Good data, poor app

As many other reviewers have pointed out, the app is incredibly frustrating. With an Ecodan air source heat pump, you’re able to see the temperatures in multiple parts of the system in the app. However, it’s near impossible to analyse what’s going on. For example, the axis scales are fixed, with no option to zoom in or out. Often the vertical scale range is so large that you can’t see any temporal trends. You’re only able to view sub-hourly data in one hour fixed intervals (why!?). There is no option to query individual data points in a plot, or view tabulated values, or even current values for all parameters being logged. The list could go on. The app really seems like a token effort, and it doesn’t seem like it would take much to vastly improve it.

Stable but limited

Good points:
1. The app works and seems stable.
2. There is some good information available in the module view and reports.
3. Setting changes made on the app reflect on the system.
4. You can make many changes to the system settings from the app.

Improvement items:
1. System changes need to be checked to ensure the changes have been accepted by system.
2. Reporting should have all temp settings in one report - flow, return, room temp, outside temp and be able to be viewed within the jour period, hourly, 7 days etc. otherwise it requires moving between reports to get all temp data - suboptimal.
3. Module view on an iPhone - the back and refresh buttons are so close to the swipe line that often in accessible (out at the top of the module view perhaps?)
4. The app is not that intuitive until you have learnt your way around the system, then it makes sense but is clunky. Ideally having better define and easier access to key settings would be preferable.

Future:
1. A report that assessed current settings compared to an optimum configuration would be ideal. Think how Mitsubishi would benefit if it assessed individual / regional / global ecodan data and could provide a suggested ideal, energy efficient optimum configuration (including the potential energy that could be saved), that a user could simply tailor based on their local situation / needs?
2. Needs to be compatible with all ‘now’ standard smart interfaces (HomeKit, Alexa etc etc)

Not great

Setting of timer controls are hard and do not change as they should. For example heating to 17 degrees from 22:00. Yet at 22:30 heating still trying to get to 20 degrees! Have to use manual overrides currently from app - which do work.

Thank you for your recent response- bear in mind I paid £11k for the system and the £150 for the WiFi module/app.

The app is pretty much useless, (I will contact you through as requested but for others buying the system.)

The heat-pump is AWESOME but do not spend the extra on the WiFi module. The app is appalling and not of the same quality as the heating system (thankfully).

Problems include:

- Highly non-intuitive interface,
- The system must be connected to WiFi at all times or your heating will fail,
- No geo-fencing for switch on/off,
- Reporting that doesn’t remember any settings,
- The app is designed for industrial use, you have to tell it at every step that you want information from a particular unit. I mean how many heat pumps does one house have?
- App not updates for years and I mean updates that add functionality or address issues not just keep it compatible with the App Store.
