I want to build a garage for my robotmower and I want a port that opens when the robot leave the charging station, close again during the time the robot mows and then opens again when it´s time for the robot to return to the charger. I have a Mammotion Luba 2 Mini, that doesn’t have any app in Homey. It does have a intergration in Home Assistant but I have never used HA and have zero knowleage when it comes to how to use HA. Opening the port could be done easy with a switch that sends a signal when the robot leaves the charger. But I don’t know what to use to be able to open it again when the robot returns. Another issue would be that the port needs to be able to open very fast, both when the robot leaves and returns, a linear actuator would probably be too slow. Maybe a electro magnet would work? But then I don’t know how to close the port again. There must be someone that have made something similar? ---

Use a servo motor used in rv hobby. Will open very fast. Why not leave the port open when the lawn mower is active? ---

A servermotor might be the solution. The reason why I don’t want it open is simple, that’s the easy way of doing it and how most people do it. I don’t like the look of an open port but if I can’t figure out a solution that’s might be what I end up with. ---

Maybe a proximity sensor. I do not have any experience with this ---

Any ideas? ---

You may have solven it already, but if not. There are shutter/garage door controllers from several brands like Qubino and Shelly. Paired with a standard industrial proximity sensors or simple limit switches you should be able to control the port. Proximity sensors will also work to trigger the opening both in and out instead of the normal push button. I would put a simple wiper motor on the port. Cheap and easy to control. The old school way of doing this is by limit switches and a couple of relays connected so they latch. There are plenty of instructions on-line, even AI managed to get it right when I asked 😁 Hope this gave you some ideas.💡 ---

Do you have any sensors in mind? I guess that you are from Sweden, so if you know any store or e-store that have one that would be great. ---

Hej! Beror lite på. Proffsgrejer Automation24.se, men då är det oftast lite dyrare och 24V. Använder den typen till min riktiga garageport (och industrimaskiner jag höll på med förr i tiden). Farnell och Elfa Distrelec har också. Billigare grejer [electrikit.com](http://electrikit.com) och m.nu. 5V som är enkelt att mata och kan driva både 5V relä och andra digitala ingångar. Jag har inte provat just denna själv, men vill du labba lite verkar den trevlig, electrokit art 41024083.
