| - | === Pairing === | + | === Coordinator Hardware selection === |
| + | |||
| + | At first i bought a cheap chinese coordinator, | ||
| + | |||
| + | So far, the ZBT-1 has proven to be the **best** coordinator i have tried. YMMV. | ||
| + | |||
| + | === Naming Convention === | ||
| + | |||
| + | I name my ZigBee devices in Home Assistant with the following scheme: " | ||
| + | * TYPE: two letters code to identify the type of device (like LT for lights, SW for switches, TM for temperature sensors, and so on) | ||
| + | * FLOOR: 0, garden. 1 ground floor. 2 first floor, 3 roof... | ||
| + | * ROOM: 1 to X, where 1 is the leftmost room and N the rightmost room of the floor | ||
| + | * number: when more than one type of device is in the room, identify each one. | ||
| + | * name: human readable name like "main light of bedroom" | ||
| + | |||
| + | With this approach, it's easy to remeber where the devices are located for future maintenance. I also write with a good marker on the device itself, or on a label attached to it, so that when more than one device is closeby located, like mulitple smart-plugs or swiched, it's easy to identify them. | ||

| Each ZigBee device usually has a way to start pairing, you should refer to each device manual. In my experience the folling solutions will work: | Each ZigBee device usually has a way to start pairing, you should refer to each device manual. In my experience the folling solutions will work: | ||

| Start pairing one a time and not more than one device simoutaneously or things can get messy. Also, pair your dedicated repeaters first, AC powered devices second, and end-devices last. | Start pairing one a time and not more than one device simoutaneously or things can get messy.

| + | Occasionally you might have to reset the odd cheapo device, specially after a blackout, in order to get it working again. | ||

| ZHA provides a nice graph view to visualize your ZigBee Mesh network. From this view, you can appreciate how your ZRs are partecipating in the mesh and you can use it to understand where and how to add ZRs or move devices around for a more logical mesh distribution. | ZHA provides a nice graph view to visualize your ZigBee Mesh network.
