Zigbee Delivery Failed

Written By Michael Curtis

Recently I had an issue with one of my automations. It would not shutdown the devices in one of my rooms. It was meant to turn off the two lights, turn off a smart socket, close the blind and turn off the AppleTV.

The first sign of trouble was the IKEA blind was offline. I reset the blind by disconnecting the battery. That corrected that problem. The automation was still returning this error - Error: Failed to send request: Failed to deliver message: <sl_Status.ZIGBEE_DELIVERY_FAILED: 3074>

I asked on Mastodon for some help and was asked if any devices had been removed. None had, but it did point me in the right direction. I tried to control the devices manually, and found one of the bulbs did not respond. After removing the bulb from the socket and screwing it back in again, the bulb was responsive and the automation worked as expected.

My introduction to computers started at my middle school in 1981 when our maths teacher brought in a ZX80. That led the computer club being founded and using a Research Machine 380Z

My first computer was a 48K ZX Spectrum which I loved to programme. Once I left school I worked as a photocopier engineer, then a fax engineer and finally moving on the Apple computers.

For the next 30 years I worked as a system administrator. I now work in the cyber security industry as a Sophos Professional Services consultant
