DS18B20 data from Rasberry Pi use in Homey flows

kooskortekaas

I want to use the temperature of the waterpipe for switch the ventilation in the bathroom. 

I installed the DS18B20 temperature sensor with the Raspberry pi. Now i want to use the temperatuur data to use it as trigger in my flows for Homey. For example, when the temperatuur is above xx-degrees or when temperatuur is increasing then the ventilation starts.

I think i have to use the http requests, but i can’t find a right solution for it. Who can give me some hints to resolve this?

Id o have the same question.
I learned already you can use the MSQTT app. I only didn't figure out yet how to use it with the RPI

Is your goal to switch on the ventilation when it's humid or do you just want to build something with the temperature sensor and the pi, just because you can?

If it's the first I'd just order this one: https://www.gearbest.com/access-control/pp_626702.html and use it's humidity sensor in a flow to switch the ventilation.

Thanks @DaneeDeKruyff. Indeed it's just because i can, maybe i want to do more with this temperature sensors.

JPe

See the description of https://apps.athom.com/app/com.internet  where you can find a lot of details how to use it
For MQTT see  https://apps.athom.com/search?query=mqtt

@JPe I read it now three times, but i don't know how to start te http request from the DS18B20 on the Rapsberry.

Python pushes the temperature every second. I think i can use this in my Homey flows with HTTP Request? Who can give me some info how to start with this? After a week of searching, reading and trying, i think i can’t do it by myself.....

Why not use a ESP8266 chip with Homeyduino app, works like a charm and is cheap.
