I want to modify a few devices so I can use them with OH.
For example a Senseo coffee machine or Irobot vacuum cleaner.
I’m looking for a small zigbee device to connect in parallel with the hardware button in the machine. The device (relay or switch?) must fit in the device and NOT work on batteries. It also needs to give a “pulse” instead of a “normal open/closed” contact.
I have no idea where to start. Any ideas which hardware I need?
