Novice here. Send a "gate open" signal from indoors? A gate closes access to the driveway leading to my little guest house. Answered

I’m completely new to making electronically operated devices. I can't interpret and translate the existing rf signaling instructables to my situation. I’m also completely new to your impressive Instructables.com. Happy to be here. The situation: On a shared property stands a main house and a little guest house. Both are served by a single driveway. Access to the driveway is restricted by a gate. The main residence (not mine) utilizes 1. a remote control and 2. a drive-up keypad to send the "gate open" signal. (Aside: the drive-up keypad is paired with an intercom. The intercom serves the main house only. My guests, or delivery drivers, must telephone me to alert me of their presence at the gate. To open the gate for them, I must exit my little guest house residence, walk the length of the property, aim my remote control, line-of-sight, at the gate and depress the button on the remote control. The gate opens. I make the return walk to the entrance of my residence. This poses two problems: 1. guests and delivery drivers must wait while I make the journey out of the house, to the end of the property and 2. I must make this journey through inclement weather and nighttime darkness. My first goal is to achieve an indoor located, or a just-outside-the-front-door located, "gate open" signal sending trigger. I've read that wired signal sending performs more reliably than wireless, due to the abundance of potentially interfering wireless device traffic. I dunno. My second goal is to give my guests and delivery drivers a two-way voice communication "intercom" specifically with persons in the guest house. This communication device must be unobtrusive in appearance to be appropriate-enough to stick onto the drive-up keypad & intercom to the main house. A device operating as communication to the guest house belongs alongside the intercom button to the main house. That's so my delivery drivers don't buzz the main house, unnecessarily bothering the owners. That has happened. Makes me cringe. There must be many methods by which to solve the two challenges: 1. a guest house located, “gate open” signal sender. The signal reliably reaching the end of the property and aiming at the gate, and 2. a guest house located, two-way voice communication something. I’ve seldom even peered into interiors of electronic devices, and am confessing my entire ignorance of electronic signaling. Since I embody the least informed and least experienced person possible to achieve these to goals, it seems to me the simplest to assemble and test is the best, and that I begin with challenge one. I appreciate you for your time in considering how best to recommend I proceed. I'm in the dark. If you are very swift of mind and short of time, perhaps take a pass on this one. I need a most elementary, every little step described, no steps missing or out of order, type of response. I’m a neurodivergent individual. I’m good with it. And I will convey, from within my areas of creative visual fluidity, instructables in gratitude for yours, and for fun. And when other Instructables.com participants request guidance that I can offer, I’ll do so.

Hi, You left out some important info that needs to be considered for a proper answer. Approximately how far away is the gate from your guest house? If it's only maybe 200 feet or less you could run / bury a CAT5 Cable from the gate to the guest house. CAT 5 has 8 wires inside it. These 8 wires can be used to connect a second intercom and a SPST MOM (single pole single throw momentary contact) switch to activate the gate motor. Extra wires can be wired together to increase the Current limit of individual wires and lower the circuit resistance. How many wires will be needed depends on the intercom and gate control system. I would start by getting all of the Gate Motor and Gate Intercom Info (especially the schematic) and also research with the supplier if a piggyback system is available for your situation. I hope this helps. If not shoot me a message.
Have a great day
