Enhancement Request for someone to add/test support for a small display such as the M5Stack Core

[jsmath]

I think this would be a really cool use case for a small display/readout of the battery information for the Victron smart shunt. I found the following project which seems similar enough that it may be possible to add support for the display without too much extra work. I can't test as I don't currently have an M5Stack Core.
https://github.com/koenvervloesem/ESPHome-Heart-Rate-Display

One limitation with the above link would be not being able to run wifi at the same, which I think is acceptable for the use case of just viewing battery information on a display in an rv/camper when on the road. Another esp32 device could be used without a display when requiring wifi and the M5Stack could be powered off to ensure it is not connected to the victron bluetooth.

This is already possible thanks to the ESPHome project. It has support for a lot of different displays. You need to write your own lamda automation for the data displayed. I have multiple displays showing the state of the shunt and solar charger.

Thanks for the reply! What displays do you use or recommend? Are you able to share your config/code?

Depends on the need and what other information you want to display.

I have one e paper for lower power display and a second small TFT display which is only active on demand.
I played with 5 different displays in various sizes and with different features.

It greatly depends on your use case. Like how much power is the display allowed to consume. What is the typical reading distance. Is it a bright environment with direct sunlight. Does it need always updated information or just infrequent updates. Maybe just switch on if a certain scenario occurs to inform you.

Depending on the answer this will impact the ideal display.

The M5 stack display are small displays and in my opinion pricey. I often use lilygo.
A lot of displays are supported by esphome project. That's the reason I wrote this component based on this project as it is a very flexible platform.
