In ESPHome I’ve managed to successfully setup a D1 Mini to open/shut my venetian blinds using the cover integration. So the software side of things is fine. I now need to get the physical side of things working. Please find below pictures of the:
Originally, I naively thought I could connect the servo screw/cog to the coupler but even if I found a way to drill the hole bigger, unless it is wedged like the servo cog, it wouldn’t connect properly anyway. I have done a bunch of googling and can’t find any couplers that would connect to the venetian blind hook and am out of ideas re. how to connect all the bits together. Any suggestions welcome!
If you have access to a 3D printer, you could try this window blind mount. I did have to design and print a custom coupler to fit over the blind hook to fit my blinds.
Hi @MartinB, many thanks for that! As you say, I’d also need to create a new coupler to fit both my servo screw and the blind hook. Any tips on where I can look for some 3D templates for that kind of thing? (I’m a real n00b when it comes to 3D printing).
I bit the bullet and learned to use Fusion 360, which has a free option. I watched some YouTube videos and after a bit of a steep learning curve I can now design and print what I need!
I had a 3d printed shaft mount for servos. This requires you to mount the servo directly to the actuator rod and remove the external control mechanism. The servo sits perfectly on the channel and lines up to the rod if you snip off one of the servo mount points.
This is an older picture, but that is the printed mount sitting in the tray. I no longer have this setup as I just built a new house back in October. Unfortunately no automated blinds were needed. Don’t worry the house is fully automated, just no blinds.
My NodeMCU board got fried somehow and so I replaced it with a spare D1 mini I had. I now want to attach an LDR sensor but the D1 mini only has one ground pin. Is there a way of achieving this (without buying another NodeMCU)? Thanks for the suggestions.
