This way, I could already close the box again. I like that, after initial flashing the OTA-Update (Over The Air) works. Andreas Hölldorfer already found out the mapping, though it seems that he’s got a different revision of the hardware. The “Generic ESP8266 Module” header file doesn’t know any readable names for the pins, so I had to use the numbers. But the only thing I had to adapt for using RGB on this device instead of my usual hardware were the IO-Pins. ‘Almost’, because till now it just does RGB, not RGBWW. I mentioned to have an almost fully working firmware for my use, based on the excellent Homie for ESP8266 framework.
Given the growth of IoT applications using the MQTT protocol as a base and the Node-RED platform, we have created a possibility for industrial devices or devices using Modbus RTU protocol (RS232 or RS485) to interact. By trialcommand in ESP8266 HMI Panasonic Test Gateway April 7, 2017. I just connected my USB-serial-interface between computer and the module (without connecting external power to it, I don’t know if that would have damaged anything), and I configured the module in the IDE like this:Īfter connecting RX and TX in the right way, I was able to upload my firmware. Gateway: ESP8266 Modbus RTU MQTT + HMI Industrial Panasonic.

When the jumper is set, it’s possible to flash a new firmware over the serial interface. Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and. And right next to that is a connector that literally wants a jumper to be set on it. On the PCB - and thanks to great photos in most of the offering shops I knew that ahead of the purchase - is a well labeled serial interface. Andreas Hölldorfer did it, and he wrote about it. It’s just questionable if it’s possible to get my own firmware to this off-the-shelf-device…įlash-jumper set, connected to serialI’m not the first one to try that. This module would be a great platform to use it on. I’m fooling around with a firmware for small WiFi-devices for a while, that communicates with the MQTT protocol. This module is driven by an ESP8266, so it works in a WiFi network. The main advantage is, that MQTT supports retaining of messages. My DIY-one is controlled via infrared remote control. MQTT enabled ESP8266 firmware for the famous H801 This firmware enables the H801 to subscribe to dim commands via MQTT. This device controls RGBWW, meaning that it would be possible to attach for example a warm and a cold white strip, in addition to the RGB one. My own projekt does that on four channels: RGBW. It does almost the same: it controls the brightness of LED strips.
Two years ago I built a project that runs by the name of IRlicht (I was sure that I published it at that time - seems that I still have to). There’s also an app that controls the lamps from a phone, but I didn’t even bother to test that. It’s called H801Wifi, and it’s sold for nine Euros. H801 Wifi in caseI don’t remember how I found this, but a while ago I ordered one of these modules from china.
