I’ve had nothing but problems with the Wemo’s I have. In the process of getting rid of them.
The new account requirements seems to force you to have all your Wemo’s exposed to the cloud. With the existing system, you had the option to not cloud-enable, but doesn’t seem to be the case now.
I’m dumping all my Wemos because of the poor reliability, dropped connection that requires physically power cycle to reconnect to the network, but mostly security.
In the Wemo app I see other Wemo plugs that do not belong to me. Apparently this is a long-standing problem that Wemo refuses to acknowledge or fix. Probably the new account thing is their attempt finally at a solution by changing how their entire cloud system works, but I’m not waiting around.
Note: Ikea switches are garbage. They use Zigbee so you must have an Ikea bridge but worse, Ikea uses a non-standard version of Zigbee and requires a “Steering device” to setup each of their other devices.
Worst thing about their smart plugs is they have no physical switch. Can’t turn the attached device on or off with an actual switch unlike every other smart plug made. Also, they are large in size and ugly.
Disclaimer: I only use these types of smart switches for lab bench and convenience. None are reliable enough for my clients or professional installations, YMMV.
I have had good results with ConnectSense and others are reporting their are happy with Vocolink. Both are fully HomeKit certified.
If you don’t need HomeKit, the Wyze smart plugs are an incredible deal at only $7.50 each and I have found them to be the most reliable of all the Wi-Fi plugs I have tested. Shame they don’t do any HomeKit. I use them for the cable box and other things where I actually want to hide them from HomeKit so they don’t get flipped by mistake. In this case, needing a special app and login (the Wyze app) provides some safety by obscurity.
HomeKit does not have any ability to restrict access to some devices, so if you have kids or family members that also use your HomeKit setup, you need to be careful how you are deploying smart plugs.
