I was wondering if someone else is using the wemo bindings and having problem with it? Mine always seems to stop updating until I trigger something. For instance, right now I have 2 light open but only one show on in openhab. If I click my master send off, it will turn it off, but because of that rules aren’t fired. Once I update all switch, they will work for a random set of time.
I have tried changing my server 3 times (from a physical machine to a docker under ubuntu to a docker into unraid), I have changed my network from an asus router to a pfsense and unifi network, nothing work.
UPNP is enabled in pfsense and working fine for anything else.
I would also suggest denying Internet access to your Wemo switches. It was long ago, but I believe that mine only became reliable after I cut them off from the Wemo servers.
I replaced almost all of them with TP-Link Kasa switches, and have only kept my Wemo Motion and Wemo Maker. I have no problems with either of them.
