This article covers how to handle MEATER Block where the probes have differing firmware versions.
You can find your probe's firmware version directly in the MEATER app. Simply open the app, navigate to the Connection Details screen, and select the probe you'd like to check.
Can I update my probe's firmware?
Probe firmware cannot be updated after production — but the good news is that this won't affect your cooking experience in any way. There is no functional difference between probe firmware versions. The firmware simply indicates when your probe was manufactured, so if you've purchased your MEATER recently, your probe may show a "newer" firmware version compared to an older one, but you won't notice any difference in performance.
