You would probably have more luck catching the developer's attention and others that use the same devices in the release post. You could also search the post for references to WN32. In a short read, I did see that the app only appears to allow one outdoor sensor. But I did not read much further.
I know from the error message that it only allows one outdoor sensor. What I'm saying is that this should not be the case. If obviously found the device and knows what it is. I don't see any reason to block this information from HE.
When I search the topic you referenced, and then click on the matches, I don't get to see the matching posts, I see other non-matching posts. I don't know if this is a problem with my browser (Firefox/Windows-10) or the web page. Maybe the web site is getting a bit lost on a topic with 2,000 posts.
I have been on this forum for less than 2 weeks, and the help I have received has been fantastic. However, I have been on other forums for more years than I can count and the rules on other forums tend to be that if you have a specific problem, you start a new topic, rather than add to one that has been going on for years and has 2,000 posts.
Are you saying that the practice here is to lump everything to do with one app in one single topic?
For community-developed apps & drivers, yes. There aren't running threads for stock/native apps & drivers, so creating a new post for those questions is the way to go.
For community-developed stuff, keeping questions & responses in one place helps consolidate all that info, and posting there will most effectively attract the attention of the respective developer and fellow active users.
Wasn't saying you have to. But was also saying that you would likely get faster repsonse and resolution. Also, you might find that the questions you have were already answered (again.... I did not read thoroughly. I just saw mention of it. However, I do not have the WN32 and I am not the developer, so my input would be moot)
It also helps because some things (like Ecowitt) have multiple different community-developed drivers, and there might be differences in how they handle such things. If you make a general question, that can delay a good result in cases where people need to figure out whose driver you are using in the first place.
