Waveshare Industrial 6-Channel ESP32-S3 WiFi Relay Module, Supports WiFi/Bluetooth/RS485 Control, Onboard RS485 / Pico HAT Interfaces, with Multiple Isolation Protection Circuits

Great controller with ESP32. Easy to program with Arduino IDE. Lots of over voltage protection.

This thing worked beautifully! I used it to replace my sprinkler controller and run off Home Assistant and it has been flawless!

I have had my share of problems with Waveshare products in the past. This product is not one of those, it's whole other animal. Physically, this thing is built like a tank, has solid documentation and is well designed. Most of all, it just works. whether I programmed it with ESPHome Aurdino or MicroPython. This thing is just easy. It has become my goto platform for prototyping for any ESP32 project.

I lovw this so much, I bought a second

This is a copy of the review I did for the ESP32-S3-Relay-6CH which I bought when I returned this 8CH unit because i was having issues and purchased a 6Ch version which had same bug. read on: 1) Out of the box the -STA demo failed to have a clean compile. Had to fix bug in Waveshare's function Bluetooth_SendData(); not good! I think this was because my system had newer IDE libraries. Update dthe code with a fix and got a clean compile. After that, and after loading the -STA demo in a few times, the ESP32 would crash and do a register dump. This was because I commented out the Bluetooth_Init() in setup(). Unfortunately, the Waveshare Bluetooth_sendData() function fails to check for a null pointer and the system crashes (note the pointer was NULL because I commented out out the Bluetooth_Init() function in Setup() ) (good coding requires checks for null pointers). 2) The demo app for -STA works...after THREE DAYS wasted fixing issue. Can turn relays on and off wirelessly from a web page. Enter the IP of the relay board into the URL of the browser to bring up the webpage. 3) The Arduino IDE takes wayyyy too long to cycle through the build-load-run to be useable in a professional (paid employee) iterative software development environment. Under Arduino IDE, WAY too slow with this ESP32-S3 (ESP32s in general). 4) Now, today, I am at the point where I have a working Waveshare device, but am exhausted form the PROBLEMS. Will take a break and come back to this in a few days after I get some real work done on the actual project I bought the device for. 5) Tested WiFi w/Asus RT-AX3000 router indoors and Waveshare device outside 200ft from house. AOK! SUMMARY: Excellent quality electronics, but with a bit of caution when developing the software. FOUR STARS. FIVE if the demo had worked out of the box!

I use one of these boards in an automation project utilizing ESPHOME and Home Assistant. It works amazingly well. Simple to setup with flexible power options. I have had several power surges and outages since putting this into production full time and it has continued to work with no issues. I have not tried the RS485 interface and power it with a 12V switching power supply.

Looks like it will do what I need. I haven't had time to put it to use, yet.

My rating is extremely ... estimated at this point, based on other reviews, and the gadget in front of me, and my technical background. From five points, I'm taking one point off for the effort of finding the documentation. And now, I can save some time for others similarly situated: (1) THE SITE YOU WANT is that of the designers: waveshare dot com. (2) FIND THE PAGE FOR THIS PRODUCT and there, (3) FIND THE LINK TO THE WIKI. Looking that material over is a great idea, whether or not you've already purchased this gadget. The reading will give you a feel for whether you're in the right branch of the technical family to enjoy the board-bring-up process. Me, I do expect I'll enjoy it. It's my first ESP32, but I'm an electrical engineer, I "get" embedded programming, and I'm familiar with the Arduino IDE. The extreme flexibility of this device and, relatedly, the demo procedure/tutorial approach of its online documentation, places it comfortably in the "Maker" branch of the family. That cohort and mine aren't always into the same stuff, but close enough that we could sort of drink in the same bars without brawling. Your mileage may vary.

Läuft bei mir mit Tasmota als Heizungs/Mischerregelung mit 5 Sensoren(DS18B20), Mischer + FBH Pumpe. Das ganze kombiniert mit Display(ILI9431) und MQTT. Andere hätten für solch ein System 300-400€ verlangt.

Fungerade direkt och det var inga problem att få igång den med ESP-Home

Complete esp home config for this can be found on waveshare documentation website. There is a lot of documentation available. Works very well, and I am using it do drive motors, lights and shades in my garden.

Tolle Qualität. Verwende ich auch industriell, ist ein gutes und robustes Design!

Bin von der Qualität des Waveshare 6-Channel ESP32-S3 WiFi Relay Modules überzeugt und gebe hier gerne die 5 Sterne. Bereits optisch sieht es qualitativ hochwertig aus und funktionierte bei mir dank der Doku des Herstellers auf Anhieb. Waveshare verlinkt dabei auf eine Wiki-Seite mit unterschiedlichen Nutzungsmöglichkeiten. Falls notwendig bestelle ich das gerne wieder.
