I use a Rachio smart hose timer for my garden. I bought it mainly because I was too lazy to get up early to turn on/off the soaking hose. But I also use it because we travel a lot, and I can control it anywhere in the world through its app on my cell phone. The app tells me how much rain it thinks my house got and I can adjust the watering schedule accordingly. I think it would work for your citrus trees. However, I'm comfortable using it for a few weeks unattended but leaving a pressurized system for several months would be another story. Even when we are away, I ask my neighbor to occasionally look in our backyard to make sure we don't have a geyser going. If you have your TV house routinely monitored by somebody and/or cameras this might work.
