ELV MAX! Window Sensor Magnet Holding Clamp Dual Window Hack

cults3d

These objects can be used to make the ELV MAX! window sensors more useful and optically pleasing. They clip around the window frame, holding tiny neodymium magnets to trigger the sensor, instead of the original bulky steel magnet. The clips will probably work with the popular Homematic sensors, too. Please, leave a comment it you successfully tried that out! All you need are some Neodymium magnets 5x5x2mm to replace the bulky steel ones that are part of the sensor's retail package. I have got two window frame sizes, 14mm and 16mm thick. If you need something different, go copy and tinker with it! :-) The clamp has a structured mould on the window-facing side which is meant for applying glue. If the clamp fits correctly, it should also stay in place without any glue, though. And here is the hack-ish part: as the picture indicates if you find the right position for your magnets, the sensor will work correctly not only for one but for TWO adjacent window panes - even though this is not officially documented. To achieve that, you need to position the magnets very close to the center of the sensor, less than 2mm away from the case. The left and right magnet need to be in the same magnetical field orientation (just put them on top of each other and then separate them and put them into their clips without turning them!). You may need to invest some time in trying, pushing up and down and exchanging left and right bracket but once you get it right, one single sensor will correctly report if any of both window panes are open. That way you save one sensor installation for each double paned window.
