These were a lifesaver when I had Xfinity and their useless tech support couldn't figure out why they were dropping signal on my modem.

You need to compile your own build of Tasmota to enable the PING command, but I had it so it would ping Google every 5 minutes to determine whether I had internet or not. If it was down, it would cycle the outlet the modem was connected to.

The scripting language in Tasmota is robust enough that I was able to have it add time between flipping the power if it had consecutive unsuccessful ping/flip sequences, thus putting less strain on the relay.

The only downside (possible upside if you like auditory queues) is that the relays are pretty loud. They definitely won't work well in any quiet setting.

You can with SwitchBot plugs. I set the threshold for 1 watt for power tool chargers. Hope this helps.

It's relevant if you are a true slickdealer and don't even need the product.

I can happily confirm that the set I just received is now running Tasmota!

Flashed OTA with Tuya Convert and all is well. I've even given them static IP's and (of course) incorporated them into another in-home (never mind US-based) ecosystem.
Is there a guide you followed? Do all functions work? i.e. individual outlet control, physical button, accurate energy monitor. Any guides I've found seem to only manage 2 of these.

At the risk of massive oversimplification, it's like equipping them with their own very simple web server/interface, allowing both direct interaction (as in via ANY browser) and integration with any number of apps/ecosystems via open standards.

I stick [almostly] entirely to Zigbee (and the like) simply because I can use in-home, non-internet/China based servers. That whole marketing benefit of "no hub required" basically translates to "these devices connect via wifi to a server in a country that requires companies to share with the [anti-US] government". In an even more important (and less paranoid sounding) way, it also means I can control my house even if my access to the internet is interrupted.
Used to have bunches of wifi inwall swithes. Move ~90 percent slowly with hubitat and zwave😙. No time to tweak esp flashing,mqtt and other api connections.

Well still having first gen philips hue🤣. And some wifi switches that integrated to home-theater automation. I keep it as is till broken or not functional properly 😝

Does this work with 220v if I use the plug adapter.

I have a couple of these. They work fine but I wish they had a screw to attach them to the outlet more firmly. Minor gripe though. There is also a smaller version with the same 3/1 outlet setup which does have a screw attachment that is on sale 2 for 20.
Thanks!
Looks like that one does not have energy monitoring, which I rarely use even with running a whole house monitor. Plugs are also spaced apart much better.

Currently shows a $3 coupon, bringing it down to $16.99 for 2.

As long as it's under 15 Amps for all the outlets combined but you can find a lot better options than one of these.
Like what? Would a Kasa smart plug mini be good? First result on Amazon

I like the automation piece but curious what people use the energy monitoring function for? And while it would be kinda ironic, does the energy monitoring function in of itself draw more electricity?!

Don't buy these.

They're a fire hazard. I posted a pic of the insides in a previous thread.


Edit: Nevermind, I think bought this version:

I can't find my photo but it looks similar to this amazon review photo.
Erm…even if it wasn't this exact model, if the brand has been known to be unsafe, then…

Individual plug monitors leave out anything not connected, so not as useful here.

Instead, we use a $20 Black & Decker EM100B Power Monitor for the whole house. It has one part that attaches over the outside of the electric meter (even after they replaced with a smart meter) and senses the meter led in real time. On the Electric company list of approved devices. The other part is a small wireless remote screen that shows data. Uses no power except rechargeable AA batteries. This allows us to see instantly any changes in devices throughout the entire home, 110 and 220v and is updated about every second. Also is programable with your area's electricity tier charges. The remote default screen always shows running total estimate of what your electric bill will be, what tier you are currently on and how much $0.00 / hr (or kW) you are currently using in real time ($0.28 /hr as I type this, $293.48 estimated month bill). After using about 12 years, it is around 98% accurate. An example of usefulness: Upgraded pool pump and saw a 3 cent per hour savings ($6 a month) compared to old pump. However, once you have the data, you know longer need to know how much something uses. Constantly running bill estimate feature though is something I couldn't live without.

I got them today too but I didn't see the nightlight. How do you turn on the nightlight?

My solution for this is a smart plug with tasmota firmware on it.
Secondly I have a raspberry pi that controls all my 3d printing with octoprint. It has plugins including tasmota plugin that controls the power, I can turn it on remotely, and then start a print, and I have it set to power it down about 30 mins after print is done (to let it cool down). Other plugins I use include obico (formerly spaghetti detective) which watches for prints going haywire and I can check video stream from it anytime anywhere, a plugin to monitor filament usage and can tell me how much I have left on a spool, and others.
Do you happen to have the tasmoda template? I cant seem to get the power monitoring in HA?

Anybody happen to have one of these and check the quiescent current both when the plugs are turned on and off? Between the always active wifi and 3 individual relays it could be as high as several watts when all relays are active, which is less than ideal if your primary goal is power savings.
Quote from SkillfulLinen237 :

So I decided to answer my own question...with all relays off and wifi connected it draws 0.4W with a power factor of 0.3, and each active relay adds about 0.5W. With everything active it sits at 1.8 to 1.9W and a power factor of 0.45. It's not terrible but could be better.

As for the energy monitoring drawing more power, not really. The amount of power it takes to add in energy monitoring when you already have wifi and relay control of individual outlets is miniscule, on the order of microwatts or even nanowatts most likely.
