I often read the forum and, having a technical background, I find many of the posts interesting and informative. However I have no need or desire to implement most of the ideas because they do not fit with my requirements.
I have a well insulated A rated home with an A rated boiler, solar PV, solar thermal HW and a diverter to use excess solar to heat the HW. I also have 2 air con/air source heat pump units. We are at home most days and have no set schedule for when any room will be in use and times and durations of periods away from home are quite random. To get the maximum benefit from this I often need to operate things manually. I have not found any advantage from optimisation and would not anticipate any benefit from the Hot and Cold weather settings and the HW priority will be seriously detrimental for my system. My well placed and accurate external temperature sensor often shows significant variation from the temperatures indicated by EvoHome. Hence I have not asked to be part of the Beta test programme.
What I do find essential is having individual control of each zone. Before EvoHome I used TRVs and a room thermostat but could not get enough control of each room. EvoHome solved this fundermental problem.
The improvements that would benefit me are.
1. Change eco mode to offset mode and allow offsets of say +/- 5 degrees.
2. Allow individual zones to be switched Off individually (ie set to 5 degrees)
2. Please, please DO NOT make HW priority mandatory.
3. Improve battery management for the controller.
And on the hardware
4. Improve the reliability of the battery contacts for all components so that they do not need to be “bent” to achieve reliable contact. None of my other battery operated devices require this.
