It's been almost a year since I introduced you to the unofficial Friends of Hue switch from Sunricher. The Asians have created a module that looks confusingly similar to the familiar and official EnOcean module. And they still stand by their statement that Philips Hue cannot exclude these not-quite-official switches, which are powered by a coin cell, from the Hue Bridge.
I have already reported several times about the Sunricher module, which is equipped with a battery and can be used in the Hue app just like a normal Friends of Hue switch. Since no kinetic energy has to be generated, the switch is much quieter when pressed. However, the frame and rocker, which Sunricher supplies as standard, are not really of good quality.
