I'm looking to create a two-bell system for my doorbell. I have one button and currently one bell (Edwards-Signaling-340-4G5 Bell, 24VAC, 0.250A) already installed. I want the first bell to ring during certain hours and the second bell to ring at other times. The first bell is up and running, and I'm planning to add a second bell around 150-200 feet away. I have a few questions: Is there a cheap, ready-made solution for this? Can I use an ESP32 over that distance, and if so, what kind of signal booster would work? I'm also wondering if connecting it to public Wi-Fi would help with time synchronization. Any alternative suggestions? Thanks!

1. Yes, there are wireless doorbells out there that support multiple bells. They're usually pretty affordable.
2. You can definitely run an ESP32 over that distance! A signal booster would help; I recommend using a transistor or a hex inverter for signal conditioning.
3. The ESP32 will work, but an ESP8266 might be more cost-effective for your needs. The mini D1 Pro has an external antenna option that can help boost the range. If you've got some basic C++ and networking skills, you can set it up to handle doorbell events over Wi-Fi—even from anywhere else in the world as long as there’s an internet connection!

Thanks for the informative reply!
