#ds18b20 — Public Fediverse posts

🌡️ Thermoservice v0.8.0 released!

Temperature sharing service for DS18B20 sensors — now with Home Assistant integration.

✨ New in v0.8.0:
• Home Assistant push integration (thermoservice-homeassistant package)
• Systemd timer pushing temperature every 60s
• Modern HA rest: sensor config with unique_id
• Ansible deployment playbook for automated setup
• Temperature precision fix (4 decimal places)

📦 .deb packages attached to the release.

J'ai une #idee ! (oui : encore)
J'ai une raspi5 qui fait home cinema
mais je manque de retours de température dans la maison 🤔
Alors j'ai des #DS18B20 #1wire, et la raspi a des #gpio
Bon jusque-là : ok
Mais la raspi chauffe, et des fils + un truc format transistor qui traîne (oui : encore), bein c'est moche, et ça va mesurer le dégagement de la raspi.
Alors je me suis dit :
il faut le surélever, et trouver un design sympa.
Conclusion : une main qui lève le doigt en #3D avec le capteur logé au bout du doigt.
Et en cas de question :
"Mais c'est quoi ce truc !?"
- c'est un thermomètre : c'est pour mesurer la température au doigt mouillé" 🤭 😂

So I stuck three #ds18b20 temperature sensors in our boiler. An #esp8266 and #esphome made them usable in #HomeAssisstant. What I couldn't have guessed is how much heat is transferred via the wire. When just stuck in a drilled hole through the insulation the temperature was 50⁰C. I then dug out the insulation and taped the sensor and some wire directly on the steel and foamed the cavity shut, the actual temperature is 73⁰C!

My smallscale reliability test for the good old watertight #DS18B20 temperature probes. I am comparing 4 different ones. All are being plotted into #InfluxDB. Let's see which survive and which are outliers. I'll report back in a week or so.

Делаем автомобильный компьютер с нескучным функционалом

Привет, я собрал небольшой бортовой компьютер для авто, который умеет показывать температуру, время с момента включения и раздавать «Free Wi-Fi». В этой статье приведён код, список компонентов и всё остальное, чтобы собрать такой же. Назвал я его Kruk — от беларуского слова «Крук» (рус. «Крюк»). Вот видео его работы на YouTube . Здесь его страница на GitHub. Если вы уже посмотрели видео, то понимаете суть функции «Free Wi-Fi». Как только к Wi-Fi подключаются, система сразу переводит пользователя на captive portal , а сам компьютер начинает показывать, помимо температуры и времени, ещё два дополнительных окна с информацией о количестве пользователей, подключившихся к Wi-Fi, и о количестве пользователей, которые до сих пор к нему подключены (online).
