KRYSTAL control unit for smartphone and radio control - tutorial

With the KRYSTAL control unit it is possible to control a roller shutter motor also with a Stafer radio control after installing the SUNNY module for smartphones. The two control units (Krystal + Sunny) will work perfectly synchronized with each other. The motor, which must be "mechanical", can be controlled via radio control, from your smartphone (even remotely), from the wall button and from voice assistants. Everything perfectly synchronized!
