I have been looking at MotionEye as well, but haven't yet had the time to start on it. I'm hoping to make a rpi powered hub for a pair of cameras on my horse trailer that I can access and stream to the computer I'm building for my 2005 Dodge truck via wifi. I'm sure it can be done, but I'm concerned about lag time. A trailer backup camera with high lag just won't do. Right now I'm concentrating on just getting OAP up and running to it's full capability, then I'll start on the trailer computer.
I have decided that maybe others who have indicated the rpi's Broadcom bluetooth chip just isn't up to the task of hands-free calling may be right. I'm going to go ahead and order a Panda bluetooth dongle and see if that cures the ills I'm having.
Sure would be nice if somebody could get a TPMS application working for OAP! I'd love to be able to monitor the ten tires on my rig as I'm driving down the highway!
Check out the Everlanders videos for your camera set up. This is what I am working on, but aiming for the wireless set up like you are talking about (I'm certain the wife will want cameras in her horse trailer, too... she already wants them in the barn for foal watch season). His videos are here: Part 1 and Part 2.
For your TPMS, it should be doable if you add Ardiuno into the mix. Check out Automate Everything's videos to help along with that. He focuses on pulling the given resistance (Ohms) from individual button presses, obtains the readings with Ardiuno, and monitors those readings with the RPi via GPIO pins. Between what he does with the steering wheel controls and what he and Everlanders do with the camera scripts, you should be about 75% of the way there for your tire pressure monitoring... Part 1 and Part 2 (He started with Crankshaft, but switched to OpenAuto Pro later due to better customer service).
Ultimately, I believe your TPMS is going to either be resistancy readings (Ohms) or frequency readings (Hz). Eitherway, there is an Ardiuno project to gather the data. Pay attention to where Automate Everything screwed up in gathering accurate data to use... he admits it and discusses it in the second video.
They both discuss using a USB sound card or a HAT for mic in and audio out. I, too, am looking to relocate my factory stereo to use as the audio amplifier and maintain the ability to easily return my car to stock if needed instead of hacking up a bunch of wires.
