Zigbee motion sensor and button recommendation

Hi all,
I just build a simple automation to be notices when my cat appears inf from to my door wanting to get in.
The motion sensor catch the cat presenza and the button is useful to disable/enable the notice message when I need to go out.
I used Xiaomi Aqara products but I’m bound to say the are a little bit unpredictable because the tend to stay bound to first router they were paired.
So I’m looking for more reliable products that can works fine with Deconz and my Conbee II with an high sensitivity and good roaming capability from a router to another.
Is there anything like this outside?

Thanks a lot
