Neudy:
I can pair the button with my hub and it works well (single click, double click, etc.), but it always disconnects after a while (sometimes its one hour, sometimes two hours) and i have to do the pairing procedure again. Is there some trick to fix this?
Are you using any ZigBee devices that are mains-powered (plugged into a wall socket)?
If yes, then here’s the likely reason why:

As for Xiaomi / Aqara devices dropping their connection, the number one probable reason for this is due to other ZigBee devices on the network acting as ZigBee repeaters that are incompatible with Xiaomi / Aqara’s non-standard method of maintaining their connection.
Most ZigBee devices that are mains-powered (plugged into a wall socket) are repeaters (with the exception of some smart bulbs such as Sengled). The only ZigBee repeater devices confirmed to work with Xiaomi / Aqara devices are XBee Zigbee modules (see here for more info), IKEA Tradfri Outlet / Bulbs, and user iharyadi’s custom ZigBee multi-sensor repeater solution . Also in theory Xiaomi / Aqara’s own mains-powered devices like the Xiaomi Smart Plug or the Aqara Wired Smart Wall Switches should work as compatible repeaters, but I don’t own any myself and haven’t read enough reports by users to know for sure.
Personally, the only repeaters I use are some XBee modules and an IKEA Tradfri Outlet, and I almost never see my Xiaomi / Aqara ZigBee devices drop off the network. Full disclosure: I have moved nearly all of my home automation setup to a Hubitat hub, but the same issues with incompatible repeaters apply there as well. However, I am doing frequent testing with my 40+ Xiaomi / Aqara devices on the SmartThings platform in order to improve and update the SmartThings device handlers (DTHs).
Note that your Aqara Temp-Humidity sensor could have no issues because it is connected directly to your SmartThings Hub, rather than through a ZigBee repeater device.
Either way, I highly recommend having a look at this thread I started on the forums of another hub, Hubitat, which works very similarly to a SmartThings Hub and has the same potential for issues with Xiaomi / Aqara devices:
NOTE: Although many users have had great success using them, Xiaomi / Aqara ZigBee devices are NOT officially supported or guaranteed to work on the Hubitat Elevation platform. Because of their small size, simple design, and relatively low price,...
