What I’m reading from this and posts from a few others is that they don’t want to feel that you’ve abandoned the earlier hardware. I realize the difference between the chips and that some things aren’t possible with the earlier boards, but something like CO2 Calibration on demand has been present in the Dashboard for quite awhile but it never worked with the promise it is coming soon, and as far as I know, it never made it for the D1 Mini boards.
I also think the Night Mode is a very reasonable request, as I had one night where my HomeAssistant based night mode didn’t kick on and I had to unplug my device as the screen is just too bright in a dark room.
So if I were to make a priority list for firmware improvements for the D1 Mini boards, it would be
- CO2 calibration through Dashboard site
- Night Mode support for turning off the screen
- MQTT if at all possible with the earlier boards so it works with the HomeAssistant Integration, or other desired use cases
Enabling Over-The-Air does take up considerable space, so if that isn’t supported, I think that may be a fair trade-off for still having the features above, understanding that other firmware updates would require opening the case and connecting directly to the D1 board
I think there is reasonable expectation that devices purchased over the last year or two continue to be supported by the company that sells them. You are correct that the older devices are not prevented from working as they were, but things like CO2 calibration never worked and the Dashboard site shows these options to all devices, even if they aren’t supported, which sets the expectation that they should or will work some day.
MQTT is important to the freedom to use our data as we desire, which AirGradient proudly proclaims on the website and comparisons against other air quality monitoring companies.
