Just me thinking as I type (while trying to do both) that there are a couple of approaches to remote monitoring. One is examination of the radiated signal. This can be as simple as listening to it on a receiver and could extend to measuring the FS (done here) and perhaps the frequency.
The other is to monitor the current into the transmitter (also done here)since the source is indoors and is easy to instrument. This monitoring, though gross, does indicate when something has changed and is sensitive enough to indicate rain detuning the antenna.
I had previously thought, and so did 12Vman if I recall correctly, that it would be nice to be able to constantly monitor the antenna tuning with the ability to remotely change it as needed but nine months’ experience with the outdoor system shows that, except for transitory weather effects, there is no change in tuning so monitoring and/or adjustment is not worth the effort. Given that, it still would be neat to have the capability.
