Leela - The ESPHome Room Multi Sensor for Home Assistant

this is Leela a uh 3D printable multi- sensor housing uh designed to be used with ESP home in home assistant that I've been working on for the last couple of months um it's designed to be modular with uh overtime support for a variety of ESP boards and sensors uh it's launching with support for two boards and two sensors initially uh these are the wios uh D1 mini uh which is very popular and cheap and the tiny uh ESP 32 C3 super mini um sensorwise uh initially it's the HC sr501 P sensor and the BME 280 uh temperature pressure uh and humidity sensor pressure not being particularly useful the version that you see here will be freely available on principal.com on my website uh it comes with uh a simple flat base that lets you set it on a tabletop or shelf um I'll also be selling a tiltable base and wall mount uh that has been the bane of my life for the last two weeks I've designed this in a way that you don't need any mount Hardware like screws to install the ESP boards or the sensors uh so to demonstrate the wios fits into its little carrier Mount by just clipping in the C3 super mini a little bit tighter it's difficult to do when you're trying to film at the same time you go Clips out in and if you want to get these out there's a little ejection tool that fits in the back press he says go and then the sensors again just clip in and the temperature sensor Just Clips in there are optional screws here that you can actually put into Securus as well but um they're not really needed the ESP boards and sensors connect together using female to female depont cables um the only slight niggle uh is that because you have two sensors uh that both have a ground cable uh and the ESP board only has one ground pin um you need to combine the two neutral cables ground cables uh into one connection so I just strip back the shielding from one cable uh and then wrap the um terminal of the other around it and then protect it with um a piece of heat shrink so it's very easy to assemble uh you basically take your um ESP in its Mount clip it into the rear chassis um you then need to connect your cables um which this is a uh this is just a cable I've wired up myself so let's see I have to remember how to do this so first off um there is a passage uh through this Center what I call baffle um this Center baffle basically makes sure that the heat from the ESP weos in this top half um doesn't affect the uh temperature reading um that the the sensor takes down here so they're in two two entirely separate uh areas the the temperature sensor also sits in this little chamber uh as well that has its own own air flow right so let's connect this up P three p and take is these uh you can then pull the cables through a little bit from the bottom and then it basically just slides together like so there's then the base which slops in like this and then there's a locking pin that just slides through the back to secure and that pin can be ejected um by putting a paper clip or something through here and push it it pushes out the pen finally I'll quickly show you the tilting uh stand and War Mount these basically um have a a ball joints at the bottom that is flexible um Let It tilt in different directions and they simply slide in to the bottom like the um standard Mount again locking position with the pin uh that's the tabletop one um the wall mount has a slightly longer Mount so it can rotate all the way to be flat against the wall again slots on secures with a pin any thoughts or comments uh I'll be happy to hear thanks
