Principles

We’re on a mission to reduce the carbon emissions of the entire UK by 10%. We’ve got bicycles, beer, it’s dark (when it’s winter) and we occasionally wear sunglasses.

On our journey, we don’t want to forget the key design principles behind OpenTRV, so here they are:

  • Target a 50% reduction in UK domestic space heating carbon footprint in existing UK housing stock (with poor thermal efficiency and gas fired central heating with radiators)
  • Basic OpenTRV system should be cheap and simple to retrofit by end users (and in many cases repay its cost in a single heating season)
  • Support those most in need of help with their fuel bills including those in social housing
  • Operate without requiring an Internet connection or smartphones; be able to do basic operations with a simple UI physically at the radiator or its associated control unit
  • Systems should degrade gracefully, where necessary for it to occur
  • Produce permissively licensed free libre open reference designs suitable for large manufacturers to produce at low cost
  • Keep some or all of its designs suitable for computer, electronics and/or DIY enthusiasts to tinker with and extend
  • Minimise user costs by promoting WiFi levels of compatibility between manufacturers, allowing mix and match systems with components from different manufacturers to be assembled and upgraded
  • Interoperate with existing systems such as OpenEnergyMonitor and give users easy access to sensor data and other useful capabilities while keeping an eye on privacy and security
  • Interconnect with home automation systems

    I have picked up a reference to your website from the Edinburgh hacklab page. I’m interested but puzzled because your stuff is laced with obscure abbreviations. For instance what does TRV stand for? Please provide an explanation or a list of your more common abbreviations as one of your pages.
    Thanks
