Read the SX631 meter with Slimmelezer and Tasmota
I've ordered the Slimmelezer+: https://www.zuidwijk.com/product/slimmelezer-plus/
How to use it with Tasmota? https://github.com/helander/tasmota-slimmelezer
- You need to build your own firmware. https://tasmota.github.io/docs/Compile-your-build/ I've used Tasmocompiler with the following custom parameters:
#ifndef USE_SCRIPT #define USE_SCRIPT #endif #ifndef USE_SML_M #define USE_SML_M #endif #ifdef USE_RULES #undef USE_RULES #endif #define USE_SML_SCRIPT_CMD #define USE_SML_SPECOPT #define SML_REPLACE_VARS #define USE_TCP_BRIDGE
- OTA your Slimmelezer+ with the .bin tasmota file
- Connect you Wifi, if it wasn't in your config
- Module configuration: Generic(18)
- Tools, Edit Script: find in the script file.
