Existing Aqara Zigbee Contacts or New Thread Contacts for Expansion?
Expansion is a good time to review the network, but it is not a reason to discard working sensors automatically. Compare the next opening and the platform you want to use.
Keep a stable base in view
If the current hub supports your installed sensors and needed rules, continuing with a verified combination may simplify support. Record any real limitation before treating a protocol change as a necessary upgrade.
Compare new requirements
A Thread contact has different infrastructure needs from a Zigbee accessory. Include any missing controller or border router and its setup, rather than comparing only the price of the small sensor itself.
Decide by the finished routine
Ask to see the opening state and intended action in the daily app. Choose the configuration that gives the household a dependable routine with a clear path for later support.
