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 | Shelly Europe](https://www.shelly.com/products/the-pill-by-shelly)** > > Price: EUR 9.9 > **[The Pill by Shelly - | Shelly USA](https://us.shelly.com/products/the-pill-by-shelly)** > > Price: USD 12.99 > [@Edge Shelly drivers for Gen1 and Gen2 Devices](https://community.smartthings.com/t/edge-shelly-drivers-for-gen1-and-gen2-devices/237544/937#p-1447836-the-pill-by-shelly-1): > > Shelly Gen2/3 Driver Update Notice Name: Shelly Gen2/3 Device Driver V1.7 Version: 2024-04-05T17:29:29.455930569 Changes: Added support for: Shelly Pro Dimmer 2PM Shelly 1 Gen 3 with Temperature Add-on The driver is still on my [test channel](https://bestow-regional.api.smartthings.com/invite/Q1jP7BqnNNlL) and anyone subscribed will get the updated automatically. Thank-you to Clive and Bruno for testing. 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) ![SmartThings Edge Driver Shelly-Pill Device Detail View To ST Community](https://global.discourse-cdn.com/smartthings/original/3X/2/f/2f12e88e1a2018bc65a7ea77e3c111a4c1b0d5b4.png) ![SmartThings Edge Driver Shelly-Pill Device Settings To ST Community](https://global.discourse-cdn.com/smartthings/original/3X/1/a/1a4b1e0f4c9debc650b796a0d948fc4de9943dd3.jpeg) The Pill by Shelly Configuration IO ![SmartThings Edge Driver Shelly-Pill Configuration IO To ST Community](https://global.discourse-cdn.com/smartthings/original/3X/a/f/af3908019a1766db74740d102b219fb7efd4f79a.jpeg) The Pill by Shelly Virtual Component example ![SmartThings Edge Driver Shelly-Pill Virtual Components To ST Community](https://global.discourse-cdn.com/smartthings/original/3X/7/1/71c8dbabbe35718e39efd7e30518f026b6c23894.jpeg) _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. ---

@TAustin mentioned somewhere that Shelly Gen3 supports Websocket communication. This Shelly WebSocket driver uses this driver as a model: > **[SmartThingsEdgeDrivers/drivers/SmartThings/harman-luxury at beta ·...](https://github.com/SmartThingsCommunity/SmartThingsEdgeDrivers/tree/beta/drivers/SmartThings/harman-luxury)** > > beta/drivers/SmartThings/harman-luxury The selection criteria was that this implementation seemed the simplest of all.

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. ---

> [@TAustin](#): > > If you are interested, I can share with you the websocket library I used in my Shelly driver. 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. > [@TapioX](#): > > [SmartThingsEdgeDrivers/drivers/SmartThings/harman-luxury at beta · SmartThingsCommunity/SmartThingsEdgeDrivers · GitHub](https://github.com/SmartThingsCommunity/SmartThingsEdgeDrivers/tree/beta/drivers/SmartThings/harman-luxury) 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. ---

I have been testing the driver for over two months now. If there is interest, I can release driver (test channel’s invite link) to alpha tester(s). ---

That’d be awesome! My pill arrived today n I’d like to add it to my smartthings
