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!
