Thermomix Friend® must be placed on a clean, solid, and even surface so that it cannot slip. Do not place the base unit on the power cord. If you do, Thermomix Friend® will not sit evenly on the surface.
We are using a common Bluetooth® standard module in the Thermomix Friend®. Its reach can be compared to the reach of modern Bluetooth®. Thus, walls could interrupt the connectivity. However, we recommend to place Thermomix Friend® in the same room as TM6, since in a connected recipe, bowls need to be transferred from one device from the other, which complicates the process the further both devices are apart from each other.
