A programmable RF hacking tool controlled by your smartphone. Gollum can replace almost any radiofrequency remote control. Gollum can control any garage door opener, roller shutter, etc… Gollum is connected to your smartphone using Bluetooth. Gollum allows you to save your RF devices & share control with whoever you want. Gollum allows you to be totally free from vendor specific remote controls. Gollum SW is evolutive. Gollum is open hardware and open API. Gollum: is a programmable RF remote control, is programmed with your Smart Phone, works in standalone mode (battery inside), can acquire & show you RF codes from your existing remote controls, can generate new codes for any existing brands and models, replaces various existing remote controls from different vendors, allows RF data to be transmitted & received, can communicate with any proprietary RF device.
