6410330 Digital 1-channel timer clock, TR 641, year program, app

The TR 641 top3 BLE RC year timer clock offers further possibilities for all conceivable control options. It combines time AND astro functions, has 16 special programs and a central OFF function, can be programmed via the (deactivatable) Bluetooth BLE module (maximum protection against manipulation, since no cloud and no gateways or routers are necessary thanks to local Bluetooth connection) and even the WWF's Earth Hour is pre-programmed until 2044 and can be activated at the touch of a button. Operation, which can of course also be carried out directly on the device, remains simple and is carried out (graphically or in list form) on a smartphone or tablet. Three twilight ranges (sunset, twilight and darkness) are specified for an astro function, and sunrise and sunset times can also be fine-tuned using an offset. If you want to be absolutely precise, you can connect an external DCF or GNSS antenna, whereby GNSS also enables even more precise positioning in addition to time synchronisation. An astro impulse, e.g. to control shading, is also available.
