All Yeelight lights - no real response

[S474N]

Hi, I have about 11 lights (650, 350 and led strips) and have problem with control from Homekit or Homebridge UI X. I migrated all lights to IoT VLAN (different subnet).

All lights are set correctly in config.json (override name, but in UI X is visible only model, not assigned name), also have on my router enable mDNS and IGMP Snooping. Pings from my LAN (also from RPi with Homebridge) to lights in IoT VLAN are OK.

If I turn on light in HomeKit, there is automatically turned on in Accessories in HomeBridge UI X, but real light is still turned off.

Tested also deleting my Home in HomeKit and creating new one. Same problem.

Where can be problem, please? Have also "log":true in config.json with every light, but there's no info in log.

Homebridge v1.0.4
Node.js v12.16.3
npm v6.14.4
homebridge-yeelighter v1.2.42

Today tested commands via telnet IP 55443 from my main LAN and everything works perfectly to IoT VLAN, where are located lights.

Can you please add Location IP as new "override" (next value in "Optional per light configuration")? I think, that problem is here.

Next day of testing - cleaning cached devices, move one light from IoT VLAN to LAN.

Homebridge log:

And this light works perfectly in same LAN as RPi/HomeBridge server.

Can be option in plugin, for disabling discovery/broadcast and using fixed IP?

[cellcortex]

The multicast is used to discover the device and it's properties. In principle you could put all the information that the response contains into the config and it would work. However I am afraid it doesn't make sense to put a fix for your network configuration into this plugin for everybody.

You can either:

• fork this plugin and add the things you need (but I don't think they should be accepted as a PR)
• change your network config to allow for the SSDP query on port 1982 and the response to pass through.

Sorry

@cellcortex: hi, thank you for reply.

Fix for my IP configuration to plugin is nonsens, but I think support for define IP. Please see for example plugin Broadlink (section Device Discovery and hosts):
https://lprhodes.github.io/slate/

I think the same, that will be IP in override section, for example:

"platforms": [
  {
    "platform": "Yeelighter",
    "name": "Yeelighter",
    "override": [
      {
        "id": "0x00000000deadbeef",
        "IP": 10.0.0.1
      },
      {
        "id": "0x0000000012345678",
        "background": false,
        "nightLight": true,
        "IP": 10.0.0.2
      }
    ]
  }
]

The same problem as me have everybody with IoT VLAN.

Or can you write me, how can I define the config response manualy? Thank you again.

[cellcortex]

This would require quite some changes to the lifecycle of lights in the plugin. The configuration of the light is sent via this registration message that apparently your vlan filters. So all of this would have to be configured manually.

Isn't there a way for you to config your gateway to forward the SSDP / multicast?

[cellcortex]

will accept pull requests for this.

@cellcortex: I have USG-PRO, enabled "IGMP snooping" on both (LAN and IoT VLAN), also enabled Multicast DNS (mDNS) and nothing.

Here are threads on Unifi forum about SSDP:

But there's no real solution.

Is way to add lights manually? If you tell me how, will test it.

[S474N]

SOLVED! :)

I was set IGMP-Proxy, configured both interfaces LAN and IoT VLAN, added firewall rules (UDP, 239.255.255.250, port 1982) and it WORKS!

But have this problems:

• don't know why, there is delay about 18s between turning on light and showing it as ON in Homebridge UI-X. If i turned light off in this delay, there is no response from light. In HomeKit is everything OK.

• have two lights directly in HK, both disabled in LAN control and also override in config.json ("ignored": true). But 1 light is still visible in UI-X and also in HomeKit.

[S474N]

Delay is really big and annoying problem. Click on OFF, light goes offline, in log nothing and delay about 20s, then icon changed to off.

Here is my log:

Next try, click to ON. Light is ON instantly, but in UI-X and Homekit nothing. Delay about 20s, then icon changed to ON.

[cellcortex]

Homekit is updating the value on the client side automatically which is why I didn't query the values right after they are set - especially since yeelight has some limitations of how many messages it wants to handle per minute.
I can try to add code to update the home bridge accessory with value that was just set.
