Device paired but Service disappearing in Home.app from time to time#

You managed to pair with Accessory or Bridge but after a while, it has disappeared?

1. Make sure that the device you are using to view Home status is connected to the same network that node-red (with nrchkb) is running on
2. If you are using VLAN or special firewall rules, join us on Discord to discuss what settings should be for things to work

1. Make sure you are using the latest version of our node.
2. Look for other HomeKit nodes that you have installed. You will have to remove them if they collide with our node. Possible collisions with:

• node-red-contrib-homekit
