Forum member "ct" where are you.....?

Are you referring to ctwx?
I don't believe so.
The person I'm referring to has the capability to use (and I think does) the SHT35 with a VP2, or with something. He gets the i2c thingy so other sensors could potentially be used.
I sent him a pm, but he doesn't post much.

Look, lots of people have given freely of their time, expertise and money to try to understand and solve a problem that's not their fault. Some of us have thousands invested in a company that, apparently, thinks it can bait and switch us with impunity.

Given the circumstances, it's not a straight line to the answer. We don't have the same testing facilities as the manufacturer. We have to do our best with what we have. The situation, unfortunately, is still evolving on a trial and error basis.

Yep can't even calculate the time and money I've put in and continue to put in to try to figure it out.  Seems like until Davis ditches this Digital Sbus protocol for the I2C they have us by the you know what. Unless someone here wants to try to build there own ISS transmitter that has a I2C microcontroller I don't see a whole lot of other options other than switching these sensors out every year or so.

Would love to try these sensors out as they look promising but alas, wrong protocol.

Looks like this one might work best in high humidity environments.

Here is the data sheet- https://www.ist-ag.com/sites/default/files/DHHYT221_E.pdf

Application notes- https://www.ist-ag.com/sites/default/files/AHHYTM_E.pdf

Actually mentions one of the typical applications for the HYT221 for measuring humidity in saunas lol! Wonder how it recovers afterwards though?

Maybe kcidwx will get one of those sensors and put it in his humidity chamber and see how it does.

Donít think so but Iím not an electronics expert.

Do you have the SHT-31 sensor too? If so, how does it compare to the SHT-35 in terms of humidity?  There are some of us who believes that the SHT-31 humidity sensor does not operate within specs and has a wet bias in mid range humidities and a dry bias on the high end.

Here is a thread discussing the SHT-31
