Password Support?

[alexanderloy]

Switchbot allows you to set a Password, could you add this so a password can be used?

[devWaves]

if you want to use password you can make some minor code change to the python code

Example password = 'testpassword'

Steps 1) get the CRC32 4 byte hexadecimal value for your password ( you can use an online tool like this https://crc32.online/) 2) testpassword = 9dcb7360 3) Modify this part of the code ....

if act == 'Turn On':
    con.sendline('char-write-cmd ' + cmd_handle + ' 570101')
elif act == 'Turn Off':
    con.sendline('char-write-cmd ' + cmd_handle + ' 570102')
elif act == 'Press':
    con.sendline('char-write-cmd ' + cmd_handle + ' 570100')

to this...

if act == 'Turn On':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360' +'01')
elif act == 'Turn Off':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360' +'02')
elif act == 'Press':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360')

static byte bArrayPressPass[] = {0x57, 0x11, NULL, NULL, NULL, NULL};
static byte bArrayOnPass[] = {0x57, 0x11, NULL , NULL, NULL, NULL, 0x01};
static byte bArrayOffPass[] = {0x57, 0x11, NULL, NULL, NULL, NULL, 0x02};
static byte bArrayGetSettingsPass[] = {0x57, 0x12, NULL, NULL, NULL, NULL};
static byte bArrayHoldSecsPass[] = {0x57, 0x1F, NULL, NULL, NULL, NULL, 0x08, NULL };
//static byte bArrayBotModePass[] = {0x57, 0x13, 0x64, NULL, NULL, NULL, NULL, NULL};     // Other github documentation shows this to be the array for setting mode with password (firmware 4.5, 4.6)
static byte bArrayBotModePass[] = {0x57, 0x13, NULL, NULL, NULL, NULL, 0x64, NULL};       // The proper array to use for setting mode with password (firmware 4.9)

These implementations from SwitchBot-MQTT-BLE-ESP32 suggests that second bit should be 0x11 not 0x01 when controlling bots with password. I only tested press signal, but other implementation seems plausible.

Thus, the correct code should be the following:(I haven't tested the python implementation yet. Tell me if this is wrong)

if act == 'Turn On':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360' +'01')
elif act == 'Turn Off':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360' +'02')
elif act == 'Press':
    con.sendline('char-write-cmd ' + cmd_handle + ' 5711' + '9dcb7360')

yep, my bad. should be 11 not 01

That small change also assumes you use the same password for all bots

@spinachpasta @devWaves If you would like to submit a PR, you can.

@donavanbecker I'm not using this implementation since I use my ESP32 code, I just happen to be browsing and mentioned a quick fix

The sample I provided would overwrite the default no-password option and isn't setup for dynamics password so it would take a bit more work for a full PR
