pysaleryd
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 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)
Read data using callback
import asyncio
import aiohttp
from pysaleryd.client import Client
def handle_message(data: dict):
print(data)
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
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 with aiohttp.ClientSession() as session:
async with Client(WEBSOCKET_URL, WEBSOCKET_PORT, session) as hrv_client:
await hrv_client.send_command("XX", 1)
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.
