For convection heater - app displays extremely small size numbers for the "current" temperature while "set" temperature has huge numbers. Madness.
★★★★★Andrew Faulkner· Oct 14, 2024
Just have to set all to manual if using the program side else it always defaults to 21⁰c

Great app and great product. I am using it for over 2 years, very efficient. And I can control temperature, timer etc. from my mobile
★★★★★Darren Kelly· Feb 5, 2026
Ideal interface with equipment, with many different options for timing functions and disabling functions. Still trying to find out how to disable the bleep whenever you do anything on the control panel....
★★★★★Kevin Deasy· Dec 9, 2024
It is the app is not nearly as good as the old app ant too hard to read the small print and to set one off times GO BACK TO THE ORIGINAL APP
★☆☆☆☆Kyle Jenkins· Nov 25, 2024
App only works for remote operating "live". When I add on/off schedules for my Bornholm heaters they stop working completely. Power them off, they work again until the next schedule, then they fail again.

Bornholm electric heater countdown function does not work! Solution - use Smart Life app instead, just switch the radiator on, hold gear symbol few seconds' til it starts to flash and add new device through Smart Life app.

The las update made this app useless for me. Before it, I could see the water temperature live, while the Klansman sous vide stick was warming in up. Also, the remaining time during the cooking process. And there were also recipes to find in the app. Now none of this is in the app anymore. Now it is no more than a remote On/Off switch. 100% downgrade, utterly useless.
