I am currently using my C-4 to control a number of room lights at various points around the house together with a couple of smart switches that use geofencing option. In general, all works well, other than the occasional geofencing issue.
You may be aware that Google is removing app support from Nest Thermstats Gen 1 in October in Europe. No doubt others will follow in the future. However, they are suggesting the Tado X as a replacement. Geofencing only works on the Tado X with a subscription, so I am wondering if anyone has any experience with using the Tado X with geofencing on the C-4? Alternatively, I was also looking at the Honeywell T6 R as an option.
For either of the thermostats, the 'learning' aspect is also important to me in that the Nest considers the outside temperature and the time taken to bring the area up to temperature when activating the heating.
My heating system is quite basic, water-filled radiators and a hot water cylinder.
Any advice or recommendations would be greatly appreciated.
Yes, there are integrations for wifi thermostats, but do you really want to use them with a local hub? I had some Honeywell wifi thermostats and I replaced them all for HoneyWell T6 Pro Zwave to have total local control.
I would not recommend any Honeywell wifi thermostats, when I had them the API calls were severely limited and I could only poll them like every ten minutes to avoid going over the limit, meaning that a change made would not immediately reflect on the hub until the next poll for the status was made through their APIs from the integration.
The T6 Pro Z-Wave would be a great option, except that I need it to connect wirelessly to a heat-link. The wired boiler connection is at one end of the house, and the thermostat and control is at the other end.
My understanding is that this is not possble with the T6 Pro Z-Wave. If this is possible, then, problem solved.
I guess it comes down to where you want the control, versus just sensing temperature.
You can buy a remote temperature sensor add-on for the room you have the thermostat in now, and move the thermostat and control back to where the boiler connections are. Then you can set it to modulate based on the room the temp sensor is in.
That is not the same type of remote control as what you have now, but it is an option.
Doesn't Z-Wave run on a different frequency in Europe? Would the T6 work on that frequency?
I'm interested in the subject but don't know too much.
I searched a little on Tado X and, depending on model, they seems to support Thread and also Matter, mentions Apple Home and the Google equivalent. So, I imagine you could connect with Hubitat, but I imagine you would need a device driver to run it? Would you actually need to buy a subscription if you used it with Apple Home or Google for geolocation, or is it just for their hub, border router, or whatever the term is?
Maybe just Apple Home or the Google thing would give you the functionality you need without the subscription fee. You wouldn't be using the Tado X app, I imagine, where they would charge you. Even if it wasn't interfacing with Hubitat because of a lack of driver at the moment (or maybe, the generic thermostat driver would indeed work), maybe that would be good enough.
I can control my Ecobee thermostats locally (without the cloud) with the Apple Home integration app. I looked at their site though, and Ecobee only supports in US and Canada.
I'm not sure anticipation is that rare anymore with modern digital thermostats. My Ecobees do it, but not sure if outside temp is taken into consideration, which would be via WiFi in my case.
Good luck.
edit: Also, C4 is pretty old at this point. Could be a problem.
Google said sux to be you. We are bricking your Nest Security system. Why I am moved to Abode. Then they told the same thing to their Nest thermostat customers. Honeywell T6. Works well.
What is a thermostat? A thermometer connected to a switch. With hubitat, you could use a z-wave temp sensor placed were ever you want. Then connect a z-wave dry contact relay to the heater control. Make a rule to control it. No wall control which is inconvenient. But in a pinch that would work.
Honeywell have told me that they don't have any Z-Wave thermostats available in Europe, so either way it looks like it'll be a WIFI one.
However, I think I'll probably just settle for the Tado replacement that Google are suggesting and making available at a discount of 50%.. I do see that Hubitat users have provided a driver, and succeeded in successfully integrating it into routines.
Hey there
I'm in the UK and we have 4 Nest thermostats connected to a wiring center which in turn controls the boiler. My plan was to use a z-wave relay (or 4) beside the wiring center. These can be controlled by HE hub. You don't need the heat link anymore. I'll replace the nests with z-wave thermostats.
Honeywell Home TH6320ZW2007
These sells on amazon in the UK. Is UK not the same frequency as Europe?
