You asked & several replied. I too want to share. I don’t use a traditional looking Smart plug. Yes, these are WiFi and don’t require a hub. Straight WiFi. These are unique and the formal name is Basic RFR2, aka RFR2. Aside from the routine, app-controlled, Alexa-controlled, Google-controlled, manually controlled, and on a schedule controlled, they have still one more feature a RF signal, using generic 433 MHz remote, (such as also linked), you can just press an assigned button to toggle them off and on. The remote I like as 8 buttons <$7 (unheard of). But I don’t simply use these on my Wyze camera. I used them on: lamps, TVs, ceiling fans, coffee pot, fish pond pump, printer, 3D printer, shop vac, computer monitors, porch light, shop lights, cell phone charger, Echo Dots and Echo Shows. Even my cable modem and main router. (Yes, the router.)
These smart plugs have a “Last State” feature. A On, off or whatever last state, position. If it was on and power is lost, when power is restored, turns itself back on. Also stores the schedule 24/7 locally, so does not need cloud connection to trigger a shutdown/restart or start up. For instance, on a cable modem or a router, want to remotely restart it? Pick a time as soon as 3-5 minute in the future or whenever, to shutdown, and 1+ minutes after that to start up, and you in essence have restarted it Another example. Its 5 pm, I want to restart cable modem, set schedule for 5:05 pm shutdown and 5:07 pm start up. Save the schedule and it happens. I have one on my router. All I had to do was create a schedule to shutdown and start up AND add the Last State as “On”. Then when I plugged the smart plug into the power, it read the last state and started, EVEN THOUGH, it had not booted yet to the Internet, it already knew via the Last state was “On”, so it continued to seek an IP Addresses and start the WiFi network.
EVEN BETTER, with the RF feature, I can press a/then generic remote’s button to toggle it on and off, without unplugged it and plugging it back in. (Most routers these days don’t have an on/off switch.)
If you look at these WiFi plugs you ask yourself, where’s the two or three prongs to plug it in. Its an inline adapter. It uses no ground, just load and neutral. I buy 3’-12’ two prong extension cords and cut the cord and attach the male end to the input and 3 outlet end to the output. In a few places the extra bulk of wire is inconvenient, but still worth adjusting. On my TVs, I just cut the TV cord and put the adapter inline since the cord had its own smaller female end going into the TV. Then I have an 8 button remote bedside and couch side to turn off lamps and TV. (They also have a RF version of a wall switch called the TX series and I have them in all walls for overhead lights and use the remote to turn on/off.
If you don’t like the form factor, they have a standard WiFi Smart Plug called the Sonoff S31 or Amazon that has all the features I described EXCEPT RF. No, RF, so I don’t use them any more, but they store the schedule locally.
I buy these from the China factory and are cheaper than Amazon.
See these links. These products use an app called eWelink, that just keeps getting better and better. They also have a webportal for accessing and using the devices.
One of my favorite features of Sonoff devices, you can also control them with NFC tags that you program very easily via the eWelink app. Most NFC to device control programming use third party app like NFC Tools and some backdoor binding method. These are simply program the device in the eWelink app and it works - even with iPhone. Ever used NFC tags? Check them out on YouTube.
