Subject: [PATCH] docs: clarify DPS310 availability on AIR-1, MTR-1, MSR-2
(#896)
A small subset of these devices shipped without the DPS310 sensor
because the part was discontinued by the manufacturer. Customers seeing
the DPS310 entities reporting "unknown" in Home Assistant have been
confused, so this expands and aligns the existing availability notes.
Changes:
- Add a new FAQ entry on each of AIR-1, MTR-1, MSR-2 that directly
addresses "DPS310 shows unknown - is my device broken?"
- Add the availability note to MTR-1's DPS310 Temperature Offset and
MSR-2's DPS Temperature Offset config entries (was missing; AIR-1
already had it on its Pressure Offset).
- Add a DPS310 Pressure sensor entry to AIR-1 sensor-definitions
(firmware exposes it but the wiki didn't document it).
- Convert the Homey AIR-1 and Homey MSR-2 sensor-definitions pages
from stale full duplicates to --8<-- snippet wrappers of the main
files, matching the MTR-1 Homey pattern. This also picks up the
DPS310 availability notes on the Homey side automatically and fixes
a wrong "psi" unit on the stale Homey AIR-1 copy.

* The AIR-1 uses a high-quality SEN55 sensor with a 10-year lifespan, designed for continuous use. Its readings are highly accurate for particulate matter, VOC Index, and NOx Index. However, keep in mind that the ESP32-C3 generates some heat, which may require you to apply a temperature and humidity offset.
-12\. **How can I use the RGB LED for notifications?**
+12\. **My DPS310 Pressure or DPS310 Temperature shows as "unknown" in Home Assistant. Is something wrong?**
+
+* No, your device is fine. A small subset of units shipped without the DPS310 sensor because the part was discontinued by the manufacturer. If you see those entities reporting "unknown," your unit is one of these. Every other sensor on the device works normally.
+
+13\. **How can I use the RGB LED for notifications?**
* The RGB LED on the AIR-1 can be customized to show different colors for different events. For example, you can set it to flash red when air quality is poor, green on trash night, or blue when CO2 levels are safe. You can configure these notifications through Home Assistant.
-13\. **How do I update the firmware on the AIR-1?**
+14\. **How do I update the firmware on the AIR-1?**

-15\. **Does the AIR-1 work outdoors?**
+16\. **Does the AIR-1 work outdoors?**
* The AIR-1 is primarily designed for indoor use. It could be used outdoors in a sheltered environment, but it is not weatherproof. If you need outdoor air quality monitoring, ensure the device is protected from the elements.
-16\. **What is the power source for the AIR-1?**
+17\. **What is the power source for the AIR-1?**
* The AIR-1 is powered via a USB-C connection. It can be plugged into any standard wall outlet using a 5V adapter.

+18\. **My AIR-1 CO2 sensors are having a sawtooth pattern, is there any explanation?**
* Some users have noticed the AIR-1 with the "Apollo" side facing up will produce strange behavior with the CO2 sensor readings fluctuating way more than they should. Simply turning the AIR-1 to the other side makes this problem go away!
-18\. **Can I integrate multiple AIR-1 sensors in my smart home?**
+19\. **Can I integrate multiple AIR-1 sensors in my smart home?**
* Yes, you can have multiple AIR-1 sensors in your Home Assistant setup. Each sensor will be recognized as a separate entity, allowing you to monitor air quality across different rooms or spaces simultaneously.
-19\. **How customizable is the AIR-1?**
+20\. **How customizable is the AIR-1?**
* The AIR-1 is fully customizable via ESPHome. You can adjust sensor settings, create automations, modify reporting intervals, and even customize the RGB LEDs. Additionally, we provide open-source CAD drawings and code for further customization.
-20\. **How frequently does the AIR-1 report data?**
+21\. **How frequently does the AIR-1 report data?**
* The reporting frequency for each sensor is adjustable via ESPHome but most default to 60 seconds. You can choose to have data reported as frequently as every second, or adjust intervals to save power and reduce data traffic.
-21\. **Does the AIR-1 require specific software?**
+22\. **Does the AIR-1 require specific software?**
* The AIR-1 is designed to work seamlessly with Home Assistant through ESPHome. All configuration, monitoring, and automation setups are done through these platforms.
-22\. **Is the AIR-1 compatible with other smart home platforms?**
+23\. **Is the AIR-1 compatible with other smart home platforms?**
* While the AIR-1 is optimized for Home Assistant and ESPHome, you may be able to integrate it into other smart home platforms using custom configurations or MQTT, but Home Assistant remains the primary platform.
-23\. **What's the difference between the AIR-1 and other air quality sensors?**
+24\. **What's the difference between the AIR-1 and other air quality sensors?**
* The AIR-1 is unique because it offers local control with no cloud or subscription required. It also provides a wide range of sensor data (PM, VOC, NOx, CO2, temperature, humidity) in a compact, affordable package. The addition of the RGB LEDs and open-source nature makes it highly customizable.
-24\. **What are the optional add-ons for the AIR-1?**
+25\. **What are the optional add-ons for the AIR-1?**

-29\. **How long does it take to set up the AIR-1?**
+30\. **How long does it take to set up the AIR-1?**
* Setup typically takes around 5-10 minutes. Once powered and connected to WiFi, it can be configured quickly through ESPHome and Home Assistant.
-30\. **How secure is the AIR-1?**
+31\. **How secure is the AIR-1?**
* The AIR-1 operates entirely on your local network and does not send data to the cloud. All information is processed and stored locally, ensuring the security and privacy of your home automation setup.
