Can't find RENPHO ES-CS20M

[mikewilzn]

Has anyone had success pairing this scale? I've read the FAQ and nothing on there is the issue. It has never been connected to my phone at all. I don't really want to have to make an account with Renpho to use their app.

[oliexdev]

what is shown if you search for the scale in openScale? Could you attach a screenshot?

[oliexdev]

You never should pair the scale with your smartphone if you are using openScale, see https://github.com/oliexdev/openScale/wiki/Frequently-Asked-Questions-(FAQ)#why-is-my-scale-not-found But yes some scales activate Bluetooth only if you stand on it but then you should able at least to see it if you search for Bluetooth scale otherwise it is still paired with another device or Bluetooth is not activated.

Please reopen this, as the issue isn't related to whether or not it's paired with other apps -- the scale itself isn't discoverable, and most likely gets paired with based on a hardcoded MAC address in the official vendor apps. One way to fix this would be to allow users to manually enter the MAC address for the scale.

Total noob here, so please bare with me. I think I have one of those "it broadcasts but doesn't pair" and I can't find it in the debug log, or in my bluetooth menu, especially so because I don't see it in the bluetooth menu (yes I'm standing on it and it's in the same setting as what the real app supports, so it should be broadcasting)

I recently bought one of these devices and I figured out how to extract weight from them. I couldn't really confirm other metrics but here is the implementation. Note: I tested this on a PC that had a Bluetooth adapter. I did not have more time to investigative other metrics.

import asyncio
from bleak import BleakScanner

class EsCS20M:
    """
    This class gets the weight value from Renpho ES-CS20M
    I got other properties but did not have time to confirm so they are not included.
    """

    def __init__(self, mac: str, array: bytearray) -> None:
        self.mac = mac
        self.array = array

    def __repr__(self):
        return f"{self.__class__.__name__}(mac={self.mac}, array={self.array})"

    @property
    def weight(self) -> float:
        """
        Returns 16 bit register value and converts it into weight.
        """
        return ((self.array[18] << 8) | self.array[17])/100

    """

        self.device_mac = device_mac

    def detection_callback(self, device, advertisement_data) -> None:
        """

        if device.address == self.device_mac:

            _array = bytearray(advertisement_data.manufacturer_data[65535])
            c60_data = EsCS20M(mac=self.device_mac, array=_array)
            print(f"data: {c60_data} weight: {c60_data.weight}")

    async def run(self) -> None:
        await self._scanner.start()
        self.scanning.set()
        while self.scanning.is_set():

    loop.run_until_complete(my_scanner.run())
