out of memory error

[gtalusan]

I have a Samsung QN55Q90TAF. I use this plugin to expose the ON/OFF status to HomeKit, so my configuration is minimal. Just the IP address and MAC address of the TV are set.

This plugin is set to run on its own child bridge. Every few days, I'll see this message in the log file:

Don't run it as child bridge since the plugin already create a bridge for every TV.

Also you may have a problem if you used many inputs. But since you didn't post your config I cannot help you with this one. https://tavicu.github.io/homebridge-samsung-tizen/troubleshooting/open-new-issue.html

Here's the config. Does it help?

{
    "devices": [
        {
            "name": "Main TV",
            "ip": "10.0.1.71",
            "mac": "F4:FE:FB:54:36:B6",
            "inputs": []
        }
    ],
    "_bridge": {
        "username": "0E:E2:E0:9E:6C:1B",
        "port": 45071
    },
    "platform": "SamsungTizen"
}

Cool. So it's not from inputs. If you use many applications the plugin make a request for each input. That's why I asked.

ust remove the child bridge for the plugin. You don't need that.

Ok here's the config now.

{
    "devices": [
        {
            "name": "Main TV",
            "ip": "10.0.1.71",
            "mac": "F4:FE:FB:54:36:B6",
            "inputs": []
        }
    ],
    "platform": "SamsungTizen"
}

The reason I placed this into the child bridge is because I believe this crash has brought down my homebridge and smart home integrations previously.

What are next steps here?
