"you should already have a google account" On October 8, 2025, I sent an email some Members of European Parliament1. This was the first time I’d ever done something like this. The message was addressed to the European Parliament Committee on Industry, Research and Energy. They seemed like the right subset of Members to contact after reading a post on the F-Droid blog: F-Droid and Google’s Developer Registration Decree The post hit a little harder because of an incident a few days prior. I have an Aranet4 Home sensor. This great little device requires an application if I want to access graphs and charts about CO2, temperature, humidity, and pressure (there is a Python client too, but it cannot update the firmware). It works just as advertised, and sometimes I take it to work with me. Unfortunately, starting with version 3.8.1, the application developers added a permission, the _Google Play license check_ (`CHECK_LICENSE`). Prior to this change, when the application did not have this permission, I could use it without any issue. (I’m just guessing that that is the problem, recent versions of the application do not work either.) Why? Because **I do not have a Google account**. As soon as I launch the app, it takes me to the Google Play Store login screen. I emailed Aranet asking for a workaround, because I don’t see why I would need a Google account to use the sensor that I purchased. They said: > 2025-10-06T05:16:34Z ARANET Support support@aranet.com: > > Hello Bobby! > > Did you download the Aranet Home app from the google play store? That is the only place where we officially release the app for android, so you should already have a google account to download from there. > > Best regards, > Aranet technical support I should already have a Google account? _Should I?_ Since f-cking when _should_ I have a Google account? Because I have an Android phone? I replied and stated that there are other safe ways to install applications (like the App Lounge on e/OS or the Aurora Store) and that this exposes more personal data, and it is a disregard for privacy. Because of this somewhat minor change, my Aranet4 Home **isn’t the same device that I purchased**. They altered the agreement. The coincidence of reading about changes to the Android platform after experiencing being locked out of future updates to a device I paid for because I don’t have a Google account made me boil. Not long after sending my email to those members of parliament, Keep Android Open came into being (well, the website did at least). If you’re reading this, you probably know the deal already. As a reminder, though, this bad decision means that in the near future, Android phones will receive an update that will remove your agency to install the applications you want on your device. My edge-case scenario above (which I attribute to poor design) will happen to users for a variety of applications unless Google makes it possible to bypass the verification process. Someone in your circle probably doesn’t know about this coming change, so it is important to share the information with them. Even if they don’t see what the big deal is, raising awareness is important. It could mean that even basic applications, such as a step counter, might share private health information with Google. And applications to control smart devices, like watches and CO2 detectors (he says loudly), would need to connect to Google in order to function (for “reasons”). When you buy something, you should be able to use it without creating accounts and requesting permission from Google. When purchasing a telephone, permission should not be required from a company that had nothing to do with the fabrication of the device to use certain applications. I can break it if I want to. Google is not doing this for safety and security. They are doing it to force control and power on an open ecosystem. It is corporate gatekeeping. **Android needs to remain open.** (And Aranet needs to reply to my email because they ghosted me.) Note: If you are using the Aurora Store and have an Aranet4 Home and you want to be able to continue updating the firmware, you can roll back to the last working version by choosing “Manual Download” from the kebab menu on the Aranet Home page and entering version code `199`. * * * 1. In an act of self-plagiarism, I’ve “woven” bits of the email into this post. ↩

#Aranet PM, CO₂, radon monitored. Windows cracked = radon low. Closed = yikes 😬. Radon pump on hand, not installed. No rush. Heating bill? $75/yr (USDA wood permit). EPA-certified woodstove, dead Uinta NF trees put to use instead of rotting into CH₄ + CO₂.

CO2 monitor reading from about 3PM to 6:30PM It starts off just above 800ppm climbing to above 1000ppm as we are putting on our shoes and crowd around the monitor. It then drops precipitously below 600ppm as we walk to our subway stop. On the subway it climbs all the way to 967ppm. It then drops below 600ppm again as we walk to the cinema. In the lobby of the cinema it shoots back up to 1242ppm. In the theater itself the reading goes back down to 916ppm where it slowly but steadily climbs to 1086ppm. For reference: the ads started at 4PM - 916ppm - the movie started at around 4:20PM - 992ppm - and ended at 6PM - 921ppm. You can see when the ventilation really kicked in because after the peak at 4:48PM - 1086ppm - it quickly and steadily drops down until reaching a low of 868ppm at 5:43ppm. You can then see the drop below 600ppm as we walked back to the subway station, a brief spike as we rode the subway, another dip as we walked home and then the reading inside our apartment.

The seating chart for the theater we were in yesterday. It has 106 seats. The occupancy in this image is not the same as when we went yesterday.

Went to the cinema yesterday. Kept our respirators on. The theater was pretty full (I forgot to take a screenshot of the occupancy yesterday).
Ventilation didn't kick in until CO2 went above 1000ppm.

Rising Outdoor CO2 Levels Harming Life Indoors (Op-Ed) As carbon dioxide (CO2) gains notoriety for its impact on a warming climate — and as levels increase from human processes and natural feedback loops — new data suggest high levels in the air we breath...

‘Carbon dioxide, once regarded as a harmless indoor air pollutant, can seriously impair people’s cognitive ability and decision-making,’ says Harvard researcher Joseph Allen. Learn more in this Live Science feature: www.livescience.com/52619-indoor...

screenshot of the CO2 concentration over the course of one day, according to an Aranet device. The part that is interesting for this post is the bit where the CO2 concentration goes from 552 ppm at 18:17 to 1738 ppm at 19:07; then there is a small dip down to 1243 ppm at 19:17, before it climbs back up to 1807 ppm at 19:27; finally, it drops down to 574 ppm at 19:37.

20 adults in one classroom from 18:30 to 19:30. Someone left half-way through the parent-teacher conference, so that's the little dip in the middle. The air purifier (the height and width of one grown-up, with the depth of a fridge) stood in the back of the room and […]

Wish to see an #Aranet CO2 ppm graph for that any meetings in that building. Well actually in all buildings attended by lots of people.

How many days a year do kids miss out on school due to poor indoor air quality?

Great thread! I love my #Aranet CO2 monitor. @aranethome.bsky.social Always carry it w me. The data it provides helps me determine level of risk/exposure to airborne pathogens, like #COVID, #Measles, etc. Highly recommended! An ounce of prevention is worth a pound of cure. #CleanAir #MaskUp 😷

Oh, looks like a tour group is on here.

screenshot von der Aranet App die einem anzeigt wieviel CO2 in der Umgebungsluft war. Man sieht eine Kurve mit vielen Hochs und Tiefs. Das höchste Hoch geht über 1000ppm und war im Nagelstudio. Danach fällt es abrupt ab und bleibt unter 700ppm im H&M und nach einem Absturz unter 500ppm weil ich draußen war geht die Kurve wieder hoch bleibt aber bei um die 600ppm im C&A. Danach geht sie wieder hoch in die 900er während ich im Supermatkt war.

Heute im H&M und im C&A gewesen. Beide hatten CO2 bei unter 700ppm.
Davor waren wir kurz in einem Nagelstudio und danach im Supermarkt.

Ich habe jetzt mal draußen im Grünen längere Zeit gemessen: Der Wert vom #Aranet schwankt zwischen 395 und 440 ppm. Ich denke, das ist ganz ok. Da muss nicht neu kalibriert werden. Richtig? 🤔

I was wondering why I was falling asleep on the bus but is this good?
