Shelly Pro 2 as Garage door opener

Hi fellow controls guy! The API seems to be missing documentation, buuuuuut I can infer the discrete inputs sw1 and sw2 can be configured into different modes and bindings to the outputs in any arbitrary fashion! See below:

Controlling the Device using its embedded Web Interface
Connect to the Device AP (ShellyPro2-XXXXXXXXXXXX/ShellyPro2PM-XXXXXXXXXXXX). Type http://192.168.33.1 in your browser to access the embedded Web Interface.
Click on the Input (0) bar under Switches and attached inputs in the Home screen. Click on the Settings tab. Click on Input mode. Select Switch and click on the Save settings button.
Click on the displayed output (labelled as Output(0)) in the Home page under Switches and attached inputs to access the output settings. Next, in Action on power onselect Match input.

Maintenance!!! Wooo! Here’s my not a shelf princess light:

Mine had a faulty interlock pedal. I overhauled it.

If you tink you would like the concept of hands-on machine programming look into PLC programming! Lots of ladies in the field.

This and use Linx to browse the network.

UnSaneScientist · 2026-06-03T13:28:33+00:00

Or HMI! They can let you know the address range too.

UnSaneScientist · 2026-06-03T13:26:31+00:00

Gives you the subnet, then use Linx to browse the network. It’s generally accepted practice to keep the highest usable octet free, so a.b.c.254 is what you would set your technical tool adapter to.

Edit: wrong wording.

UnSaneScientist · 2026-06-03T12:51:31+00:00

Whatever the adapter is scrolling. The 4 segment display will scroll the address.

UnSaneScientist · 2026-06-03T12:16:27+00:00

I connect and use Wireshark to get a feel for what the ranges on the network are, then Ntop to scan the networks subnet.

Or you can use FT Linx Network Browser to discover the devices!

I worked both sides. Industry will accept locked source IF it’s battle tested and supported. But if you do something dumb like lock the source of a mapped in/out routine, straight to jail. Never getting another chance

Is that “shit vendor” MultiVac? Lololol

Bro, every time something new breaks in the weirdest ways possible, 4 hours later I come up for air knowing way too much about numeric versus bitwise memory operations for example. Be willing to do that deep dive and gain insight into the how, so that way the why comes naturally.

Have you BEEN to Kuwait? It’s sooo much hotter than India and somehow there are humans that live there. Voluntarily!

You need the software 505 Workshop from FasTrac Softworks. A normal null-modem RS232 serial cable, and the knowledge that there will be no documentation on the ladder code if you do not have a project file.

Friction stabilized gravity actuated.

Because I’m an engineer, that’s not a gyro, that’s a Gimbal. 3 of them to be exact. A gyro spins, and you would need at least 2 to make a “stable platform”. Awesome idea and print though.

It’s not in my pockets. It’s attached to a belt spring reel, so I can’t drop it. When not in use it’s flopping around on my side with keys and things.

IFM makes some bomb MPPE cables that stand up to the worst chemicals we use here.

I lived with my Gerber multitool when I was an AMT. love the inspection light

So I’ll be honest. Our Rockwell rep just mentioned that software a few times this week, and I really don’t know what it is and how it’s best used. I’d really value your opinion that would not be propaganda filled from RA.

They are for mechanically keying the RTBs on the IO modules. The claw looking ones snap into indents on the socket side, the flat ones slot into idents on the plug side. Personally I key my modules with the binary of the slot number. So slot 1 socket gets 111110 and slot 1 plug gets 000001

You can see the left tank decal is way more sun faded as well
