### 1/5 — Connect

*2026-07-06, version 7.29.1*

It is such a pain to get everything to connect, once it’s sorted it’s great, untill a June update, no connection, phone app can’t even find the thermostat, absolute nightmare

### 1/5 — Doesn’t connect

*2026-06-23, version 7.23.8*

No longer connecting after app update. Real shame.

### 4/5 — Works great once connected.

*2025-12-23, version 7.21.7*

OK, so to have to turn off 5ghz WiFi, turn off cell service on phone, say a magic chant, stand on head and juggle with your eyes closed seems a bit extreme, but once the app and thermostat were all connected it works really well! But seriously, the WiFi and cell service did need turning off, but once everything was connected the app itself if really quite good, and I’ve used Hive for years before that. Integration with Alexa also works really well, and even turning off or rebooting the WiFi (and, yes, you can turn on 5ghz once everything is connected the first time), causes no subsequent problems when everything has restarted. Pleasantly surprised!

### 1/5 — Shockingly poor, basic and broken

*2025-11-18, version 7.21.7*

I'm not sure why ESI bothered to add WiFi to their products if this is the best that they can do for an app.

Bare bones, barely works and sometimes not at all, can't even rename devices so it's impossible to tell what you are controlling.

Who signed this off, who at ESI is happy with this??

### 1/5 — Reasonably poor

*2025-11-03, version 7.21.7*

If the setup needs permissions (I’ve just provided it with the information it says it needs access to manually, but it refuses to use it) then why not either ask for it at the outset, or lead the user to the setting required. Much more difficult to use than it needs to be.

### 1/5 — So difficult to set up

*2025-10-28, version 7.21.7*

I had a Hive before and it took about 15 mins to set up and get working. This setup of an ERTP4 controller and WiFi hub requires the invocation of dark spirits to get working. I followed the instructions religiously to add devices to the app and I could not get it to work. Watched YouTube vids and read instructions from product web site. Gave up and called the plumber who had installed it and he asked around. I eventually went back into the app and it had suddenly started working! Unfortunately, I accidentally deleted the device and had similar issues getting it working again. I now have 2 devices for each device and cannot delete the offline ones without deleting the working ones. I am going to limp along with both as I’m not going through the pain again!

### 5/5 — Quick and simple

*2025-10-08, version 7.21.7*

Works perfectly fine.  Can schedule date and time to set the thermostat.

### 1/5 — GHz 2.4 only

*2025-03-24, version 7.18.1*

Will not connect to WiFi

### 4/5 — Frustrating setup

*2025-03-15, version 7.18.1*

Took me a while to connect with my thermostat because the instructions didn’t match completely. 

There’s a little WiFi indicator on the thermostat to indicate if it’s connected to the hub. I was waiting for the blinking to stop and pressing all day, holiday and plus multiple times even though it was already connected. 

The other issue was on my Virgin router I had to go into router settings and turn off 5Ghz mode in order for my phone to setup the hub on the wifi network. Which I think a lot of people would struggle with.

Other than that seems to be working fine now. Big improvement for a fraction of the cost of Hive.

### 4/5 — Decent app, please keep adding quality of life features

*2025-02-10, version 7.18.1*

Only had one hiccup to start with where the request to access WiFi options was not being triggered and as a result set up got stuck. Re-installed the app and it was ok second time.

Would love to have the option for a 15/30 minute boost on heating 👍

Please keep taking feedback and adding simple improvements like that.

Otherwise the basic functionality is generally good.
