Determining Zigbee 3.0

🛎️ Get Help Devices

I'm trying to figure out what in my zigbee network is 3.0 vs 1.2.
I've had 10-15 Outlets as the backbone of my zigbee network for about 5 years now and it's been basically solid. I use older repeater outlets to extend and I've always had devices drop off occassionally. maybe 1-2 every month or so.
I'm considering moving to newer zigbee 3.0 - I like the ThirdReality no power monitoring units, (4 pack for $35) but they do not seem to be 3.0 afaict.
Is there a giveaway to a device that it is 3.0? Besides the reading the box and making basic assumptions like 'original manufacture 2021)', I was exploring digging into my digi - and see the spec talks about an address identifier - but Digi XCTU doesn't show it on a known Zigbee 3.0 device. On 1.2 devices you don't see much:

Is there a coded way to 'see' 3.0 devices that HE helps identify? With the recent zigbee map tools I was hoping that might provide a lead - but not seeing it there or am I missing a bit?

I think that attribute 0x0000 (ZCL Version) of Zigbee cluster 0x0000 (Generic Cluster) can be used to determine this, I might be wrong though.

On the 3 random devices I just checked, all have value 0x03 for this attribute. I used my Knockturn Alley driver to retrieve the info from the devices, I don't know if there is an easier way to do this.

There is no zigbee 2.0, there is 1.2 and 3.0

I actually knew that. I stand corrected for my dire mistake.
