@april.brandt had mentioned in another thread that she had retired some Peanut Plugs to her HA device "Drawer of Shame". That reminded me that I have many such devices and I thought it might be interesting to see what devices others have retired to their Drawer of Shame. It also might be helpful to others that are having issues with certain devices. I'll start.
Ivee home assistant which was an early attempt to create what Amazon eventually accomplished with Echo. It was horrible and was probably the second most frustrating device that I ever attempted to include in my home automation system.
Next up was a Skybell doorbell. I know that they have improved but there is a reason that Ring has thrived and Skybell is barely known. For me, Skybell only worked intermittently and their customer service was some of the worst I have ever dealt with. When my version 1 Skybell fell off my network and I couldn't get it reconnected, I called Skybell and the informed me that they no longer supported that version and they have removed any of those devices from their system if they fall off your network. I was just SOL and they offered me a 20 % coupon if I would purchase their next version half working device. NEVER.
Any hinge sensor that I have ever tried. NYCE worked the best but was fragile. The GE hinge sensor is worse, I have one of each in my Drawer of Shame.
Strips Sensative with a non-replaceable battery that is supposed to last 10 years but lasted less than 10 weeks.
Linear Z-Wave Garage door openers. Two of them. They would not stay connected, opened on their own and fell off the mesh weekly. I understand that the newer Z-Wave Plus version is much better.
Schlage Z-Wave deadbolts. Non Z Wave plus. They were very problematic on the Iris platform not unlike the stories that I have read on this forum. When I moved, I left them in the house and started over with mostly Zigbee locks. Best move ever.
So, what's in your drawer of shame?
