home devices.

Have installed five. All five have been faulty. Four in the same way. Sent three back to Tesla. Have got three back. All three confirmed to be faulty and not have any issue with install. Fitted one of the ones I had back and that broke. Replaced with a wifi fuse spur. The other two I will just be selling on. Dealing with the company was great at first. Second time, things moved slow.

Product has been nothing but a head ache for me. Would advise you wait until they iron out all the problems and come out with a second generation stat.

Maybe I have just been really really unlucky. Lost time, money and energy. disappointing
