As I am not into python programming, this is kind og a workaround; I assume that some small python code could extend the tojota code to a custom Home Assistant AddOn


Prerequisites

A Linux sever running python 3.6+

An (apache) web server

Pulling https://github.com/calmjm/tojota to the linux server

Changing the tojota code

I will not go into setting up the https://github.com/calmjm/tojota as such, but as the code does make date-marked files, I am changing the code to make a stic filename instead:

These lines are mine:

# coding=utf-8

odometer_file = odometer_path / 'odometer.json'

parking_file = parking_path / 'parking.json'

remote_control_file = remote_control_path / 'remote_control.json'

making sure is a static file each time, that is just overwritting.

I am running the code from cron:

tojota.sh
#!/bin/bash

cd /home/bnp
source /home/bnp/tojota/bin/activate
export PYTHONIOENCODING=utf8
cd /home/bnp/tojota
python tojota.py

Exposing data for the HA Rest service

I am making the files available on the local apache server; same server where Home Assitant runs:

➜  tojota git:(master) ✗ cd /var/www/html/mytoyota 
➜  mytoyota ls -l
total 4
lrwxrwxrwx 1 root root  45 May  4 19:35 odometer.json -> /home/bnp/tojota/cache/odometer/odometer.json
lrwxrwxrwx 1 root root  43 May  5 07:26 parking.json -> /home/bnp/tojota/cache/parking/parking.json
lrwxrwxrwx 1 root root  57 May  4 19:35 remote_control.json -> /home/bnp/tojota/cache/remote_control/remote_control.json
➜  mytoyota

Output of code

The output looks like this:

odometer.json 
➜  odometer git:(master) ✗ cat odometer.json 
[{"type":"mileage","value":34938,"unit":"km"},{"type":"Fuel","value":77.0}]
