Yes, upgrade kits will then also be available middle of next week.

If I wanted to get the appropriate female connector for the PMS5003 to mount on the board anyone know what that connector is? I see @awh and @Fenaer have them so maybe they can point me to where to get them?

The kit already comes with it, but if you wanted to get one separately then it’s listed as “JST Connector 1.25mm 8 Pin”.
My kit did not have the board connector. I will try and source one. Thanks for the quick response!
JST Connector 1.25mm 8 Pin is correct. Just make sure you get the through-hole version. They also have SMD versions.
Does the default Airgradient v3 firmware that is installable via the web flashing on the v3 instructions page come with TVOC enabled in the code?
I tried connecting the SGP30 to the v3 pcb without the SHT30 connected and it still said TVOC: 0.
Yes it should work. Did you remove the pull up resistors on the SHT as per built instructions?
I haven’t removed the resistors yet as I was hoping I could test the SGP30 by removing the SHT30 first and only having the SGP30 connected.
Also, is there an updated link for the v2 basic diy enclosure 3d files? The link at The AirGradient DIY Sensor Enclosure does not work anymore.
It might work without the SHT but probably better to remove the pull ups and try.
By the way the SGP30 needs some warm up time so it’s normally that it’s 0 for a few hours. Then try to make some chemicals eg with ethanol to see if it reacts.
I will check the link for the 3d drawings tomorrow. We still have them but I updated the website recently and maybe a mistake happened.
Links should work now again.
Something went wrong removing those resisters. They are gone, but now I am not getting any readings from the SHT30. Temp and Humidity are 0 (via serial console).
I poked at it with a meter and I don’t see any shorts, but I’m trying to look up a schematic for that module so I can get a better idea what I’m looking for.
I’m having a hell of a time desoldering the parts from v2 for the upgrade kit… Anyone have any tips?
I’m fairly sure I’ve destroyed both S8s, both SHP30s, and both Wemos modules with too much heat. I really would just recommend buying new for anyone still considering taking this on…
i build the new kit today. works good! i edited the code quite a bit to get the measurements into prometheus.
i also have the old kit (the now basic) with a added sgp30 so i can compare those measurements with the new kit. they should be the same but with the different pcb and case they might be better.
i really like the larger screen. more info at once.
After fiddling with it a bit, I got the SHT30 module working again. I still see 0 on the tvoc sensor though. I will poke around with it more today.
I’m pretty sure I’ve destroyed my SHT30 when desoldering the pullup resistors, now although it can be detected on the bus, it only reports 0. On the plus side, TVOC is reporting fine now.
I really want to get temp and TVOC working. Is there an alternative temp/hum sensor that would work alongside the SGP30?
It is really a problem of the number of i2c devices on the bus and the esp8266 has only one bus.
You can try and find a temperature sensor that does not use i2c but I would rather recommend to get a new SHT and try again.
The TVOC sensor needs time to burn in. Then after a few hours you can use some ethanol and see if it spikes.
Just want to let you know that we are now selling the kits again in our online shop.

is there any guides for Home assistant integration?
I’m using ESPHome.
