- A WiFi thermostat costs 150 bucks, a sprinkler controller is $250.
- A Siemens industrial programmable logic controller (PLC)is $300 without WiFi!
Why such a rip? It's proprietary software...costs a lot and never does exactly what you want.
Sorry, corporate.... The IoT is OPEN SOURCE. Look how easy it is to code:
Do it yourself. Do it quickly and easily. This reliable PLC is more than enough for real HVAC work, home theater control, a sprinkler controller, email notification, alarm systems, a pet feeder... You name it!
For simple applications, you don't need to code at all! The demo code gives you control from any web browser, so you can wire it directly to a light switch, garage door opener, etc. Just add two wires from the PLC to each circuit. Log in from your cell phone or network and you're in control with NO PROGRAMMING AT ALL!
This project is a full PLC, not just a development board. That means the relays,drivers, input protection circuits, power supply,etc. are all integrated on ONE board. Connect directly to the PLC. No "shields" are required.
There are are four digital inputs and 4 relay outputs. There's an analog-input for measuring things like temperature or soil moisture. It's built with quality parts on one high-quality board -- not a stack of imported PCBs. It's professionally designed and built in Silicon Valley, U.S.A.
Have a peek inside:
It's really, truly, honestly open source. There's a super-clean IDE. For Lua, check out the NODEMCU project. Or, if you prefer C, use Arduino. There's a ton of free code on the web. Just copy and paste the modules. We've worked out all the hardware quirks. You just plug it in and run.
Risks and challenges
Our last campaign shipped in 5 days. Check the feedback.
After supporting an overpriced & delayed Arduino PLC, we decided to do-it-right. We put 4 months of blood, sweat & cash into the design. We worked after-hours in a Silicon Valley lab to eliminate every bug. 11 prototypes were built & checked. The new gold-plated production PCBs are now ready. We'll use your pledge to offset the cost of components. There's virtually no risk.
We've limited the reward quantities to get them built, tested and shipped via Fed-Ex ground on-time to any continental US address. We'll build extras for walk-in supporters. If you're in town, plese stop on in and pay us a visit at 2695 Walsh Ave. Santa Clara.

FF and Sergey P crafted the demo code. TeamIoT designed the hardware. And let's thank these guys for their help: The Arduino IDE comes from the Arduino team under GPL. The ESP8266 core includes the GPL xtensa gcc toolchain. Esptool was crafted by Christian Klippel and licensed under GPLv2. It's maintained by Ivan Grokhotkov. Espressif SDK is under Espressif MIT License. ESP8266 core files are licensed under LGPL. SPI Flash File System (SPIFFS) used by the PLC is written by Peter Andersson under MIT license. The wonderful ESPLORER IDE is from our friend 4ref0nt. And most important...Thank YOU for your pledge.Learn about accountability on Kickstarter
