I am after a device that will give me the angle of a surface, I have built a drop down flap from my suspended ceiling, it is operated by an actuator that is trigger up or down from a broadlink RF pro. I want to know what angle the door is at, so 0 degrees would probably horizontal, 90 would be open fully.
Thank you, I have just started getting into ESP, got a few Bluetooth repeaters and Bluetooth presence sensors, do yo have any links that would get me started to building something like this?
Well, it is as easy as to use a esp of choice (like a $2 d1 mini clone for example) and connect it to a magnetometer of choice (looks like they are all I2C based) with two wires for the I2C communication and two more for voltage/ground for the sensor 
Could also go for the more expensive boards with STEMMA QT / Qwiic connectors so it’s more a plug’n’play solution
Thank you very much, I will have a play.

If any troubles occur there is a very active esphome category in this forum 
And the getting started guide from esphome is quite useful if you just get started 
Excellent thank you
Maybe an approach could be using a BLE beacon with an accelerometer. This would not require soldering and will give you the position change.
More info below:

A BLE gateway can be used to retrieve the information from the beacon and translate it into a position.
