The !electronics@discuss.tchncs.de community would be a better fit for this post IMO

That said this looks interesting, and seems really competitively priced when compared to other similar thermal cameras like the Flir One Gen 3. This measures a very wide temperature range too, from -20°C to 400°C within ±2°C, whereas the Gen 3 tops out at 120°C.

The 80x62 resolution is OK for this application IMO, the Gen 3 is similar at 80x60.

I wouldn't go recommending one of these to a "casual" user though, it's very much a development product. Non-casual users could probably 3d print a case and get on just fine with the demo apps IMO, and for those users this would probably worth its weight in gold, given how expensive thermal imaging usually is.

Given how closely its priced to radar presence sensors like the Aqara FP2, and the inclusion of I2C for comms, I think this is going to have some appeal to DIY home automation enthusiasts too, especially if it gets supported by open source projects like ESPHome

Edit: I should also mention that there are much cheaper options on sites like AliExpress if you just want something cheap to use via usb-c - the advantages this sensor has are heavily dev focused IMO and might not make sense for most users (e.g. documentation, i2c comms, product integration support)
