Somfy 1870879 4-Channel RTS Handheld Transmitter 433.42 MHz

Handheld radio transmitter with four channels for controlling Somfy RTS motors and receivers. It sends Up, Down, Stop, and My (favorite position) commands on the 433.42 MHz frequency, with a range of up to 200 meters in open field and 20 meters indoors through two concrete walls.

Advantages

One transmitter can manage up to four separate devices or groups, so you can control roller shutters, awnings, blinds, lighting, or gates from a single remote. The My button recalls a preset favorite position, and the wall mount keeps the transmitter within reach. Powered by a CR2430 lithium battery, it lasts about two years at six operations per day.
