I was advised years ago by one of my trusted "Elmers" who had lots of
experience with radio gear in the Navy that it is better to cut a window in
your radio room than take a risk of an unexpected or uncontrolled motion of a
tower. I was also advised when I was in the wind turbine business (very
briefly) that the most dangerous thing in the modern world is an electrical
engineer controlling a high power mechanical system!

Or, some form of low voltage relays and a hardwire connection.
Or a WiFi connected relay controlled by a dedicated app, but I'd be a bit
nervous about trusting a "safety sensitive" function to Alexa, without some
serious interlocks or a fairly robust physical access control. It's kind of
like those ideas about automatically lowering the tower when the wind goes
above a certain speed. It's more complex than one thinks at first.
I've built a fair number of network controlled devices, some controlling big
heavy things moving around (dish antennas, etc.) - It takes careful planning
and design to make sure it "fails safe". For this, since you've already got
to have power wires and coax going out there, adding a few wires to control
some relays seems a fairly simple and robust way.
