We reported the higher CPU loads many months ago, while testing the first V14 builds. It was after they added the Play-Fi part, that CPU loads went up, and by that, also temp. of-course. We calculated that the services needed to get Play-Fi on the device brings about 25% extra load. You can remove and disable Play-Fi system apps, but one part cant be removed or blocked and that still uses about 10% on all 4 cores all the time. Another service, partly related to Play-Fi is using 15% on all 4 cores.
To provide evidence that Play-Fi is the main issue, we tested with a Homatics R 4K V14 build on the R Plus and the issue with high CPU loads are gone, and temp. dramatically went down. We also used the V14 build for the R Plus prior to the one in which Play-Fi was added, and that also showed the same behavior, CPU load way down, and temp with it.
So Sei Robotics (Homatics), must do some build cleaning, but I ask myself if they will drop Play-Fi from the build when they can't get that part sorted out. We think users are not really using Play-Fi at all.
