Yes, these things have come up quite a few times. Regarding Radon there are unfortunately no 3rd party sensor modules available that we know off (and are reasonably priced). If you know any, please let us know.

Regarding PoE, we have made a survey some time ago and less than 5% of the users were interested in PoE. However, the hardware integration is not straight forward and it would increase the price of the unit for all customers. This is the main reason we did not do it yet.

However our open hardware has an extension plug and this could be an excellent community project for somebody to develop this as an extension card and then share the design.

So fully recognizing upfront my own bias towards this feature, and that lack of immediate interest makes something a business risk regardless of how it might turn out over time. Still, just 2 cents towards the long term:

>Regarding PoE, we have made a survey some time ago and less than 5% of the users were interested in PoE

1. I'm not sure surveys are that useful for features a lot of users aren't aware of or might have outdated views on. I think a better survey would be on whether users wanted ethernet at all, because that's the only real differentiator there in an age where a basic PoE+ switch can be had for $55. If it's already going to be on a hardline, then having it be powered that way too is ultra useful and zero extra work. Ethernet is also something people can do without being electricians. There is a bit of chicken/egg challenge with features like that where not many people know because there isn't much stuff.

2. I hope you're normalizing to some degree for purchase volume. 5% of customers isn't the same as 5% of sales.

That said I certainly wouldn't want to see you face any challenges over something like that and your reasons are fair enough. It is just a bit of a bummer to not have more options on that front. But the native HA integration added back in June with no firmware flash already sold me on a bunch of AirGradients anyway and was much more important! Thank you so much for that.

I am not ruling it out in the long term. I actually also would love to have a wired Ethernet connection and if we grow further we might very well come to the point where the 5% really matter and we have more resources available to develop it.

Why not just use Airthings, don't use their service, and own your data.

They say in the license if you use their service (i.e. you upload your data to them) they own it. But if you don't, you own it. Seems fair to give them their data if they are going to store it for you and provide you an app and website to view it.

They publish a github repo to let you download direct from airthings (not using anything cloud) and graph it with graphana or whatever you want.

This isn't the case for their newer products afaict-- with the ViewPlus (which is what I have) you _must_ go through their cloud offering in order to get your data.

I do not want to roundtrip for something that shouldn't have left my house in the first place. Their older products allowed me to keep it local, why shouldn't their newer ones?
