Astronomical digital timer with Wi-Fi RAT-1PT-WIFI

Wi-Fi/BLE astronomical timer for automatic control of electrical devices at sunrise and sunset. TUYA, 1 channel, 16 A/250 V AC, 24–240 V AC/DC, DIN 18 mm.

Technical info

RAT-1PT-WIFI is a digital astronomical timer designed for automatic switching on and off of lighting and other electrical loads according to sunrise and sunset times. The device automatically calculates astronomical time based on the configured geographical location and time zone, so the operating schedule adjusts to changes in sunrise and sunset times throughout the year.

The timer is configured and operated using an application in the TUYA environment. The device communicates via Wi-Fi IEEE 802.11 b/g/n and BLE 4.2 Low Energy. In the app, the user can set, among other things, the date and time, geographical location, offset relative to sunrise and sunset times, daylight saving time, and the operating language.

The timer also allows a night-time break to be programmed, which temporarily switches off connected loads during selected night-time hours. This function can be used, for example, to reduce energy consumption when lighting or other devices do not need to operate. A holiday mode is also available.

The RAT-1PT-WIFI is a single-channel device intended for automation and control systems. Its wide AC/DC supply voltage range allows it to be used in various installations.

The compact housing is only 18 mm wide, equivalent to one installation module. The device is designed for direct mounting on a 35 mm rail compliant with PN-EN 60715, so it takes up very little space in the distribution board.
