(Some) Wemo devices gone after 0.94?

Seems like I lost a bunch of Wemo switches in the 0.94 update. Some are there! Some (mostly newer Wemo Minis) are not. I’ve got default_config: on, I’ve got wemo: on in the config as well. Has anyone else seen or dealt with this?

I’m seeing this too but only Wemo Link devices, i.e. Wemo LEDS

I had the same experience and fixed it by entering the following in configuration.yaml

  discovery: true

Perhaps discovery is false by default in 0.94


I’m still having the same issue. Have tried multiple combinations of ssdp:, discovery: and wemo: in the configuration.yaml, but some reason HA failes to discover my WeMo motion sensor. WeMo switches seems to work fine.

This issue is only happening on one wemo dimmer I have, and it’s one that I have had an issue with since I purchased it back in november. Up until now I have been able to use it while setting all my wemo devices statically, but now, after .94.*, if they are set static they are not usable. If I remove the static line and address for this problematic dimmer in the config, then every device except the wemo dimmer works. I have one other dimmer on my network that still works perfectly, and I don’t see anything in the logs as far as why this doesn’t work.

I might have some time this weekend to dig in further into troubleshooting, but without any errors in the log I wont really know where to start.

Does anyone else see any errors in their logs related to the wemo component?

Just kidding, finally got it to give me an error:

Any way I can get you (and anyone else) to post your error logs?

I am running 98.5 after rebuilding from an 88.4 crash and burn Hassio on Rpi. Since I installed it, all my fauxmo wemo switches are getting an error box “failed to.call swit_turnon.no element found: line 1 column 0” and the error trace looks like:

I have no clue what the trace is trying to tell me but the switches will actually work. I get the error when I turn them on or off (switch.turnoff.no element…)

Any thoughts on what to do about this? I’ve rebooted many times but it persists.

Thanks in advance.
