integration on rpi4 in home assistant hass install

[janneman001]

I use the upspack v3.2p for quite some time now. Normal OS integration works fine. However i could not get graceful stuff in home assistant. That is why i created the integration below. Thanks for your nice upspack product.!

Below is a textcopy of upspack.yaml that i include as a package in homeassistant for the ups. I have the hass install. NB you need to do some hardware connections and amend the config.txt of the rpi4.
I hope it is of use.

upspack V3.2P integration for Home Assistant

see: https://github.com/rcdrones/UPSPACK_V3/blob/9eac086a66ff03e24fa8408de79b1a84dee0a41b/README_en.md

assumption is connection to rx/tx serial gpio of rpi4

as follows:

pin 6 gnd => upspack gnd

pin 8 gpio 14 txd => upspack tx

pin 10 gpio 15 rxd => upspack rx

for amending the config one should have root access to ha host.

see: https://developers.home-assistant.io/docs/operating-system/debugging/

en /mnt/boot/config.txt should be amended with:

enable_uart=1

on rpi4 bluetooth should be off since it uses the uart

dtoverlay=disable-bt

this file can be imported as package in home assistant.

it will create entities and automations for notification

input_text.ha_instance can hold the name of your instance for messages

identifier is used as a sort of check on receiving a valid message via the serial port

this could be made more resilient

current notification uses pushover integration. See below.
