Worcester-Bosch have announced a new controller called the Wave that can be programmed and adjusted via a smartphone. Few details are available yet, but there’s a bit more here than is given on WB’s own site. The launch date* for the Wave will be 15th September.
The good news is it works with WB’s proprietary boiler control system, Heatronic 3, and so can control the boiler parameters more accurately. Most other smart controllers simply replace the on/off thermostat control function. It promises weather compensation but using the internet weather reports rather than an external sensor.
It fails my criteria for a true smart controller, however, as it doesn’t talk to individual TRVs, you have to set those yourself. There is a project to reverse engineer the Heatronic 3 interface and so there’s hope that some of the open source projects can extend the functionality to make it truly smart.
*Update: Well, it has missed September and the latest I’ve heard is that it will be “out in the near future.”
