I have a Sylvania RGBW zigbee bulb, connected to my hubitat hub, It is located less than 20 feet from the hub, so I'm presuming it is connected directly (though I'm not sure how to verify that?). I seem to have an issue where the hub is sometimes not sending commands to the light.
I have both debug and description Text logging enabled on the bulb, but clicking on "on" or "off" in the interface is generating no log entries. Clicking on "Configure" generates log entries, and several of the "info" level entries indicate the bulb is on (it is not) and that the hue, and dim level are set. Other bulbs of the same type in the same room are working consistently. The bulb itself is relatively new (less than a month old). After an indeterminate amount of time, it will start behaving again.
This issue seems to happen every couple days or so, and tends to last a few hours. The hub is fully up to date. I've tried rebooting the hub. I've tried removing the bulb from the hub configuration and re-adding it. I've tried changing the zigbee channel on the hub. Any other suggestions?
They're pretty numerous ... I have a decent sized house and the majority of the lights are Zigbee. There's also a few peanuts. It would take a bit of time to enumerate them all. Are you looking for a count? Or just a sense of the make/model of the devices?
Both. Your symptoms suggest that this bulb is falling off your zigbee network. Do the symptoms persist if you move the bulb to be very close to the hub, saying within 4-5 ft?
You could also try resetting your zigbee mesh by powering the hub down for 15-20 minutes and then starting it up again.
A little tough to determine as the light is installed in a lamp that is ceiling mounted directly over my desk. The other lights in this room are wall mounted. A quick inventory (at least close to correct) looks like:
Samsung Smart Things Water Leak Sensor: 3
Samsung Zigbee Button: 6
Securifi Peanut Smart Plug: 12 paired, only 2 active (most are for Xmas lights and are not currently plugged in)
Sengled Element Classic (Dimmer only) bulbs: 12
Sylvania Osram Lightify Flood (RGBW): 14
Sylvania Smart LED light stripe 73661: 2
Sylvania Smart Zigbee (RGBW) bulbs: 27
Those plugs are zigbee routers/repeaters. The coordinator (hub) and device (bulb) currently have routes setup to use one or more of those plugs. Neither of them "knows" that the plugs are no longer available.
Would it matter that none of them were in the room were both the hub and the (intermittently working/not working) light are? Also, if the problem was that the mesh route was broken, wouldn't the bulb just "not work" rather than not work intermittently?
Those questions posed, I'm certainly willing to try both removing the peanuts from the device listing (which is a pain because next year I'll have to re-set up all the scenes, adjust dashboards, groups, rules, integrations with Alexa/Google, etc, etc ).
Is it worth it for me to try the hub powerdown test first?
