<div dir="ltr">We (COHEAT) have been playing with EvoHome for a while in kid brother's house. He owes us a writeup of the trials and tribulations involved in setting it up to do sensible things. Dusan?<div><br></div><div><br></div><div>-The radiator actuator hardware is well made. The best made out there, and probably the quietest out there too.</div><div><br></div><div>-The control sophistication of boiler and room temperature is basic, reliable and predictable* once you turn off any Honeywell attempt at intelligence.</div><div><br></div><div>-The control hardware/hub feels like something you'd order from Shenzhen for $39, not something you buy for £149, and is certainly not something you'd stick on a wall in a house. The battery life of the portable unit is a joke and the power consumption is excessive. </div><div><br></div><div>-The user interfaces - all of them - are atrocious. The time delays between interaction and action are excessive too. It's fair to say that Honeywell still can't do user interfaces, unless they happen to be a single knob on the wall. </div><div><br></div><div>-Their internet connection is as flaky as they come. Forget doing anything that relies on timely/reliable internet connectivity. The web portal is also worthless: you can't set the system up online (instead you must endure tedious menus on the local controller, and there's no way to export the settings or back them up, and they're lost when the battery runs flat in a power cut, and and and...) and you can't export data from it.</div><div><br></div><div>-You also can't do anything fun with the system, like control radiator valve positions or read room temperature directly, because Honeywell think they're the Gods of everything and save you from yourself by preventing access to such features.</div><div><br></div><div><br></div><div>*You need to turn off window detection and self-learning. Opening doors and wafts of air confuse the living daylights out of it. Fine if all zones are set to 21C, but the moment you try implement any real temperature differential between rooms you set off the window detection and introducing solar gain to the equation mucks about with the self-learning.</div><div><br></div><div><br></div><div>Good eRVs if they eliminate all screens/buttons from them and gave you access to the RF API. The rest is a complete hackjob.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 19 May 2015 at 22:10, Alasdair Macdonald <span dir="ltr"><<a href="mailto:alasdairgmacdonald@gmail.com" target="_blank">alasdairgmacdonald@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I don't know if google selected this for me based on my history, or if<br>
