any updated version for the newAirGradient Pro (v3)?

[DariBer]

Hi,

As there is a new updated version of AirGradient, Pro v3, I wonder if you will update your ESPHome so that it can be used with the new version and then have the data in Home Assistant.

/D

[ajfriesen]

I guess you are talking about this?

https://www.airgradient.com/open-airgradient/blog/airgradient-diy-pro-instructions/

I don't own the new version so I can not verify.

But looking briefly at this it seems it's almost the same except a pin layout changed for one sensor.

So you may need to change that but other than that this should work almost the same.
Maybe a few adjustments.

If you happen to have one I will accept a PR for the new version.🙃

[ajfriesen]

Looks like I will get a pro kit as well.
Will come back to you when this arrives.

[DariBer]

Nice! I think the new Pro (version 3 or what version it is) is a great product to get data about the air quality

[dsanner]

display:
external_vcc: true

weirdly seemed to fix the communication problem with sht3xd

I'm very confused on why there's both air-gradient-pro-diy.yaml and air-gradient-pro-presoldered.yaml. As far as I can tell, the hardware is the same; the only difference being that one is pre-assembled.
Based on the discussion here, it sounds like this stemmed from different versions of the hardware/PCB, rather than the difference between DIY and pre-soldered. Is that right?
Currently, the -diy.yaml seems to have some more recent updates, which weren't made to the-presoldered.yaml version. So wouldn't it be better to just have one file for the AirGradient Pro (or create separate files based on the PCB version)?

[Motya-HA]

I have the same question: why -diy.yaml is different from -presoldered.yaml?

[Ixian]

Thanks for the updates! I have it semi-working with my Pro kit 3 - TVOC doesn't work (even with the changes suggested above) and for some reason it's not communicating with the SenseAir S8 but maybe that is a hardware problem.

Quick question: Is there a way to flip the display text? With the Pro kit, it can only be soldered in one orientation and with this ESPHome config that makes the display upside down.
Edit: For anyone else who runs in to it, rotating the display is as simple as putting:

rotation: 180°

In the Display: section. Substituting 180 for 45 or 90 depending on which way you want to rotate it.

Hey all, I'm using the Pro DIY kit (Thanks to @ajfriesen and @handro123 for posting your configs). The unit runs for 3-5 days and then eventually freezes and stops sending data (and display freezes)... In the logs I see things like:

Would appreciate some pointers on what the best troubleshooting steps may be. Can share my ESPHome config for this device if it's appropriate to do so here.

[ajfriesen]

Sorry, but I can not help here.
I think going to the esphome reddit or discord is a better way of tackling this problem.

[ajfriesen]

I have updated the repo to represent the air gradient pro presoldered version because that is what I have got at hand.

[DariBer]

great!

Is the "SGP4x AirGradient TVOC Module" included in you Air Gradient Pro? Does your code have support for the TVOC module?

[ajfriesen]

No, I dont own this sensor.
I am not even sure were to connect this sensor.
I know you can replace your SHT30 with A SGP30 and possibly use both at the same time:

• https://www.airgradient.com/open-airgradient/instructions/tvoc-on-airgradient-diy-sensor/
• https://forum.airgradient.com/t/tvoc-on-the-airgradient-diy-sensor/24

[dimmuboy]

Do you know how to make work both SGP30 and SHT30 on AirGradient Pro (PCB v3.3)? When I connect only SGP30 or SHT30 it works well on 3V3 and 5V headers. However when I connect both it doesn't work.
I found this but I don't understand it https://forum.airgradient.com/t/sgp30-not-detected-with-sht30-on-diy-board/197

[handro123]

Sorry my kit did not come with the SGP30 for TVOC so I don't have one to test. There are a few other threads on the AirGradient forums that mention having to remove a resistor or something.

Also mentioned you can reach out and get a replacement / refund for the non-working sensor: https://forum.airgradient.com/t/airgradient-pro-kit-and-i2c-pullups/430/13

I have an SGP41 sensor on order and will try to get it working once it arrives.

[MadMirza]

hi, did you try with the SGP41 sensor
