Missed Opportunity

I am using the App to manage a Lyric T5 thermostat running a ducted air conditioner (HVAC) so this review relates only to that capability in the app. I live in Australia, and purchased the T5 unit from a US supplier. I thought I was in trouble when the app setup asked for a US postcode. I gave it one to get started. This caused the time to set incorrectly on the thermostat but happily a bit later on I was able to change the Timezone and all works well. The T5 thermostat HVAC parameter setup through the app was simple to follow and quick to complete.
The app makes it easy to adjust your heating/cooling schedule which is a distinct improvement on earlier not so smart Honeywell thermostats. It is also easy, using the app, to adjust the thermostat settings including temperature at any time, locally or remotely. I have not tried the geofencing option which allows automatic switching between temperature settings as your leave or enter a set distance from your house.
What’s missing? The app knows when the HVAC system is heating or cooling, however, there has been no attempt in the app (or I have not found it) to estimate or graph energy usage. This would be a very helpful option so users could see what the cost benefit of lowering the heating temperature or raising the cooling temperature would be.
The bottom line is that the app is simple to use, works well both locally and remotely but does not capitalise on its potential to monitor energy usage. Perhaps the app writers could add this feature to future updates?

Honeywell wifi disappointed

I hate having to enter a pin every time, then wait for it to think about giving me access.
It is so much more convenient to use a phone or iPad to adjust the temperature of the thermostat.
The thermostat seems to go off line quite regularly, meaning I need to adjust temperatures at the thermostat, and also to repair the device.
The automatic temperature and time setting, works well for me, but because of geofencing, the rest of y family can’t be warm if I’m not home.
I would like to turn geofencing off and use the automatic programming all the time, but this is not an option.

Missing postcodes for Australia for home location setup

App ok except it doesn’t recognise postcodes in Australia unless they are 4000 series (Queensland), 5000 series (South Australia or 6000 (Western Australia). If you try and use any NSW (2000 series) - for example 2001 for Sydney CBD - or any Victoria (3000 series) as your home address to setup the App it won’t proceed with the setup. Honeywell please fix this problem.
