The Bright Side<p>Clearing the air: Global emissions of several harmful pollutants are falling — an encouraging trend that suggests we may have passed 'peak air pollution.' Of course, it doesn’t mean it’s peaked everywhere, but overall, it’s good news! <a href="https://mas.to/tags/AirQuality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AirQuality</span></a> <a href="https://mas.to/tags/Environment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Environment</span></a></p>

Pixel is the smallest dragon<p>48 hours of data<br>Day 1: humidifier on the highest setting for around 2 hours before bed in an enclosed room to maintain humidity<br>Day 2: no humidifier in a room with open interior doors</p><p>The goal is still 50% humidity. Humidity is nearly identical overnight at around 40%, though overnight indoor temperature was 72 degrees rather than 66. I don't think I could afford to pay to heat my entire apt just to keep the humidity up, especially when heat and its CO2 isn't what I want. Running a humidifier all night and paying for the water doesn't sound great, but it's potentially more affordable.</p><p>The air quality is also not that much improved. Rather than being slightly above 1000 ppm, it's slightly below, with an extra hour before reaching 900 ppm, though it does stagnate below 1000 ppm overall. Basically, I enough CO2 overnight in a 600 sq ft studio apartment to barely stay below acceptable levels. I probably should open a window if someone else is here. </p><p>Future experiments<br>- humidifier off and the doors closed (to see how much the CO2 increase is caused by being in an enclosed space)<br>- humidifier on it's lowest setting all night (with a kill-a-watt to measure energy consumption)<br>- windows open </p><p><a href="https://post.lurk.org/tags/humidity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>humidity</span></a> <a href="https://post.lurk.org/tags/airGradient" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airGradient</span></a> <a href="https://post.lurk.org/tags/airQuality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airQuality</span></a> <a href="https://post.lurk.org/tags/openSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openSource</span></a> <a href="https://post.lurk.org/tags/openHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openHardware</span></a></p>

Pixel is the smallest dragon<p>- I looked again to see if there is any recent HomeKit integration improvements for AirGradient, but it appears not. They have some old code that has not been modified for newer boards. <a href="https://github.com/gohai/airgradient-homekit#usage" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/gohai/airgradient-h</span><span class="invisible">omekit#usage</span></a> It's not really necessary at this time unless I want a smart plug for the humidifier to turn on automatically. <br>- If I really wanted to. could invest in a device like the Home Assistant Green dedicated to run Home Assistant out of the box, and as well as other services. It's a steep $100 compared to other cheaper boards that can run HA, but would save me some labor. The only board I have is a OrangePi Zero 2w with 1 GB of ram, where HA needs 2 GB.<br><a href="https://www.home-assistant.io/green/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">home-assistant.io/green/</span><span class="invisible"></span></a></p><p><a href="https://post.lurk.org/tags/humidity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>humidity</span></a> <a href="https://post.lurk.org/tags/airGradient" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airGradient</span></a> <a href="https://post.lurk.org/tags/airQuality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airQuality</span></a> <a href="https://post.lurk.org/tags/openSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openSource</span></a> <a href="https://post.lurk.org/tags/openHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openHardware</span></a> <a href="https://post.lurk.org/tags/homeAssistant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>homeAssistant</span></a> <a href="https://post.lurk.org/tags/orangePi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>orangePi</span></a></p>
Pixel is the smallest dragon<p>- I was able to successfully set up the AirGradient alarm, designate AirGradient as a VIP contact, and get banner notifications to my phone and watch when AirQuality has stagnated around 560 or lower to close windows or 900 to open windows. Admittedly, I'm finding that this is a small margin, but there might not be much better ways of improving ventilation as a renter. I will have to accept the humidity losses during the day as inevitable.<br>- I experimented with opening my window in the evening past the lowest outdoor humidity dip to minimize humidity losses, then closed the space and turned my humidifier on for about two hours before bed. The air quality was above 1000 just around 1 am, so I slept in non-ideal conditions for 7 hours.<br>- I learned that I can add notes to my data and hope to do that more often for a few days to better remember when actions can be correlated to changes in data. </p><p><a href="https://post.lurk.org/tags/humidity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>humidity</span></a> <a href="https://post.lurk.org/tags/airGradient" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airGradient</span></a> <a href="https://post.lurk.org/tags/airQuality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airQuality</span></a> <a href="https://post.lurk.org/tags/openSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openSource</span></a> <a href="https://post.lurk.org/tags/openHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openHardware</span></a> <a href="https://post.lurk.org/tags/homeAssistant" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>homeAssistant</span></a> <a href="https://post.lurk.org/tags/orangePi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>orangePi</span></a></p>

Pixel is the smallest dragon<p>- I can use the air gradient alarm system to send me an email when the CO2 has reached "fresh air" levels, after which, it cannot go any lower, and therefore, I should close the window to minimize humidity losses. And vice versa, I can use it to notify me when the CO2 is too high and I should open the windows. <br>- Since I don't usually get notifications for emails in my notification center of my phone, I am going to try to set up air gradient as a VIP contact which should bypass the current notification settings. Then again, I check my email often, so the margin of error from missing an email is potentially small.<br>- I can also play with the timing. I can get them to trigger based on opening/closing/24-hours. I haven't yet adjusted opening/closing hours and am not sure if I can without getting into the code. During the night itself, there are unlikely to be a lot fluctuations and I mute notifications anyway, I think being able to set notifications to certain times of day (morning/afternoon/evening) would be more useful than opening/closing.<br>- I could also use this system to warn me when my humidity is too high. </p><p><a href="https://post.lurk.org/tags/humidity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>humidity</span></a> <a href="https://post.lurk.org/tags/airGradient" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airGradient</span></a> <a href="https://post.lurk.org/tags/airQuality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>airQuality</span></a> <a href="https://post.lurk.org/tags/openSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openSource</span></a> <a href="https://post.lurk.org/tags/openHardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openHardware</span></a></p>
Pixel is the smallest dragon<p>- Currently my strategy is to run the humidifier for a few hours before bed and make sure that the space is enclosed well to contain the humidity. Running the humidifier on the lowest level all night uses a lot of water and raises the humidity beyond 50% which is a mold risk.<br>- Water left in my humidifier when not in use will eventually evaporate ineffectively, I should only put as much water as I plan to use<br>- using the "Humidity Check" app, I found humidity is the lowest outside at 3 pm and the highest around 6 am. The best time to air out my apartment to reduce CO2 while minimizing humidity loss is the early morning and late evening. The exact timing may change with the weather and the seasons. This also means that when my apartment is the hottest during the middle of the day, I risk the most humidity loss if I use fresh air to cool down.

ollibaba<p>Since the US apparently won't share air quality measurements from their worldwide embassies any more (<a href="https://apnews.com/article/us-air-quality-monitors-8270927bbd0f166238243ac9d14bce03" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">apnews.com/article/us-air-qual</span><span class="invisible">ity-monitors-8270927bbd0f166238243ac9d14bce03</span></a>), I'm wondering whether German embassies (or those from other countries) also do such measurements and publish their data.</p><p>Does anyone know more about this?
