garage door opener app

Has anyone written a garage door opener app for android that doesn't require the purchase of a wifi or bluetooth device to be installed on  the garage door opener?

Thanks

Garage door openers operate on a rotating radio frequency model. Smartphones simply don't have the required circuitry to transmit such signals which means you would need some kind of intermediate device. I use a Z-Wave 120vAC relay attached to my garage door for just this purpose. It works flawlessly but I did need to purchase a SmartThings hub and the relay to get it to work.

Russ are you based in the Uk or US? Reason I ask is because Smartthings has just recently launched in the UK and I understand the Smart hub 2 has both the zwave and zigbee wireless protocols.  Do you use zwave devices or a combination of both protocols?

What is your view on the smartthings hub?  Do you pay a monthly subscription (if in the US)?  At present I use the zwave Fibaro but thinking of changing.

Thanks.

I'm in the US. I use both zwave and zigbee devices and it works very well. No monthly fees, just the cost of the equipment. It's a good system.

Could you please let me know what criticisms you have of the hub or of zigbee, just so that I know some of the downsides?

Thanks.

I've needed to add a zwave relay to my house to reach everywhere. The signal just isn't strong enough to cover the entire house. Not a big deal, it was easy to configure.

Sometimes binding a device can be tricky but I've only had that problem with 3rd party devices. Binding Smartthings devices to the hub is a snap and works like a charm every time.
