I have never had or used a smart plug. Probably should in case I can't get up. I have a very bad arthritis knee and using a cane since last December. I can walk in my apartment without it, but I always take it outside with me to use. If I ever get a total knee replacement, I would need much more help than a smart plug can give me. It is actually good for me to get up often to keep the joints moving.
