Wemo Light Bulbs Discovery Error

Configuration
1

Hi all,

New member here, I’ve been getting started with Home Assistant over the last few days.

I’ve been getting a few devices together so that I can start trying things out.

Unfortunately my existing LightwaveRF dimmer switches aren’t currently supported by HA, so I picked up a WeMo Lighting Starter Pack (2 x bulbs and 1 x Link) and an Echo Dot to start trying out some voice controlled lamps through HA.

The Echo Dot seems to communicate fine with Home Assistant, and I’ve successfully used my voice to instruct HA to turn off my smart tv.

I am having a problem with the WeMo bulbs though:

I added the WeMo Link to my wifi network, and paired the 2 bulbs to the Link.

I have tried adding the following combinations of entries to my configuration.yaml file:

1. Just auto discovery

discovery:

2. Auto discovery AND the wemo component

discovery:  

wemo:

3. Auto discovery AND the wemo component with IP Address of my Link

discovery:
wemo:
  static:
    - 100.124.245.26

Regardless of the configuration, I get the following error in my home-assistant.log file:

Does anyone have an idea of what I might be doing wrong?

Surely methods 1 and 2 should have worked fine on their own?

Thanks in advance

Try adding the IP address for your hub and the ip address for each component attached under static. Worked for someone a couple of days ago when discovery wasn’t working.

Thanks for the response!

Turns out my WeMo link is faulty, it dropped off the WiFi and won’t reconnect, even after factory resetting the device and reattempting the initial set up. I am going to return and order a replacement.

I will certainly try your suggestion when the replacement arrives!
