Hello,
I have an old PCS10 that I have been using for many years. Realize that if I manage to connect this to a humidity and temperature probe I can log the values from the attic of my house. Anyone that has done this earlier?
Found one possible measurment part like this:
Velleman VMA311 Digital Temperature Humidity Sensor
Will this work, or anyone have a better sugestion.

Hello @uabtorw ,
It’s not possible to connect VMA311 (DHT11) sensor to the PCS10 directly.
Because this sensor has his own single wire protocol for transferring the data.
This protocol requires precise timing. Via the DHT11 library and an Arduino controller board you can readout the sensor on a simply way.
To log the sensor(s) in your home, you can use an ESP32: WPB109 or ESP2666: WPB107 board
and add this to Home assistent via ESPHOME.
