====Tasmota==== {{:tools:tasmota.jpg?200}} \\ \\ {{:tools:tasmota-nodemcu.jpg?200}} Tasmota is firmware providing support for various devices attached to an ESP8266/ESP32. It has a HTTP interface and MQTT support. It was initially designed for SONOFF power switches but can be used with any device to give an MQTT enabled WIFI temperature monitor, for example. === Install === Example installation on a WEMOS D1 Mini Lite. Visit the [[https://ota.tasmota.com/tasmota/release/|Tasmota releases]] page to determine the available firmware. Fetch the sensors firmware for the ESP8285. wget "https://ota.tasmota.com/tasmota/release/tasmota-sensors.bin.gz" gunzip tasmota-sensors.bin.gz Plug the board in via USB and program with [[:tools:esptool|ESP-Tool]] esptool.py --port /dev/ttyUSB0 write_flash -fs detect -fm dout 0x0 tasmota-sensors.bin esptool.py v4.6.2 Serial port /dev/ttyUSB0 Connecting....

If the board was previously blank then it will create an access point to enter WiFI details, else it will re-use old settings. ===Configuration=== Boards without settings will require configuration and those with old settings have no further configuration to do. ==Pre config=== When the target boots connect to its open tasmota Wifi access point and visit the web interface [[http://192.168.4.1/|here]]. Enter your SSID and password and the target will reboot with the new WiFi credentials. ==Post config== Connect to the device on your LAN and change the device type, Eg. Generic and then save settings. It will reboot. ==Information== From the information page, see something like this Generic Tasmota Program Version 13.1.0(sensors) Build Date & Time 2023-08-15T07:59:54 Core/SDK Version 2_7_4_9/2.2.2-dev(38a443e) ==Sensor== To add an I2C sensor (Eg. BMP280) wire up the board and change GPIO4 to SDA, and GPIO5 to SCL. The device will reboot. ==BMP280== Generic Tasmota BMP280 Temperature 21.3 °C BMP280 Pressure 1022.8 hPa ===WEMOS NODEMCU V3=== Two boards can be seen above in the photo, they differ only the Flash device used and both are 32Mbit in size. ^Type^Manufacturer^Device| |0x164068|BOYA MICRO|BY25Q32CSIG| |0x164020|XMC|XM25QH32C| BY25Q32CSIG opcode 0x9F (see data-sheet page 17) XM25QH32C opcode 0x9F (see data-sheet page 20) ^Bits^Ident^Type^ |16:23| ID15-ID8| Ident low byte | |8:15| ID7-ID0 | Ident high byte | |7:0| M7-M0 |Manufacturer| Tasmota versions newer than [[https://ota.tasmota.com/tasmota/release-12.2.0/|12.2.0]] for ESP8266 do not work correctly with the XMC SPI flash.

The console shows the chip rebooting with watchdog reset errors continuously. To upgrade attach a console to the ESP8285 by connecting a UART adapter in 3V mode to the Rx/Tx and GND pins on the board. Power up with the DC input. To enable flash erase/write, power off and short IO0 on the pad. Power up with the DC input. ==Write flash== Writing was unreliable and needed lots of attempts (do not give up). esptool.py write_flash 0 tasmota.bin --no-compress esptool.py v4.6.2 Loaded custom configuration from /home/darron/Tasmota/ESP8266/13.1.0/esptool.cfg Found 1 serial ports Serial port /dev/ttyUSB0 Connecting...
