I have a Conbee2, with almost 100 zigbee devices. I am using the Conbee2 via ZHA. Routers are enough there. For years I have no problems. I have not changed anything.
Since about 2 months I have permanently problems:
The Hue bulbs are blinking: about 1min light and then about 3 flashes. Four hours, without an end.
the bulbs get offline and can not controlled via HA.
the Ikea and Tint bulbs are not blinking/flashing but still are disconnected, too.
I can power off and on, all lights off and on. Problem is not solved.
i dont understand why, but after hours of switch on and off, restarting HA… Suddenly it works everything again.
these crashes are coming faster and faster. Now every week.
not all bulbs at the same time are broken. Often the same, but tithout a pattern. It happens that 1 of 7 bulbs next each others has the flashing problem. The others are working well.
I tried:
restart HA, power off and on HA
power on/ off the bulbs, all repeaters
replaced 8 bulbs (new bulbs are using wlan instead of zigbee).
tried to read the log. But it is very cryptic, with 100 devices is a lot of noise.
I am totally desperate. Has somebody the same problem? Or an idea?
Have you upgraded your Home Assistant system during this period?
Do you have a Hue hub? If so you might reset several of the bulbs, both working and non-working and add them to the Hue Hub and check both the firmware there and their operation. I’m not sure, can ZHA upgrade Hue device firmware?
I don’t know if the firmware update helped. I have to wait some days or weeks now. And one little problem was, that I could not update all bulbs, because my bulbs were not all in the list. Let’s wait…
What you’re describing sounds like it’s more widespread, but on an individual basis this is exactly what I’ve experienced with individual bulbs dying. A long power-off period would frequently fix them for a while and if I didn’t shut them off (via a command, not actual power) they seemed to stay stable for quite a while. All of them slowly got worse until finally they became unusable and I tossed them. They also were all E26 (normal lightbulb) style and the oldest ones I had (so probably all older versions).
I’ve researched ways to extend electrical wires in walls and compiled the most effective methods:
Locate Electrical Wire: Use a stud detector with a live wire detector to locate the wire while the circuit is energized.
Safety Precautions: Isolate electricity at the consumer board before starting any work.
Plan for Wiring: New houses follow specific wiring plans, usually running cables 150 mm from the ceiling or corners.
Methods to Extend Wires:
Crimping: Use a crimping tool and the correct size crimp (e.g., blue crimp for 2.5 ㎟ cables).
Junction Connector Blocks: Screw terminals that need to be housed in a junction box for safety.
Lever Blocks (e.g., Wago): Easy to use, ideal for spaces like behind drywall.
Junction Box: While not always necessary, it’s advisable to use a junction box with crimp or screw blocks for safety and ease of repair.
Splicing Wires: This is possible but more time-consuming and complex compared to other methods.
Cost Considerations: The cost of relocating an electrical outlet varies by region. In the UK, outside of London, the typical rate is around £45 per hour.
DIY Electrical Work: It requires skill and understanding of building regulations. In most cases, it’s safer to hire a competent electrician.
Best Method: Preference varies, but lever blocks like Wago are popular for their ease of use and reliability.
Each method has its pros and cons, and the choice depends on the specific requirements of your project. Feel free to check out my post on 1st Electricians for more details on any of these methods!
Hi 1stelectricians, thanks for the answer and help. But to me, the most points doesn’t make sense, the power is ok, there is no problem with the power. Since I have replaced all my philips hue bulbs everything works very well. I guess the solution is to reduce these bulbs.
