I bought one of the DIY Pro kits and put it together. I liked it overall. I think the kit is a good value, it's convenient to get everything all together, and the injection molded case is nice. The included software and cloud dashboard are convenient and functional. There are some less good parts, though:
- The instructions aren't great, but I can't remember what I had trouble with specifically.
- The included screws for the case are tiny, soft, and aren't self tapping. I never got them in all the way and gave up on them after the first disassembly. The USB power cable sort-of holds the clamshell together without them.
- I had issues with the reliability of the connection to the I2C sensors, especially after adding the SGP30. Reducing the speed to 100kHz helped somewhat but made the display update slowly. I never got the SHT3x temperature sensor to work reliably in the bottom corner position, so I moved it to the open top spot. I did try out various levels of I2C pull-up and removed redundant pull-ups from the modules that came with them installed. I think part of the problem is the loose fit of the included pin headers, soldering the sensors directly may help.
- The temperature sensor always reads high by about 5-10 degrees F, even when installed in the recommended far corner position. I tried mounting the airgradient vertically to try to induce a draft to clear out the generated heat but that didn't help. I could try to calibrate it but I doubt it's a simple offset.
- The dashboard is basic, had some annoying bugs, and they want you to pay for it. I can't remember specifically what I disliked because I replaced the firmware with EspHome long ago and set up a grafana dashboard to monitor it.
- ahaucnx 4y agoThank you for your feedback. With the new version (3.7) that is also now sold as the updated kit we have addressed most of these issues. - we now supply stainless steel torx screws including screw driver - we have now the SGP41 AirGradient module in our shop that has no pull up resistors and works very stable - we redesigned the i2c circuit which now runs completely on 3.3v - so far we never charged a DIYer for our dashboard but might do so at a reasonable price in future if our server costs rise. We continue fixing issues (software and hardware) that come up in our forum and are dedicated to ensure we deliver a high quality kit.
- runjake 4y agoI just got my DIY Pro Kit a couple days ago and put it together and got it online today. Some issues: - It’s easy overall but the instructions are pretty not good. - The OLED displays text upside down. As far as I can tell, it is mounted the only correct way it can be mounted in the case. - The unit is connected to Wi-Fi and is pingable, but it’s only communicated to the dashboard once. It’s displaying data on the OLED. I don’t have any firewall rules for it. Definitely more troubleshooting required on my end. I’m using a 1A power supply for it. Does it need more?
- ahaucnx 4y agoPlease give feedback on the instructions so that we can improve them. You can also message us through the support form. If the text is upside down, you flashed from the wrong build instructions. For the PRO Kit (OLED bottom right) use [1] for PRO Presoldered (OLED top left) use [2] The reason we had the display on two different location can be found here [3]. From now onwards we will only have display windows on the bottom right. Please use at least 2.4A power supply. The WiFi issues could be due to that.

- runjake 4y agoAm I confused? I have the pre-soldered kit, but the OLED display is on the bottom-right, not the upper-left. https://imgur.com/a/CkPv7FD https://imgur.com/a/CkPv7FD I will try to track down a 2.4A power supply, thanks.
- ahaucnx 4y agoYou might have already gotten the new kit. Can you please contact us at https://www.airgradient.com/support/ https://www.airgradient.com/support/ and let us know your order number. It should be easy to fix.
