“A few points
1. A little disappointed with the very little information about differences between the C5 & C7. from HUBITAT.
2. Z-WAVE node attachment now prompts before adding a device to the network asking you for information on your node address before connection to your gateway. This is a problem if your Z-wave node manufacturer does not print the info on each device.
3. You don't need and external USB device with this one in the EU. The C7 has an internal antenna.
4. C7 is definitely faster.”
