SMLIGHT SLZB-06 Zigbee coordinator

The slzb-06 is great. I use multiple. Instead of thinking about physical space partitioning, separate devices by brand. Different zigbee stacks on bulbs, plugs, etc can lead to bugs. I have a hue network, an aqara network, and a misc network.

You need a zigbee controller that talks to HA. I just switched to the SLZB-06 and really like it. You can power it via POE if you have that available so you can place it somewhere centrally located to your devices (doesn't have to be plugged into your HA server), or can just power it with USB and it has wifi to connect to your network

I've just moved my network from sonoff dongle p to slzb 06, and my lqi jumped from 80 to 180, it also can be managed through http after connecting Poe cable

Zigbee is rock solid. I recommend a SLZB-06 POE coordinator.

Get a SMLIGHT SLZB-06 as your Zigbee coordinator and any zigbee temp/hygro sensor. I am running Shelly H&G Gen3 and Sonoff snzb02p

As for the coordinator, I've used the Dirigera hub from Ikea since before entering the Home Assistant world, and it's surprisingly good. But still limited, in particular for switches. Most people who have tried several options swear by the SMLight SMZB-06. Mine is in the mail, I'm eagerly awaiting it. Zigbee2MQTT (Z2M) seems like the most robust way to go for future-proofing, so that's the HA route I'll take. The other one is ZHA, built-in, less flexible, less support for uncommon devices. As for expanding your meshed network, powered devices act as routers/repeaters, battery-powered devices …

Moving to mini PC and consolidating all zigbee networks to one Z2M via SLZB-06 will go a long way.

This is more for a purchase to optimize my zigbee network. Buying the SMLIGHT SLZB-06 and putting in the middle of my house completely sped up my zigbee network.

I personally have been running a zigbee router (SLZB-06) with IKEA Zigbee aplliances (lights, smart plugs, etc) and couldn't be happier. Cheap, excellent IKEA customer support, local and reliable.

How big is too big for Zigbee?. I’m now running 94 Zigbee devices in my smart home, all connected on the same network through a single hard‑wired SMLIGHT SLZB‑06 coordinator. It’s a mix of end devices and routers, with far more routers than end devices. The brands are mostly Ikea, Philips Hue, Aqara, Sonoff, and INNR, with a few others mixed in. Most are smart bulbs and switches, though there are quite a few energy monitors as well, which I know can be very chatty. My Home Assistant instance runs as a VM with 4 cores and 8 GB of RAM on my Unraid server, while Zigbee2MQTT and Mosquito run as …

The SLZB-06 is honestly a solid choice for getting started - it handles both zigbee and matter over thread which gives you good flexibility down the road. I'd probably skip the official HA hardware for now since you're just starting out and focus on getting one good coordinator that can handle your existing aqara stuff For zigbee specifically that slzb-06 will work great with your current setup and you can always add zwave later if you find devices you really want that need it

Another vote for SLZB-06 or SLZB-06M. Reportedly the 06 is best suited for Zigbee2MQTT and 06M for ZHA. However, I’ve been using the 06 with ZHA for a year now without any problems. I like it so much, and now since my home automation is reliant on zigbee, I’ve purchased a 06M as a cold spare. Their website has links to the official Aliexpress listing so you can pick them up at a good price if you’re willing to wait a week or so for delivery. https://smlight.tech/sg/slzb06

Slzb06 central in the house Z2M Remove all vendor hubs At least one zigbee router in each room From there, everything has been rock solid. Even battery powered cheap Aqara motion sensors haven’t missed a beat in a couple of years. I’ve got houses nearby but can’t see anyone else’s WiFi network. Maybe congested wifi gives some people issues. My zigbee lives alongside household wifi mesh. Can understand issues with physically sparse zigbee networks when people first start but once you get at least one device per room, I’d expect it to be really stable.

SLZB-06 is rock solid, handles 50+ devices without breaking a sweat and POE means you can stick it wherever the signal works best

The problem On a first-generation SLZB-06 device (ESP32 classic), the `smlight` integration raises an `unsupported_firmware` repair issue suggesting the user flash newer firmware via https://smlight.tech/flasher/#SLZB-06. However, no migration path actually exists for this hardware generation, all current firmware in SMLIGHT-Tech/slzb-esphome is built for ESP32-S3 (the newer hardware generation, "06xU R1-73"). Attempting to flash the available `.factory.bin` on the ESP32-classic hardware would brick the device (incompatible bootloader, partition table, and SDK). The user is presented with an …

My Zigbee adventure - i gave up. I spent between 20-24 hours over a long weekend trying to setup a smlight slzb06 zigbee coordinator with shelly products. The first 18 hours was spent trying to get the devices to be used in HA. They would show up in Z2M, but could not be seen or used anywhere else in HA. So I gave up.... I then took the suggestion of a fellow redditor to use ZHA. I played with that for about 3 hours. ZHA would allow me to see my devices and use them in HA. Only problem is, there was a time gap between every single step in automations. Example: turn a switch on ....5 seconds …
