Build Custom firmware for Smart Device Sonoff Pow R2 (Flash Firmware)

Hello sir/Mam, I m new on freelancer, I'm working in a home automation company as a technical lead. I have 2 years of experience in Arduino and embedded system and IoT. I easily find the better way to deal with problem in my work. And trust me I will never disappoint you. I understand what you want, you want add some extra features in sonoff pow , if I'm right you want to operate device with any other app. These all things are okey. But there are one problem in sonoff devices the flash memory is limited, you can take it as there monopoly in business. So if you want to add some extra features then you need to change their flash also. For your convenience if you want, I can make a saprate device according you. You can discuss about your project in inbox. Thanks Anubhav Agrahari

Hello, How are you? I read your project description and I am interested in your job. As you can see my profile, I am a full-time developer and have just completed many projects. Specially, I have top skills for C/C++, C#, Java, Python programming and algorithms. (User friendly GUI and CLI). I am ready for Windows , Linux and MacOS. Will be provided HIGH QUALITY , HIGH SPEED , well-known comments and assistance. We can discuss more detailed idea and requirements on chat. Regards!!

Hello! Nice to meet you. I am interested in your project. I have experience on microelectronics, ARM, Arduino, Raspberry, PIC, ATMega and so on. I can do help you. And I want to cooperate with you. Tell me your opinion. Thanks. My regards.

How are you? I am a Senior Electronics and Embedded Engineer with the areas of expertise in Home Automation System and Embedded System, product prototyping, Schematic & PCB design and firmware development for systems. As I'm a Master of Computer Science, I have 10+ years of experience in technical projects, project leader including Industrial process control etc. - Microcontroller programming using STM32WB/STM32, ESP32/ESP8266, Arduino, BLE/Bluetooth, WiFi, Ethernet, Zig-bee, GSM/GPS/GPRS/GNSS, Z-Wave - Various LCDs & Sensors, I2C/I2S/SPI, RS232/485 - various PLC & HMI programming such as ADAM, Siemens, Delta, Mitsubishi - Various Servo/Motor control - Windows application & Algorithm development using UWP, C#, C/C++ - Circuit & Schematic & PCB design - Mobile app development for the Hardware So, I can take your project from concept to finished product. I will try my best to complete your projects asap, and I will provide the best services with the high quality. Thanks.

I can help you configure a custom firmware for sonoffs. I can guide you through the firmware flashing process. I am also a cloud developer so i can develop a complete server for you to connect your plugs using MQTT and then you can control it from anywhere. I been working as an IOT Developer for quite a while now would love to hear back!

I have worked as developer embedded system with microcontroller such as DSP, FPGA/CPLD, PIC, PLC and so on. In there years, I have experiences about electronics engineering, power converter, communication such as SCI, SPI, CAN, GPIB(Agilent equipment), GPRS(Sim800, Sim808, etc). Also I have experiences about Automatic control such as Motor Control, PI control, 2P2Z control, Hysteresis control, and so on. I have made many equipments.

Hello. I am a senior Microcontroller firmware developer and Electronic Engineer. I read your description and I am interested in your project. I have an experience developed the ESP8266 firmware for wifi, BLE, MQTT. I have developed the IoT used ESP32,ESP8266. As I am an electronic engineer, I can not only develop the firmware for arduino, PIC ,Atmega , STM32 ,ARM, DSP processors but also design the circuit and PCB using EAGLE, Altium Designer. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I hope we can discuss more details via a private chatting. I look forward to your response Best regards.

Hi, I can make the firmware for your r2 , i have been working on similar projects. What are your exact requirements ? Then we can further discuss anything useful . Thank You

Dear, I would like to have a discussion with you, because I need to understand your requirements clearly. Best Regards

hello. I am a seasoned ESP8266 and ESP32 dev. I have frequently used mqtt and ewelink. Please tell me more about the features you would like to add.
