First of all sorry for the late reply. I somehow missed it.
No, unless they somehow register to the system via the normal sensor APIs, but I am not aware that this is somehow possible (with the exception of USB microphones). The problem is that such devices do not follow a standard that we could implement, so it requires a per device solution. Do you have a specific sensor in mind? I would be interested to have a look at it.
Sorry, I do not fully understand the question. If you want to transfer sensor data from an ESP to phyphox, it is as simple as adding three lines of code in the Arduino IDE using our phyphoxBLE library. If you have an ESP32 at hand, you can give it a quick try by installing phyphoxBle from the Arduino IDE's library manager and then try this example: https://github.com/phyphox/phyphox-ardui...umbers.ino
It transfers random numbers to phyphox as a stand in for a real sensor, but of course this could be any data from any sensor that you are able to read on the ESP32. The other examples show how to set up the user interface, transfer multiple values, change options for the graphs etc.
(If you are not using the Arduino IDE, but VSCode, it should still be rather simple. If you are not using the Arduino platform at all for your ESP, then you will have to implement the BLE communication yourself, which is still possible, but a lot more complicated.)
No, phyphox is build as an "activity", i.e. it is stopped by the system as soon as it is not active in the foreground. However, we have an option to use the proximity sensor to turn off and lock the screen (like the phone turns off the screen when you are on a call and holding it to your ear). On the main screen tap the "i" at the top and then select "Settings". There you will find the option for the "Proximity lock". Then the screen will turn off while the phone is in your pocket or if you put something close to the proximity sensor (typically at the top of the screen) while phyphox can still continue to measure.
