pysmtreader (Python based SMT Reader):

A Python application to poll your smart electric meter, this application uses an undocumented API for Smart Meter Texas.

Huge thanks to u/keatontaylor for the API Details, without his documentation none of this would have been possible.

What it does

It polls Smart Meter Texas to get electric meter reading every hour (can be configured to read maximum twice per hour as restricted by SmartMeterTexas). Once read it will send read data to Home Assistant

Update config.yaml file

Update default config.yaml with your information mentioned below: Please update username, password, esiid, meter_number, base_url and access_token lines in the default config.yaml by removing "REPLACE" and providing your values otherwise application will not run!

Data Sent to Home Assistant

    current_state: Latest reading value
    prev_state: Previous reading value
    difference: This is computed difference from latest and previoud reading, so if you polling once an hour it is  hourly usage
    unit_of_measurement: KW
    odrusage: This is provided by smartmetertexas.com and most likely it is total since last day
    last_timestamp: Last read time in the format of 2020-05-27 14:30:01.674
