gssmahadevan Hi Vinnie, Thanks for your excellant feedback. Do the boards have an option to burn custom FW. Is the WiFi chip is of esp8266/esp32? Can you send some information (like circuit board diagram,chip info, any pins available for custom FW). I need to use custom FW as i don't want internet-server based control. Thanks

I'm a software developer, have built my own Amazon Alexa remote relay unit. I bought the relays, power supply, power conversion, Node MCU (ESP 8266) WiFi boards, wrote all the software to be discovered and react to voice commands. But now I buy these Sonoff relay devices. They are designed very nicely, and the software is very good. Mine supports Captive Portal, local website, and works from voice commands from Amazon Alexa, and although I could reflash it, I see no reason to do that. The Sonoff code is very good and extensible. I had it working flawlessly on my Amazon Alexa and Google Home in minutes. Great product, easy to configure ! Only negative, is the power input is held via friction inputs. This makes it quick and easy to use, but trip over it and you have two hot wires loose on the floor. Make a strain relief for the power cords. Or put it in a box so that you can yank it and it can't come out.

This is one of value for money ESP32 board that has all standard ESP peripherals . Apart from that it has also a SDCard on which one can store logs,configuration,default firmware-binaries (in case flash space is becoming too small). Need to check fully after I program this chip
