I have it set up with Alexa which makes life easier. The app does need to be updated so that all buttons are tagged properly so that they read with VoiceOver. I received an email to say that there will be an update to resolve the issues with the new Alexa plus?? Hope this happens soon. ### 5/5 — Brilliantly Simple to setup and use :) *2025-05-28, version 2.4.0* Wonderful App for a brilliant System, of all the systems I’ve used, this App and the EPH controls seem to work great together. Thanks for making this Great little utility :) ### 3/5 — Issues with all *2025-03-09, version 2.4.0* Why is my app showing temps like 20.8 instead of 21 or 20.5? Tx, C ### 3/5 — Good system, irritating problem *2025-01-19, version 2.4.0* The system itself works well but as already highlighted and not fixed, you can adjust the temperature in app but it can take several attempts for the change to take effect. Change the temperature to a new value then seconds later it usually reverts back to the original setting. Annoying if it looks to have worked but then the heating is on all night because it’s reverted. ### 5/5 — Fantastic support *2024-10-23, version 2.4.0* Not quite as intuitive as some systems but much easier & less expensive to retro fit to my heating system than putting in a whole new control system. The phone support is fantastic…Greg is a legend! Initial support for my ineptitude and then when there was an issue with my network…thank you! ### 5/5 — Great support *2024-07-26, version 2.4.0* I love this app for my heating. Occasionally I need a bit of help to reconnect thermostats to the programmer etc but they could not be more responsive or helpful esp Patrick 🙌🏻 ### 5/5 — Technical assistance- absolutely brilliant!! *2024-07-19, version 2.4.0* I was forced to change the faulty router at our home. In doing so I messed up the resetting procedure and finished up with zero heat and hot water!! I phoned the technical support team and was immediately answered by Terry who was so polite and helpful - he assured me that he would be able to talk me through the process to reset the system. I cannot put into words the patience and understanding he had by successfully rectifying our system. Terry you went beyond the boundaries for help - many many thanks once again. George & Heather ### 5/5 — Pairing after change of internet provider *2024-06-28, version 2.4.0* I was given very helpful advice by email. I got stuck and phoned EPH/ EMBER for technical support. Engineer rang me back and walked me through the process which included a workaround for my particular Eero router. Very patient with me and system successfully pairs. All working perfectly again. Very happy with tech support ### 2/5 — poor *2023-12-24, version 2.3.0* First time away from home trying to control the heating this evening and I get “Socket error” when trying to change the mode. That’s not a very user friendly, helpful or descriptive error is it? What’s worse is temperature changes don’t actually take affect, but they appear to. The activity log shows the temperature change as “temperature error” so it clearly didn’t successfully send the command to the boiler but it would be impossible to tell from the UI since the temperature change looks to take effect, there’s no immediate alert. Even the “on/off” animation is clearly written to be purely client side and not an actual indication that the boiler has received instruction to turn on and is actually on. At least when the mode change errors I’m told with an alert even if it’s a completely non user-friendly error message. Your temperature change error doesn’t even alert. What exception encompasses a socket error? Why can’t you give me instructions on what might fix it? I tried the obviously like changing network etc, does my device need to restart? Maybe my device should be capable of auto restarting if it can’t reach out to something like 8.8.8.8 or whatever… ### 3/5 — Could be improved *2023-12-14, version 2.3.0* The app does what it needs to - I can control the heating from my phone. However a lot of the time when you change the temperature, two seconds later it flips back as the change hasn’t taken effect. So you’ll turn it down to go to bed and not realise it’s still on. This should be fixed ideally by ensuring the correct temperature is set even when the app has been closed via a background process, without requiring you to reset the temperature as many times as it takes for the controller to receive the change. Also there’s no home/siri integration. ### 4/5 — Use on computer *2023-10-03, version 2.2.2* Works fine on my 14" M1 Macbook Pro. ## Most critical reviews (10 lowest-rated) ### 1/5 — DOES’NT WORK OUTSIDE HOME TIME ZONE *2026-01-23* Major design flaw in the app that must be addressed immediately. The app is rendered useless outside home time zone. If you are in a different time zone…eg: home in IRL, you’re in the US…you can’t use any function on the app. No boost, no changing