CYD ESP32-3248S035C T&H Sensor (I²C / SHT40) integration?

[RaW79]

Hello

I´m using a CYD ESP32-3248S035C with openHasp for Touch control of my Air condition.

Now I also like to have an additional temperature information from this position to be send by mqtt. I realized that the CYD has a dedicted connector for this (GND, IO22,IO21,3.3V):

But because I´m not so experienced I could not find out how to implement/use with openHasp such additional sensors.

Because I like the accuracy and also have it in place. Is it possible to connect by I²C such a SHT40 sensor?

In the GPIO configuration menu of openHASP I could not identify how to do this. Can you please give a hint for the right information to read into this?

Do I have to integrate sth like this? https://github.com/libdriver/sht4x

Thanks and I´m not using HomeAssistant, so have to send the read out temperature and humidity directly from ESP to mqtt.

Thanks

Adding custom sensors to openHASP requires you to compile your own firmware and add custom code and drivers to the project.

Thanks. Is there any temperature sensor which works out of the box? Might be easier for me to buy one of these types if applicable (v0.7.0rc12)

There is no support for temperature sensors out of the box. openHASP focuses on the display of objects on the screen. There are lot of projects that you can use to build all kind of sensors.

Thanks, but no project is supporting the CYD like openHASP. Tried already HASPmota but endet in a nightmare for me and was happy to get openHASP going.

So will be a tough one for me.

So started to learn compliling by this manual and the developement branch seems to be newer (0.7.0.1) than officical release for this CYD (0.7.0RC12).

Hopefully I checked/uncommented all necessary things for ESP32-3248S035C.
I just used "user_setups/esp32/*.ini" & "esp32-3248s035c_4MB"

Hope now to have a comparable official release and have to find out how to integrate sensors.
Guess it would be most comfortable to use known examples (like popular DS18B20) but I´m at the very beginning what and how to do.

There are several options and which one is best suited for your use-case depends on your requirements, skill and time:

• Compile openHASP firmware to include custom code and driver to support the sensor
• Use a different project that supports the CYD device and the sensor out of the box
• Connect the sensors to another ESP that talks with openHASP using mqtt
• ...
