Get prices from Awattar API and update Tasmota timers to use the cheapest slot

awattar-tasmota

Overview

Very basic and poorly written lines of code to...

a. fetch the prices from the awattar API --> awattar.py b. configure Tasmota timers (ON/OFF) --> tasmota.py

The simple idea behind is:

• Get the cheapest slot of x (e.g. 5) hours, e.g. to turn on the boiler.
• Update the Tasmota timers 1 (ON) and 2 (OFF) based on the results.

Usage

To get the cheapest timeslots of 1...5 hours:

python awattar.py

To get the cheapest timeslot of x (e.g. 7) hours:

python awattar.py 7

For the use of tasmota.py the following environment variables need to be set:

• TASMOTA_HOST: e.g. "192.168.1.10" or "192.168.1.10:8888"
• TASMOTA_WEB_USER
• TASMOTA_WEB_PASS
• SLOT_HOURS (optional): slot size in hours (default = 5)

The script will then update timers 1 and 2 based on the results of the awattar.py script.

ToDo

• Error handling.
• Optional web interface credentials.
