Hello, I recently bought a door sensor and motion sensor from simplisafe, I then found out I needed Simplisafe base/hub to setup the sensors. I’m pretty new to the home assistant world and I was wondering if there is door sensor on market that doesnt need a another hub (other then home assistant)
The only door/window sensors available without some kind of ‘hub’ are wifi sensors (your access-point act as ‘hub’), but they are notorious slow. Same for motion sensors. Unless you use wired sensors, but these still need to be attached to something.
A Zigbee stick as the CC2531 can be bought for as low as €4 ( it is far from the best Zigbee option, but very affordable. A Sonoff Zigbee bridge costs about €15, but you might need to add the cost for a programmer (€4) to flash it.
A Sonoff Rf Bridge for use with 433Mhz devices is 12€ (again you might need to add the cost for a programmer (€4) to flash it.)
