Need Apple HomeKit

My new HVAC unit required this thermostat in order for some of the advanced features to work. I replaced an Ecobee thermostat that I had integrated with my Apple HomeKit smart home set up. The old thermostat worked great but this one does not integrate with HomeKit, so it is like a major step back. I can’t understand why Lenix won’t do something so simple as to integrate with such a commonly used smart home system.

please keep the updates coming

I don’t mind how simple the mobile app is but i’d love to have the latest features other products have and be able to use homeassistant and apis to manage MY equipment.

Needs some fixes

Overall the app is mostly functional. The big issue for me is that the smart away function often doesn’t trigger based on geofencing. I went in a trip yesterday over 100 miles away for half the day and the thermostat never recognized that I was away.

As another reviewer mentioned, the proximity option does not work as desired. With the proximity option toggled on, I will need to really wave my hand in front of the device in order for it to recognize and wake up. But then, I’ve noticed that over time the screensaver will never appear like it is always awake.

The sleep options under current temperature does not seem to reflect in the app when the sleep hours are active. I have sleep time starting at 11pm, when 11pm comes there is no sleep icon next to the sensor I have designated as my sleep time sensor. Hours later it seems to finally appear in the app but not at the correct time.

There are some nice to have items as well, such as being able to see which stage cool/heat is running, having humidity displayed along with temperature in the my Home Screen so I don’t need to click on each sensor to view the humidity.

Being able to configure alerts for humidity would be helpful as well, such as a phone notification when a sensor measures over a customized humidity level.

Still not updated from S30

Although this is supposed to be the App for the new S40, there is still verbiage from the older S30 app which Lennox has not updated. Also, the Smart Away (geofencing) feature works only occasionally on the iPhone. After 3 complaints, Lennox Customer Support said a future update (timeline unknown) would fix it. I am not sure whether that was a way to stop my constant calls or whether they were really on it. If the latter, I don’t see any official statement anywhere. (In the meantime they are selling a product promising features we paid for that don’t really have exist. Lawsuit anyone?). But I gave 3 stars as the HVAC system itself seems solid, and the rest of the App is more or less okay (once you get around unclear wording of some choice options).

Works fine for the most part

Not sure about the other review I see here from Canada where the person had registration issues, as I was able to do so quite easily a week prior...

Anyways, the app works fine for the most part, though there are times in certain sections/areas where after making a change a box appears indicating it’s processing but nothing ever happens and you must force-close the app and restart it.
The only other complaint or feature request I’d ask for would be to allow the full configuration options in the app “as they are” on the thermostat itself (including the advanced settings which currently require having physical access to the thermostat plus using another app in order to make adjustments - which (by the way) make using said app almost pointless, as you need that physical access anyways so you might as well just make those changes at the thermostat).
When trying to get a new system working exactly as you wish (considering all the configuration options available), plus the simple fact that it will take a week or two to fine tune those settings, it’s quite inconvenient having to constantly be running to the thermostat itself to make those minor tweaks several times a day and over a several week period...

Poor so interface

Too complex. Too many clicks to get to frequently used features. Overly complex. Sometimes does not turn HVAC on even though temp is far out of range.
Have to set temps 4 degrees higher because thermostat is poorly calibrated.

Real postal code in Canada deemed invalid

When creating a new home, I chose Canada and entered my BC postal code , but wasn’t able to proceed to the next step because the app kept yelling “please enter a valid zip code”. I had no choice but to use a US zip code to walk around this bug, which is just ridiculous.

You need a web app

Let me know when one will be available. Much needed. The iOS app is great. Simple yet powerful.

Lame

Hard to connect. Software writers dream but users burden.

Does not work with Alexa

There is currently a problem connecting to Alexa so if you try to use this app with an Alexa device, it will not work. This problem is known by Lennox and they apparently are working on it but it has been quite a while.
