“Pros:
* The thermostat was very quick and easy to install.
* Compatibility with the Aeotec smart hub and the SmartThings app makes setting triggers, complex schedules, and remote controlling pretty easy.
* It looks great!
* The display brightness adjusts according to ambient lighting, so you can see it clearly during the day, and at night you can see it while not getting blinded by an overly bright display.
Cons:
* Currently the SmartThings app only allows incrementing and decrementing by whole Celsius degrees, rather than 0.5 C steps like on the thermostat itself. I've submitted a request to SmartThings to fix that, so hopefully 0.5 increments will work in the app too.
* The floor temperature takes up screen space even if the floor temperature sensor isn't being used. Not really a big problem, but it would look a bit cleaner to not have that displayed if there's no value to show.”
“I have two HE-HT01 thermostats in bathrooms in my home. Firmware version showing as 0202 in parameter 03. I am having the following problems with both of them:
1) Floor temperature varies significantly. The temperature sensors in both bathrooms are varying by over 1 degree every time the sensor reports (every 10 seconds). e.g. the value will swing from 24.2 to 22.5 to 24.1 to 23.7... This results in significant load on the z-wave network ("spamming"). To fix this, I've changed the reporting threshold to 2 degrees variance (default is 0.2 degrees). Also, if using the floor temperature to manage the underfloor heating, the heating is constantly turning off and on (tick-tick-tick) as the temperature exceeds the setpoint at one moment, then reduces below the setpoint 10 seconds later. I am now using room temperature rather than floor temperature, with just a maximum floor temperature set to avoid the floor becoming uncomfortably hot for bare feet. Probably a firmware fix would work - aggregate the value over several readings.
2) Despite parameter 19 being set to 01, the clocks do not update automatically from the zwave gateway. (I am using a Homeseer hub). One is currently running 4 minutes slow. Note - they did update when first included in the zwave network, but have not updated since.
3) The set times cannot be varied from day to day/weekday to weekend. So, when you pick a morning time and that is applied 7 days a week. Only the temperatures at those times can be varied. So, if I get up later at the weekends, the bathrooms are still heating on a weekday schedule. e.g. the heating comes on at 6:30am, despite nobody getting up before 8:00am at the weekends. By the time people are having showers, the heating has switched off. I have been able to work around this using my home automation to extend the time at the weekends. Not great if you don't have a zwave network, and it really shouldn't be necessary.
4) There is an indicator which shows whether it is morning, daytime, evening, night. Whilst the heating is switching on/off at the correct times (in schedule mode), this indicator often shows the incorrect period. e.g. it will show day when the system has already switched over to evening.
Things I like:
1) Very configurable. You can adjust almost every setting through the zwave network.
2) The looks. A little cluttered for some, but I'm data-holic, so like to see the various bits of information.
3) You can limit the floor temperature and the room temp. So, if the floor is getting too warm, it will keep it at a set temperate until the room achieves the desired level. My old one used to just keep heating the floor until the room was up to temperature. The floor could become uncomfortably hot at times.
I do like the looks and the configurability, but a firmware update is desperately needed to fix some of these gripes that ruin a good and comparatively expensive product. It feels like there has been a lack of testing and consideration of how the thermostat will be used.”
“What they sent was white with a white trim not a silver trim which is in the picture. It doesn’t bother me horribly and didn’t need a different one but they might want to Qc their website”
