It would be great if someone would pick up a project like ESPhome.
Then you could choose what type of sensor you connect to your sensor sender.
ESP32 or equivalent would be a great sender. Could be implemented as Bluetooth or WiFi.
Maybe some way in NodeRed?
EDIT:
So, got a little bit in to the topic:
I’ve got now an ESP sending data to my Cerbo. Can read it in Node-RED.
Question now is: How to get it displayed as a temperature on the Venus Screen?
