Brand single, no. Brands pural… mostly yes.
-
Door/window: I’ve had folks (in North America) recommend the Linkind sensors, but I’ve had zero issues with Xiaomi Aqara (original and E1) and the Terncy DC-01 sensors.

Motion: Linkind again, plus Aqara (original and P1) and the mmWave FP1. If you want more than just motion the Develco “mini” is great - motion, light levels, and temperature.
-
Garage: I’d suggest looking at OpenGarage to hook up your existing opener.
-
Smoke alarms: Many smart smoke alarms are great at being smart, and terrible at detecting smoke. The only one I know of that’s actually good (based on actual testing) is Nest, or if you live somewhere that FireAngel sells their kit maybe try a hacked WiFi bridge.

Thermostat: Nest works

Doorbell: DIY it
