Your recommendation for smart plug (sh.itjust.works)

I'm tinkering with our ventilation over-pressure function in combination with an inline fan I run when 3D printing or soldering, to get the fumes and particulates out while simultaneously not creating a massive vacuum inside. The plan is to control it with MQTT from HA to a PLC that controls the ventilation via RS-485.

Therefore I'm looking for a simple but clean looking smart plug that I can integrate with HA to let me know when the fan is on (pulling power, actual wattage is irrelevant) to automatically enable this function.

I know Sonoff makes some, but I always prefer personal advice over random search results.
Preferably Zigbee or WiFi (offline) as I don't have any Matter/Z-wave hub/dongle. Compact design and black would be nice, but not a must. Stability and ease of setup matters more than added functionality.

Does anyone have any personal experience to share?
I'm grateful if you do. Thanks!

I have liked the Sonoffs with Tasmota for many years. But recently, they use different chips that make this impossible.

So I ordered my last ones from athom.com, because they sell them preinstalled with Tasmota (or other firmware).

I need to read more up on athom. Seems like a cool store! Cheers

I have a bunch of smart plugs from Athom too, and they're good. Unfortunately I chose those with WiFi back then. Tasmota is fine, and reliable too, but nowadays I prefer ZigBee for most of my home automation.

I have a few of the discontinued old version TRÅDFRI plugs from IKEA too, since it's ZigBee, and one of them makes weird clicking noises sometimes, almost as if the relay is extremely quickly switching on and off for no reason. Perhaps the new IKEA plugs are better quality.
