Missing Power Data - again

[alexandergeiler]

Hi jasonacox,

I am getting again now power data (you helped me in the past already with the case #17

I have try to do the same steps again. But it is not working.

I have executed the 'python -m tinytuya wizard' command:

Any idea why I do not get the power data via plugpower.py? I can see the power data in the tuya-raw.json file...

It seems the solution is in jasonacox/tinytuya#55

pi@pi-vz-be:~/tuyapower $ python test2.py
input text = CRsAApUAAJY=
decoded = b'\t\x1b\x00\x02\x95\x00\x00\x96'
CRsAApUAAJY= converts to 0000100100011011000000000000001010010101000000000000000010010110
----- 3 values -----
V = 0000100100011011 = 233.1 V
I = 000000000000001010010101 = 2331 mA
P = 000000000000000010010110 = 150 W
pi@pi-vz-be:~/tuyapower $

But how can I get the payload via the plugpower.py?

[jasonacox]

Hi @alexandergeiler - good job on troubleshooting. Can you share the code you use for test2.py? Essentially you need to add that to plugpower.py to make it work. If you can think of a clean way to add this in for others using plugpower.py with this smart meter, please feel free to submit a Pull Request so we can give you credit. Otherwise, the test2.py code and/or any information on what you think we should do to edit plugpower.py would be helpful.

[alexandergeiler]

it´s your code :-)
I just change the "text" to my value.
I will have a look where I can add this in plugpower.py.

import base64

# Take one of the DPS values 
text = 'CV4AAPoAAC0='
field = text.encode('ascii')
print("input text = %s" % text)

# Decode base64
z =base64.b64decode(field)
print("decoded = %r" % z)

# Convert to binary - 64 bits
zbin = "".join(["{:08b}".format(x) for x in z])
print("%s converts to %s" % (text, zbin))

# Assume 2 int values are in the 64 bits
a = zbin[:32]
b = zbin[32:]
print("----- 2 values -----")
print("a = %s (%d)" % (a,int(a, 2)))
print("b = %s (%d)" % (b,int(b, 2)))

# Assume 4 int vlaues are in the 64 bits
a = zbin[:16]
b = zbin[16:32]
c = zbin[32:48]
d = zbin[48:64]
print("----- 4 values -----")
print("a = %s (%d)" % (a,int(a, 2)))
print("b = %s (%d)" % (b,int(b, 2)))
print("c = %s (%d)" % (c,int(c, 2)))
print("d = %s (%d)" % (d,int(d, 2)))
