Firmware
Firmware is software that is responsible for the basic functions of an electrical device. As a "normal" user of smart home devices, you don't need to deal with the firmware. It is firmly anchored to the device and requires no user intervention. Only "smart home hobbyists" who want to program their own smart home system from a variety of manufacturers and without the use of the cloud may have to replace the pre-installed firmware with another firmware. Tasmota firmware, which is available free of charge, is often used for this purpose.
At wesmartify you get actuators on which the Tasmota firmware is already pre-installed: Den wesmartify smart home actuator Shut It TASMOTA for smart control of roller shutters and the wesmartify smart home actuator Switch It TASMOTA for automatic control of light switches and sockets.
