Only a few sensors, readable via the internet? DIY?

Smart home, home automation - is not a topic for the house to be built. However, the house will not be continuously inhabited in the first few years, and the idea came up that it might be interesting to be able to query some data anytime via the internet: temperature and humidity. Out of curiosity and to possibly send someone to ventilate.

So something very simple. Maybe even DIY, the common complete systems seem overdimensioned to me.

After days of research, I’m at a point where I have read about many components but lack the overall connection.

There will be the Fritzbox in the house and next to it a NAS (Synology). One of the usual systems could run on the latter: FHEM, Open HAB or io.dingens. Access to the data from outside could run through that.

Then I read about Arduinos and/or DHT22 sensors that could measure temperature and humidity for me.

How do the measured values get to the NAS? What else is needed in between?

Network cable? Keyword PoE - could the sensor be operated without its own power supply? (ok, question for the Arduino forum)

Does all this somehow fit together? Or won’t I get anywhere this way and do I need something completely different?

Regards, Jens

1,2,3 NEST thermostats (or other comparable ones) and everything you describe would be solved. Without great knowledge and quite fail-safe.

You can also manage it via Netatmo as a non-permanently installed system for little money.

Or Homematic. The Raspi-CCU + wireless wall thermostats (temperature + humidity) in the desired rooms.
