A library for spying on Simarine devices and their sensor values using asyncio and Python

Based on the fantastic reverse engineering work of https://github.com/htool/pico2signalk

Only tested with Simarine Pico rev2

pip install spymarine

Make sure your Simarine device is configured to use AP or STA Wifi mode. It's not possible to connect via a local network while in REMOTE mode.

Run the following code on the same network that the Simarine device is connected to:

import asyncio
import spymarine

async def main():
    # Print all devices and their latest sensor values every second
    async with spymarine.DeviceReader() as reader:
        while True:
            await reader.read_sensors()
            print(reader.devices)
            await asyncio.sleep(1)

if __name__ == "__main__":
    asyncio.run(main())

• Switch into AP Wifi mode and connect to the Wifi
• Use reader.write_devices_cache(path) to create a devices cache
• Construct a DeviceReader and using the devices_cache_path argument while in STA Wifi mode
• See the Devices Cache Example

Note that the cache needs to be regenerated if any hardware of app configuration change.

• Non-ASCII characters in device names will not be represented correctly and replaced with a placeholder. A non-standard encoding seems to be used.