times, nothing!!! FRUSTRATING!!! ### 1/5 — Poor *2025-10-19, version 2.4.0* Connected everything via instructions only works once or twice then nothing wish I would of bought hive ### 1/5 — Not good enough *2025-03-08, version 2.4.0* For such simple functions that this app has to carry out, it was incredibly poor. The owners of the app need to invest in improving it. It can take multiple attempts to actually make changes take effect and often it just randomly restores old settings. Extremely frustrating - these glitches have negative environmental impacts (running heat or water unintentionally) and costs users money. I would not recommend. ### 1/5 — Unexpectedly stopped working *2024-11-30, version 2.4.0* App suddenly stopped working and connecting to my heating and I can no longer control my heating . No one seems to be able to help ### 1/5 — Poor & unreliable *2024-06-05, version 2.3.0* Socket error all the time when away from the house. Not great when you work away. Trying to save money and CO2 and this app lets me down all the time. App works in the house, but didn’t need to pay for that. So disappointed. ### 1/5 — Don’t change your broadband supplier! *2023-12-05, version 2.3.0* Great when it works almost impossible to reconnect…. Use a different make. ### 1/5 — Consistently unreliable *2023-08-25, version 2.2.2* Endless problems with it. Sometime it works quickly. Sometimes it doesn’t work at all. Sometimes it takes ages to recognise a command. Hopelessly inconsistent. ### 1/5 — Set up cumbersome *2022-12-13* Set up was cumbersome and they kept asking for more info. When they wanted my WI-FI password, I deleted the app. Ember Cup works great without the app. ### 1/5 — Doesn’t work half the time!!! *2022-11-16, version 2.2.1* Half the time this app doesn’t work it either says ‘Network Error’ when there is absolutely no issues with WiFi and all lights functioning correctly, or it will let you turn on your heating and tell you that your heating is on but when you get home you find that it hasn’t even come on!! Cannot rely on the app so I just have to turn use the manual heating controls as this app is too unreliable. ### 1/5 — Useless *2022-03-02, version 2.1.5* Can’t even get into the app because it won’t send me the email to verify my account. Tried multiple times and uninstalled and reinstalled the app but still no joy. ## Most praised reviews (10 highest-rated) ### 5/5 — Fantastic ! *2026-07-02, version 2.4.0* Great looking app and super easy to use. Would definitely recommend ### 5/5 — EPH Controls *2026-07-02, version 2.4.0* Highly recommend this App very simple to use. ### 5/5 — Great app, great customer service *2026-07-02, version 2.4.0* Started using as replacement to another smart stat app. ### 5/5 — Homeowner *2026-07-02, version 2.4.0* Great App, easy to navigate. Simple control of my UFH, upstairs radiators and hot water. ### 5/5 — Simple, quick, great tech support *2026-07-02, version 2.4.0* Such a brilliant service from EPH. The APP is easy to navigate and simple to use. When I have needed help, technical are friendly and very knowledgeable. Thank you. ### 5/5 — Great Product *2026-07-02, version 2.4.0* Easy to set up and very user friendly app, have recommended to friends and neighbours on a number of occasions ### 5/5 — Brilliant solution *2026-02-14, version 2.4.0* I have a Tado X system for my radiators. Unfortunately Tado only provide basic On/Off switching for hot water so last year I bought the EPH-HW-OT programmer and wireless thermostat for my cylinder. Tado still turns it on and off once a day but EPH provides granular control and allows me to see and set temperatures easily. Even before adding the Gateway EPH support was brilliant. I just added the GW04 gateway (nervous as GW03 is specified) and installed the app. Again with amazing support to set the wireless thermostat transmitter in hub mode and I was quickly up and running. I expected to just monitor temperatures but I can actually do all the programming I need in the app. I would give 6 stars if I could. ### 5/5 — Tech support *2026-02-13, version 2.4.0* Excellent technical support provided by Terry - extremely helpful and patient when sorting out my technical issue. ### 5/5 — Andrew *2026-01-13, version 2.4.0* I recommend not only the product but the exemplary customer support team who are amazingly helpful and will walk you through any questions or issues you need resolving. Everyone you deal with is extremely knowledgable and helpful. ### 5/5 — Reconnecting to app *2025-11-19, version 2.4.0* Due to user error i lost connection between my controller and the app. After much pulling out of hair i rang NPH and got a very helpful support person who talked me through the entire process in very easy steps. Now working again. Overall excellent kit we have had the system for about 6 months and are very pleased. Would definitely recommend the kit and the app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
