I use a couple of Ewelink devices (hardware-equivalent Chinese clone of Sonoff S20 from AliExpress), reflashed with open source Tasmota firmware for the same purpose: remotely controlled power socket, with physical button, connected to WiFi, with HTTP web page and REST API for curl etc, firmware has MQTT support too; I have no idea about Alexa/Google integrations (likewise, I'm not interested in this feature), but the price is bargain, $10/each. Sonoff S26 clones are good for this purpose too, but UART port is easier to solder on S20 (larger one). Soldering UART port is necessary for reflashing to Tasmota, because stock firmware is utter crap.

- mkup 4y agoGround/PE pin is there, in passthrough mode at least (I'm using European/Schuko version). CE certification is obviously missing (in Conformité Européenne sense I mean, China Export is there), but hardware is 1:1 clone of Sonoff, so I don't worry too much about safety. The device looks like a mass produced in a factory, not a homemade solder in a garage. Temperature isn't hot, looks normal to me. ESP8266 chip is the same, the rest (a few Y caps, resistors, LEDs, pushbutton etc) I'm pretty sure is chinese crap anyway, regardless of whether this is Ewelink or genuine Sonoff. Local suppliers here in Ukraine are selling Ewelinks reflashed to Sonoff firmware as genuine Sonoffs anyway, so I see no point in spending more.
