timmmay: ... How are people finding them for reliability and safety? I'd like to get a couple, but want to make sure they're safe and aren't going to void my insurance if something goes wrong.
Seems to be very reliable for me. Charge my car for 6+hrs 3x a week for several months now. Now issues. Admittedly, I have not been awake long enough to feel how warm the plug is at the end of the charge cycle. ;-)
nic.wise: ... been looking for something low profile ... got a few tplink and wemo but they are huuuuuge….
It's still an adapter in between, so adds an additional 38mm to the height of the plug. As mentioned very early on on the thread, they are still too big to fit comfortably next to each other on a 2 plug power point.

SumnerBoy: ... So if you learnt the message format and structure you could control and monitor these using NodeRED or any other MQTT based platform?
These commands are published by the Tasmota team on Github. You could create your own NodeRED control or connected to any MQTT server.

So... I ordered 6 of these from them directly. Showed up the other day.
Set 3 up - 2 in the bedroom, to run raid mozzie repeller things. All good, tho the home assistant integration for ESP32 is a bit crap (can't rename the entities in bulk, works fine otherwise).
Set one up in the studio, also with a mozzie repeller thing (we get lots of mozzies, tho I don't need them until summer really). Went to reconfigure it today, can't find it on the network....
Go and look, sure, it's there and powered on. Well, the wall switch is on. Take out - bit of black dust around the sockets.... errrrrrm.....
Now, this could be:
a) device was DOA, tho it worked for a BIT as I had configured it and it was in HA previously
b) device took the hit for a faulty mozzie repeller (I've also thrown this out)
c) device tried to burn the studio down.
Going to be keeping a close eye on them from now, I think :)

I believe that b) was the cause. There was a short circuit in the connected device above 8A, so the circuit breaker did not trip because that was still OK for the line protection, but not for the Smart Plug relay, which lost the amperage race before. If you are so keen to clean it up and replace the relay, it could be reused again with a little luck. ;-)

Sorry for the late follow-up, but I'm not so sure that (b) was the cause. I've done a teardown of one of these myself to analyse and my guess is one of the following:
If I had to guess I'd say it was a surge. But I can pretty confidently say it wasn't the load on the plug that caused it. Why? Well, there are a couple of reasons:
Look closely at the image and both the charred circuit and burn marks indicate that the burning came from the top of the plug where the low voltage electronics are, not the bottom where the relay is. This is confirmed by what appear to be magic smoke exit wounds in the resistor:
And this matches with the melting around the active socket sheath on the cover:
That resistor is tapped directly off the active pin with a small circuit trace, so obviously not designed to carry much current, and it feeds the capacitive dropper which in turn feeds the low voltage circuitry. So something in that circuitry caused it to pull far more than it was supposed to through that resistor. It could have been the resistor itself failing, or something else.
Now IANAEE.... (would love for one to pitch in please) but it pays to realise that the live/active pin is not switched, neutral is. I'm not sure why they would have done that, it seems like a potential risk of electric shock if you think something is switched off and touch a live circuit (and that's why you always unplug your appliances before opening them, kids!). Anyway, you can see the big trace coming off the neutral pin and heading down to the relay, but there's no burn marks anywhere near that.
So maybe the mozzie repeller failed, but I highly doubt that it (or any excessive load) caused this. So yeah, my guess is either spike in voltage or component failure. As an aside they are rated at 16A, which is plenty, and I've had it on my 7.5A drier comfortably with no signs of overheating. It appears to have been a failure/short in the low voltage circuitry. I'd appreciate a second opinion on this. Happy to take photos of my now-easy-to-disassemble unit, or even drop one off if there's someone on the North Shore who would like to inspect it.
