Excellent product! I use SONOFF software or FREERTOS, both work great!

These boards are high quality, are well packaged and ship quickly. Their on line support is superb and I will buy again. If you put SONOFF on them, Home Assistant can activate as you require - awesome DIY relay boards!

Great little relay controller.

Like I said in the description it's a great little board. I use it for an automated plant watering system and keeping a bird bath filled. My only suggestion is adding or pre-purchasing ESP32's with a U.FL Connector for an external antenna. The short distance wifi is the only drawback of the board.
