What's Changed
- Finally using correct units for Formaldehyde by @dotvezz in #40
- Use HCHO as the Formaldehyde sensor entity name by @dotvezz in #41
Special thanks
Thanks to @Anto79-ops for spending so much time helping investigate the HCHO sensors in the devices. His contribution to the effort was beyond significant, and this fix would have been impossible without his patience and diligence. #4 partially documents the insanity we both fell into while trying to figure this out, and it will be my honor to finally mark that issue closed.
A note on the sensor entity name:
If you have any existing Formaldehyde devices, you will notice that this release creates a new sensor entity named "HCHO". There are a few reasons for this:
- For your convenience: your old "Formaldehyde" sensor entity has been collecting data with no recorded unit until now, and conversion to the new mg/m3 unit is impossible.. If we kept it on the same sensor entity, it will cause issues in Home Assistant which would require manual correction on your part.
- To be consistent with Dyson's documentation, Dyson's Mobile App, and your device itself. All of these display "HCHO" as the sensor label, including the LCD screen built into the device itself.
You may choose to keep the dead Formaldehyde sensor entity, or you may also choose to remove it by visiting https://my.home-assistant.io/redirect/developer_statistics/ and searching for "formaldehyde"
