This is what you can make with an expense of less than 20$
NOTE: 03/04/25 : I noticed issues with HiveMQ and Tasmota – I open a ticket in Tasmota forum https://github.com/arendst/Tasmota/discussions/23217 .
If you notice your Tasmota display rebooting , you need a patch .
Write me directly to info@dalybmswifi.com , I have a patched Tasmota 14.5.0.2 version that is working .
Original design was based on openHASP great project. openHASP is light, powerful, super easy but I found some limitations , expecially about MQTT TLS that prevents the openHASP based display to work with HiveMQTT for instance. This is why I moved to TASMOTA project. The dongle will support and generate config files for both openHASP / TASMOTA .
FEATURE SET:
– Open MQTT protocol, based on Haspmota scripting language you can customize your dashboard . ( you do, don’t ask me how to do 😉 )
– Multiple battery packs supported on the same display
( note, feature ready for openHasp project – work in progress to let TASMOTA display doing the same )
– Main Battery parameters shown on a single page
( hey guys I’m not a graph designer, I did my best, someone complain … this is a free project you can to better why don’t share with everybody ? )
– Charts will be available only on TASMOTA
( openHasp uses a version of LVGL libraries that does not support charts )
– you buy display on Aliexpress ad 10$ 😉
CURRENT LIMITATION
– openHASP : only MQTT non TLS is supported

| Two Displays linking to the same MQTT Broker | WORK In progress: Some Charts 😉 this is about BMS POWER |
