Is it possible to make an older model garage door opener smart?
Absolutely! Most older model garage door openers have an option to add a wall control panel / push button which you can use to open or close the garage door. Smart garage door openers can be wired to these push button terminals. When the user wants to close or open the garage door through the smartphone app, the smartphone sends a signal to the smart garage door opener, which in turn acts like a push button and operates the garage door.
How do smart garage door openers work?
Smart garage door openers consist of a wireless module (Wi-Fi, Bluetooth, Zigbee or a combination of these protocols), a power management unit, one or more relays and some input terminals for accessories and sensors.
The way smart garage door openers for older models work is illustrated below:
The smartphone connects to the smart garage door opener unit via a wireless protocol (such as Wi-Fi, Bluetooth or Zigbee). When the button in the app is pressed, a signal is transmitted to the smart garage door opener, which pulls in a relay for a certain amount of time. This has the same effect as a push of a button from the perspective of the garage door opener, which will then open or close depending on its current status.
How can I make my older model garage door opener smart?
On most garage door opener control boards, you'll find a terminal for a push button or wall control panel. You can wire the control signal cable of the smart control unit to these terminals in most cases.
A lot of manufacturers use different naming conventions for these push button input terminals. The most common naming schemes are:
- CYC (an abbreviation of Cycle, as in cycle through the opening and closing phases when the button is pushed)
- OSC (stands for Open/Stop/Close)
- IMP (an abbreviation of impulse input)
- PB (stands for Push Button)
- SBS (stands for Step-by-Step)
- STRT (abbreviation of Start)
- SW (as in Switch)
- TRG (stands for Trigger, as in triggering an impulse to open or close the garage door)
