I have been working for some time to build a completely local simple The Pill by Shelly integration.
The Pill by Shelly integration is execute completely locally (SmartThings Hub is needed) - not requiring additional software running on a different machine (like Raspberry Pi)
Driver is using Websockets communication.
The Pill by Shelly introduction
The Pill by Shelly integration (current prototype) is supporting following Pill’s I/O modes:
Temperature (DS18B20) - Supporting 1 Temperature probe (18B20) + optional 2 x Digital Inputs/Outputs
Digital Input/Output - configurable for up to 3 x Inputs/Outputs
In addition to these, the device supports connecting virtual components (Boolean type)
2 outputs (SmartThings switch) to control The Pill by Shelly virtual components (Boolean type)
3 inputs (SmartThings switch) to read from The Pill by Shelly virtual components (Boolean type)
My intention is to release the driver in August - September if there is interest in using it. For now I will just make this presentation and I hope comments.
Let’s see if there is interest in this kind of integration.
If you are interested, I can share with you the websocket library I used in my Shelly driver. I can’t even remember exactly where I picked it up - the source doesn’t have any attribution. But I was steered to it by a post here back a few years ago. But I remember having to make just a couple tweaks to the code to get it to work.
Of course, I could check out your library. You can DM to me.
I now have the driver ready enough for communication to work in both directions. I’m unlikely to replace the WebSocket library completely.
The driver based on these (hl_websocket.lua & lustre) works well.
The main missing parts are the functions in special situations (connection failure, reconnection, …). Maybe I removed these things when I modified the model driver to use communication with Shellys. Without good comments it is difficult to understand from Lua code what is basic websocket communication and what is manufacturer-specific.
My problem is that I don’t have enough basic knowledge about socket programming.
I would also be interested in the mDNS Lua code for searching for Shellys.
It took a lot of fussing to get come up with a reliable communication link, and one that could reset and restart if errors occurred. I won’t bother you with the websocket library since you already have that. Regarding the discovery, there’s not much to it, once I converted over to the edge mdns library. I’ll DM you that module.
