If they change components the properties in this test would also change so not sure I get your point other than that any test is useless since manufacturers change stuff without telling the buyers pr changing model numbers.
I have a bucket of devices which don’t do what I hoped they’d do because they were different from what the reviews said. And not just IoT unfortunately. Some do a better job at flagging these changes, some don’t.
But in the end taking the common case that the product is what it says on the box or that the changes have no impact on how it works, most people don’t care about the name of the chips. Not unless they are very keen on the tech and then there are more tech-oriented niche sites that might provide this.
I understand you, more information is better. I meant this article probably targets a different audience. Other articles [0] on the site focus on specific models and take this extra step, where the information is published or the devices can be easily explored. E.g. in that other article they mention the SNZB-02P has a Sensirion SHT40-AD1x.
There's nothing wrong with occasionally having these "roundup" articles targeting a larger audience.
I say this as someone who built multiple similar sensors around the house myself (except far less pretty or energy efficient than the commercial ones). Sometimes you just want a roundup and a quick comparison.
