HS300 returns 5 children (plugs), when 6 is expected

The HS300 has 6 outlets.

When I send command: ./tplink_smartplug.py -t HS300 -c info

I receive: Sent: {"system":{"get_sysinfo":{}}} Received: {"system":{"get_sysinfo":{"sw_ver":"1.0.10 Build 190103 Rel.163517","hw_ver":"1.0","model":"HS300(US)","deviceId":"<obfuscated>","oemId":"<obfuscated>","hwId":"<obfuscated>","rssi":-68,"longitude_i":<obfuscated>,"latitude_i":<obfuscated>,"alias":"TP-LINK_Power Strip_0320","mic_type":"IOT.SMARTPLUGSWITCH","feature":"TIM:ENE","mac":"<obfuscated>","updating":0,"led_off":0,"children":[{"id":"<obfuscated>00","state":0,"alias":"outside fan","on_time":0,"next_action":{"type":-1}},{"id":"<obfuscated>01","state":1,"alias":"inside fan","on_time":1352807,"next_action":{"type":-1}},{"id":"<obfuscated>02","state":1,"alias":"Plug 3","on_time":1398685,"next_action":{"type":-1}},{"id":"<obfuscated>03","state":1,"alias":"Plug 4","on_time":1398685,"next_action":{"type":-1}},{"id":"<obfuscated>04","state":1,"alias":"Plug 5","

as you can see it stops at Plug 5, and it doesn’t finish

When I change data = sock_tcp.recv(2048) to data = sock_tcp.recv(4096)

I then receive all 6 children. Was this the correct fix?

I just spotted the formatting was wrong on my comment, updated. Don’t call decrypt on data2[4:] as that’s where the four bytes are being dropped, you need to append data and data2, then drop four bytes of both, it’s this line that you need “decrypt(data[4:] + data2)”

For testing I used the history functions which returns much larger values and so hit this case most invocations rather than simple reads which rarely exhibit it.

Thanks Ashley, I tried some of your code, you’re doing something with json which wasn’t part of the original, so I left it out. As you can see, I am missing 5 bytes in the “id” for outlet id ending in “404”.

    abc002 = abc010 = "b"
    sock_tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock_tcp.settimeout(2)
    sock_tcp.connect((ip, port))
    sock_tcp.send(encrypt(cmd))
    data = sock_tcp.recv(2048)
    abc001 = decrypt(data[4:])

if (abc001[-1] != '}'):
        data2 = sock_tcp.recv(2048)
        abc002 = decrypt(data2[4:])
sock_tcp.close()

    abc010 = abc001 + abc002

    print "Sent:     ", cmd
    print "Received: ", abc001
    print "\n\n\n\nReceived2: ", abc002
    print "\n\n\n\n ", abc010
