Python library for controlling Saleryd HRV system

Python library for controlling Saleryd HRV system using the built in websocket server used by Saleryd HRV Homeassistant integration https://github.com/bj00rn/ha-saleryd-ftx

Maintains a reconnecting websocket to the system.

Supported devices

LOKE1/Loke Basic/LS-01 using control system 4.1.5

Usage with asyncio as library

Read data

import asyncio
import aiohttp

from pysaleryd.client import Client

async def work():
    async with aiohttp.ClientSession() as session:
        async with Client(WEBSOCKET_URL, WEBSOCKET_PORT, session) as hrv_client:
            await asyncio.sleep(2) # wait a bit for some data
            print(client.data)

loop = asyncio.new_event_loop()
loop.run_until_complete(work())

Read data using callback

import asyncio
import aiohttp

from pysaleryd.client import Client

def handle_message(data: dict):
    print(data)

async def work():
    update_interval = 10 # call handle_message every 30 seconds
    async with aiohttp.ClientSession() as session:
        async with Client(WEBSOCKET_URL, WEBSOCKET_PORT, session, update_interval) as hrv_client:
            hrv_client.add_handler(handle_message)
            await asyncio.sleep(update_interval +1 ) # wait around a bit for data

loop = asyncio.new_event_loop()
loop.run_until_complete(work())

Send control command

Command syntax can be found by dissecting websocket messages in the built in web ui

import asyncio
import aiohttp

from pysaleryd.client import Client

async def work():
    async with aiohttp.ClientSession() as session:
        async with Client(WEBSOCKET_URL, WEBSOCKET_PORT, session) as hrv_client:
            await hrv_client.send_command("MF", 1)

loop = asyncio.new_event_loop()
loop.run_until_complete(work())

Troubleshooting

• Confirm system is connected and UI is reachable on the local network. Follow steps in the manual.
• Confirm websocket port by connecting to the UI using a browser and take note of websocket port using debug console in browser. 3001 is probably default
• The system HRV system can only handle a few connected clients. Shut down any additional clients/browsers sessions and try again.
