Terma BlueLine Next

We purchased the heating element solely for the feature of Bluetooth connectivity and being able to control via the app / set schedules. No matter how close you are to the device, it never wants to pair on the app or when you have finally paired… it then states you’re “out of range” so can make no further updates. They need significant improvement given how much they cost. No end of frustration.

So much worse than the original app, which is in itself very unreliable. This app makes Bluetooth connection extremely frustrating, it works so rarely. Pairing devices takes forever with multiple failures. Even the language used when you finally make things work is lazy. Schedules are sometimes called schedules and sometimes Harmonograms which adds to the confusion. Please please bring back version 1 or even better an improved version of version 1 before I break my phone by throwing it across the bathroom in frustration. I have 4 towel rail heaters and setting them is taking over my life!!

Awful app, far worse than the first one. Completely useless. Every time I want to change a setting, it takes hours of battling to connect with my radiators to update them, despite my phone being right next to the elements. It is nearly useless with the older version of the heating element (the ones without the external sensor). Guess that was Terma’s plan, to force people to spend more upgrading heading elements. Why not design a WiFi enabled heating element that actually works!

Fails to pair the heater after multiple attempts.

After finally managing to connect to the heater, I then tried to change the schedule to a higher temperature, it looks like on the app it’s been done. But in reality nothing…. Heater only comes on when manually pressing button on the heater. One of the worst apps come across!

Had the same problems as others of not being able to connect to the heaters or being able to upload a schedule. I’ve now found the app works as it should as long as you are holding your phone RIGHT next to the Bluetooth element on the heater!

The so doesn’t work, will not respond to touch. Heater Bluetooth will not pair to iPhone. Complained to Screwfix - now waiting for Terma technical support!!!

Why design this thing to communicate via Bluetooth? Even when it’s working, which is not often, I get “Device out of range” when I try to use the app downstairs to control the radiator upstairs. I have to go half way up the stairs to get within Bluetooth range. Why not design it to work over WiFi which is much stronger throughout the house? The whole thing is an utter shambles, frequently losing connection, needing to be unpaired and re-paired. Its latest trick is to refuse to pair, despite following the instructions to the letter. Great. So now I can only use the heater as a manual device, the app does nothing at all. I’ve unpaired, re-paired, deleted, reinstalled and updated the app all to no avail. Underdeveloped junk. I loathe it.

If you are offering a radiator with a Bluetooth option, then the Bluetooth option should be readily up and running. This is basically a radiator with an on/off button as it stands, as the app is awful and does not work, making the Bluetooth in this redundant. Sort it out!

The app works to control our towel rads, but a couple of things just really wind me up with this app. e.g. 1) Despite schedules being called “schedules” at the bottom tab, they’re referred to as “harmonogram” in the dropdown. Why?! 2) Setting a timer via Bluetooth: the default option is to turn off after the timer is finished when it would be better if it reverted back to the programmed schedule.
