I read it different
Only 2019 has also a Pro 2 Core 1 GB
Others where always 1 Core 512MB
The last year(s) only the Pro (2C 1GB) was available
The Microphone was already disabled by a software update. Only missing from a 2016 or 2018 model would be the NFC in the Homey Top.
So best case you double the CPU capacity and Memory
Check it in Settings - General
