+ <p>På onsdag sendte jeg følgende epost til Utdanningsetaten i Oslo
+kommune (UDE). Fikk beskjed om at min henvendelse har saksnummer
+22/7559-1 i den
+<a href="https://www.oslo.kommune.no/etater-foretak-og-ombud/utdanningsetaten/postjournal-utdanningsetaten/">offentlige
+postjournalen til UDE</a>. Jeg er spent på hva slags respons jeg får.
+Mistenker jo de fleste som sprer sine nettsideleseres
+personopplysninger til utlandet ikke har tenkt så nøye igjennom hva de
+gjør, og at det er håp om at de tenker seg litt nøyere om hvis de blir
+klar over problemstillingen. Vet du noen som burde få tilsvarede
+beskjed og spørsmål? Kanskje du kan sende dem en epost. Hvis alle
+bidrar blir det kanskje litt bedre.</p>

+<br>Subject: Digitale utslipp fra osloskolens nettsider</p>
+
+<p>Hei.</p>
+
+<p>Jeg ser at osloskolens nettsider har digitale utslipp av
+personopplysninger til Google, Facebook og andre, blant annet omtalt
+på <URL: <a href="https://aktuelt.osloskolen.no/personvernerklaring-for-osloskolen/informasjonskapsler/">https://aktuelt.osloskolen.no/personvernerklaring-for-osloskolen/informasjonskapsler/</a>
+>.</p>
+
+<p><URL: <a href="https://webbkoll.dataskydd.net/">https://webbkoll.dataskydd.net/</a> > kan være et nyttig verktøy for å holde øye med utslippsomfanget på ulike sider.</p>
+
+<p>Kanskje det er en ide å gjøre noe med det, jamfør <URL: <a href="https://www.digi.no/artikler/debatt-det-enkleste-tiltaket-er-a-skru-av-google-analytics/517378">https://www.digi.no/artikler/debatt-det-enkleste-tiltaket-er-a-skru-av-google-analytics/517378</a> >?</p>
+
+<p>Et alternativ til Google Analytics kan være en lokalt installert
+utgave av <URL:
+<a href="https://matomo.org/">https://matomo.org/</a> >. Den og flere
+andre alternativer kan finnes via
+<URL: <a href="https://www.digi.no/artikler/sverige-vil-skrote-amerikansk-skytjeneste-her-er-alternativene/516223?key=5QsV0wRG">https://www.digi.no/artikler/sverige-vil-skrote-amerikansk-skytjeneste-her-er-alternativene/516223?key=5QsV0wRG</a> >
+på bakgrunn av at svenske myndigheter har innsett at dagens praksis
+nok er både lite lur og ulovlig. Der henger Norge litt etter, men
+osloskolen har her mulighet til å være litt i forkant. :)</p>
+
+<p>Fint om dere kan gi beskjed hvilket saksnummer denne henvendelsen får i
+offentlig postjournal når den er mottatt.</p>
+
+</blockquote>
+
+</p>Flere og flere innser at slik spredning av personopplysninger er
+ugreit. Det har pågått i mange år. Ser jeg blogget
+<a href="https://people.skolelinux.org/pere/blog/Det_er_jo_makta_som_er_mest_s_rbar_ved_massiv_overv_kning_av_Internett.html">første
+gang om Google Analytics i 2013</a> og
+<a href="https://people.skolelinux.org/pere/blog/Snurpenot_overv_kning_av_sensitiv_personinformasjon.html">analyserte
+omfanget i 2015</a>, men det er et langt lerret å bleke.</p>
+
+<p>Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
+det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
+til min adresse

+Merk, betaling med bitcoin er ikke anonymt. :)</p>

+ </div>
+ <div class="date">
+ 12th March 2022
+ </div>
+ <div class="body">
+ <p>Recently I had a look at a
+<a href="https://www.hargassner.at/">Hargassner</a>
+<a href="https://www.hargassner.at/en/products/wood-chip-boiler.html">wood
+chip boiler</a>, and what kind of free software can be used to monitor
+and control it. The boiler can be connected to some cloud service via
+what the producer call an Internet Gateway, which seem to be a
+computer connecting to the boiler and passing the information gathered
+to the cloud. I discovered the boiler controller got an IP address on
+the local network and listen on TCP port 23 to provide status
+information as a text line of numbers. It also provide a HTTP server
+listening on port 80, but I have not yet figured out what it can do
+beside return an error code.</p>
+
+<p>If I am to believe various free software implementations talking to
+such boiler, the interpretation of the line of numbers differ between
+type of boiler and software version on the boiler. By comparing the
+list of numbers on the front panel of the boiler with the numbers
+returned via TCP, I have been able to figure out several of the
+numbers, but there are a lot left to understand. I've located several
+temperature measurements and hours running values, as well as oxygen
+measurements and counters.</p>
+
+I decided to write a simple parser in Python for the values I figured
+out so far, and a simple MQTT injector publishing both the interpreted
+and the unknown values on a MQTT bus to make collecting and graphing
+simpler. The end result is available from the
+<a href="https://gitlab.com/petterreinholdtsen/hargassner2mqtt">hargassner2mqtt
+project page</a> on gitlab. I very much welcome patches extending the
+parser to understand more values, boiler types and software versions.
+I do not really expect very few free software developers got their
+hands on such unit to experiment, but it would be fun if others too find
+this project useful.</p>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
