Aeotec Motion, Button, Smart Switch 7 and Multipupose sensors are available on Amazon (US)

Notice from Aeotec:
New product. Fresh stock. Limited supplies.

The shortage of chips keeps automation products barely available. For a short time only, the USA has stock of Smart Home Hub, Button, Motion Sensor, Multipurpose Sensor, and Smart Switch 7.

I am still kicking myself when BestBuy had these things on sale when Samsung was clearing out their branded hardware. I picked up a lot of buttons but should have got the motions also since they were only $19 each.

Button is already unavailable.
