Ion Home

Overall it’s a good app with nice features. However, Since iOS 18 it seems to freeze when switching between apps like if I don’t close the ion app, switch to something else then go back it’s unresponsive. I have to close the app and reopen it. One more thing to note. A nice feature request would be to update it to show which system is running. On the thermostat it shows gas or heat pump heating. It would be nice to have that displayed on the app as well. Other than that it’s a good app.

The weather part of the app stopped working other that it does respond good and function well.

Your last update broke my connection to the internet making online access impossible. Where is your QC?

While I love my system, the company needs to scrap the thermostat/app requirement and let people use what they want. Being captive to software that’s well behind the competition and hardware that can’t remain connected to servers is extremely frustrating for a system that cost thousands of dollars. Love the system but desperately miss my Nest thermostat, its ease of use, ability to connect to Alexa without disabling the app requiring a system shutdown to correct, and its monthly statistics. I wish I would’ve selected the mid-level HVAC system instead of this higher rated system simply because I could’ve avoided this Ion interface.

Do Not Buy This Unit otherwise you will be spending more money on the electric bills because if you’re outside at work thinking you changed the temperature but on the other end it will no response Apps never works with thermostats to control, Schedule never works. They should name it HellMaker

Update today messed up the email field. When I enter my email correctly, it says it’s not a valid email format. I can log in online through a browser, so this is 100% an app issue.

Here it is end of 2024 and there’s still no HomeKit integration despite this being promised to be on the roadmap in comments from MFR here many moons ago 🤷🏼‍♂️. Still no smart sensor integration, unlike ecobee.

Would love to have a feature that allows the fan to run in a circulate mode. Some will run 20 minutes an hour. Thank you for your consideration.

This ION thermostat was difficult to set up and the installer tech was unfamiliar with how to set it up to get the app for the iPhone. I phoned ION tech support then and they helped somewhat, but after I got the app from the App Store, it still doesn’t let me control the thermostat settings like I used to with the Nest app. I will have to contact ION support again.

The ION installation and the app are closely coupled making local and remote access seamless and convenient.
