tibber-local-lib 0.1.0

A library to fetch and decode SML data locally from Tibber Pulse

Tibber Pulse Local Library

tibber_local_lib is a Python library designed to fetch and decode SML data from Tibber Pulse / your SML energy meter locally.

Key Features:

• Operates entirely locally without relying on the Tibber Cloud API.
• No data fetching limitations, even if your internet service provider (ISP) is down.
• Developed quickly, so it may require enhancements. However, it works flawlessly for me with polling rates greater than 3 seconds (this is a limitation of the SML energy meter and may vary depending on the manufacturer).

Contributions are welcome! Feel free to enhance and improve this library.

Installation

pip install tibber_local_lib

Setting Up Tibber Pulse for Local Access

Initial Setup:

1. Pre-requisites:
   • Ensure your Tibber Pulse is already connected to Tibber and you can see data on your Tibber App.
   • Note the password on the socket of your Tibber bridge (visible when unplugged, beneath the QR code).
   • Plug in the bridge and wait for the LED to light up again.
   • Verify that you are still receiving data on your Tibber App.

Enable Web Server:

1. Configure the Bridge:
   • Power off the bridge twice in 2-second intervals and wait for the LED to light up green.
   • Connect to the bridge's WiFi using the noted password and navigate to the following URL in your browser: http://tibber_bridge/data.json?node_id=1. You may need to replace tibber_bridge with the correct hostname or IP address.
   • Log in with the username admin and the noted password. You will be presented with a web dashboard.
   • Navigate to the params page and locate webserver-force-enable.
   • Set webserver-force-enable to true under the params tab, then save the changes and click Store params to flash at the bottom of the page.
   • Power cycle the bridge.
   • Tibber will still be able to fetch data from the bridge, and now you also have local access 👍.

Usage

from tibber_local_lib import SMLDecoder

password = "your_password" # 'XXXX-XXXX' from your QR-Code
url = "http://tibber-host.fritz.box/data.json?node_id=1" # change the hostname or replace it with your IP
auth = ('admin', password)
tibber_pulse = SMLDecoder(url, auth)

meter_id = tibber_pulse.fetch_meter_id()
print(f'Device ID: {meter_id}')

consumption = tibber_pulse.fetch_live_consumption()
print(f'Current Power (W): {consumption}')  # Output: total live power in W

total_consumption = tibber_pulse.fetch_total_consumption()
print(f'Total Consumption (Wh): {total_consumption}')  # Output: total consumption in Wh

tariff1_consumption = tibber_pulse.fetch_tariff1_consumption()
print(f'Tariff 1 Consumption (Wh): {tariff1_consumption}')  # Output: tariff 1 consumption in Wh

tariff2_consumption = tibber_pulse.fetch_tariff2_consumption()
print(f'Tariff 2 Consumption (Wh): {tariff2_consumption}')  # Output: tariff 2 consumption in Wh

Device ID: 0901454d41200099e91f
Current Power (W): 1530.2
Total Consumption (Wh): 19311451.7
Tariff 1 Consumption (Wh): 19311451.7
Tariff 2 Consumption (Wh): 0.0
