Hitemp is an app which enables smart remote control of heat pump water heaters. It uses email and verification code for registration. In this case, the units will be bound to the app by scanning the bar code on the units. Then users are able to control the units through networks, including startup & shutdown, temperature setting, mode switching and so on. Meanwhile, it can record the operation status of the units constantly, and alarm in time when certain faults happen to the units. ## Key features - Remote startup & shutdown - Temperature setting - Mode switching - Operation status recording - Fault alarms ## Recent user reviews (10 of 16) All indexed reviews: https://appshunter.io/ios/app/hitemp/id1512533849/reviews.md ### 1/5 — Bug in new update? *2026-07-30, version 1.3.1* The update doesn’t show anymore temperature data, it stopped immediately after update 👹 ### 1/5 — What a waste of time and money *2026-07-29, version 1.3.1* Completely Pathetic ### 1/5 — Upgrade fail *2026-07-29, version 1.3.1* Unfortunately my system has forced an upgrade. Now the App is permanently Offline - even after re-installing as per the manual. The Temp curves are visible, but it still states offline. ### 3/5 — Off line *2026-07-28, version 1.3.1* The app stull saiing the module is offline…. Before i didn’t have this problem ### 1/5 — Really bad *2025-10-06, version 1.2.9* Always thought it wasn’t up-to-scratch, and now with app consistently crashing out whenever accessing temperature curve, I’ve got to give it two thumbs down ### 2/5 — Yep, it’s pretty bad. *2025-06-05, version 1.2.8* Can remotely turn the Evoheat off and on, so not completely useless. But as per other reviews, temp curve is 12 hours out from actual time. Vacation Mode doesn’t seem to work at all as it just ignores the date to come back on and just stays off. Evoheat should find a new App to partner with as, given all the reviews that seem to be ignored, the app developers of Hitemp clearly have no idea or just don’t care. OMG! It gets worse. After having to manually switch off Vacation mode, it’s impossible to turn off the electric booster. I switch it off in the app and watch as 30 seconds later it gets switched back on. I’ve done it 30 times now and it refuses to stay off. Aaaarrrrgghhh. ### 2/5 — Crashing *2024-01-08, version 1.1.9* Always crashing while trying to get into temp curve. ### 2/5 — Crashing again *2024-01-02, version 1.1.9* Worked for a while but is now crashing again when trying to get into Temp Curve. ### 1/5 — Ok but keeps logging out *2023-10-05, version 1.1.6* App seems to function ok. But it keeps on logging out. You have to enter your password every time to use this app. the support for the app seems to only be in Japanese. ### 1/5 — Can’t even report what wrong to the app creator *2023-08-26, version 1.1.6* Reporting problems is impossible unless you can read and know Chinese The bug reporting is not in English ## Frequently asked questions about Hitemp ### How do I connect my heat pump water heater to Hitemp?
