Wifi smart plugs

I don't know if anyone else has tried these but I recently obtained a couple of wifi smart plugs from amazon:

https://www.amazon.co.uk/gp/product/B07CVJYV3G

There are quite a few around using various brand names and based on the ESP8266 wifi chip I think. While the RF plugs that I use are generally pretty reliable these give another option and it would seem could be integrated with the HAH using python code from here:

https://github.com/clach04/python-tuya

I've just used a lua app to send data to my raspberry pi which is on the network anyway running the fauxmo.py script for amazon echo integration. There's a bit of an issue regarding having the app open on your phone because the devices can only have one connection at a time but it seems to work on an experimental basis so far.

Just something else which could help to keep this excellent system alive.

Would be a great addition to the HAH

Allan I have just purchased a wifi smart plug and am quite impressed with its speed to respond "Alexa" commands.

I wish I had the skills to write the software for the Home Automation Hub and incorporate/integrate these devices into the HAH platform.

Software to integrate

I'm not sure that my software skills are quite up to it either!

You need to install the python-tuya stuff from here:

https://github.com/clach04/python-tuya

and also the xaplib.py stuff from here:

http://www.dbzoo.com/livebox/hah_xap_python

You're welcome to have a go with what I have so far.

I've abandoned the lua script and just run this python script on my raspi on the same network as my livebox.

 

#!/usr/bin/python
from subprocess import *
import pytuya
import socket
import sys
import os
from xaplib import Xap
plugID = ['00','Xxxxx' ,'Xxxxx' ,'Xxxxx' ]
plugIP = ['00', 'Xxxxx', 'Xxxxx', 'Xxxxx']
plugKey = ['00','Xxxxx' ,'Xxxxx' ,'Xxxxx' ]
def hubTraffic(xap):
    xapmessage, port = xap.receive()
   
    parsed = xapmessage.split('\n')
    #print(parsed[6])
    if parsed[5] == 'class=xAPBSC.cmd':
        for _ in range(3):
            try:

                      if parsed[6].find('tuya') > 0:
                        state = parsed[12][-2:]
                        #print(state)
                        if state == 'on':
                           state = ' 1'
                        else:
                           state = ' 0'
                        #print(state)
                        tgt = parsed[6][-1:]
                        #print(tgt)
                        tgt = tgt+state
                        #print(tgt)
                        switchDevice(tgt)
                        #print(xapmessage)
                        break
            except socket.error, msg:
                        print('Socket Error')
                        socket.close()
                        exitcode = Popen('bscmsg -t dbzoo.livebox.twitter -x Tuya_plug_failure -s on',shell=True, stdout=PIPE).stdout
           
                        sys.exit()
           

       
       
def switchDevice(patt):
    data = patt
    t = int(data[:1])
    d = pytuya.OutletDevice(plugID[t], plugIP[t], plugKey[t])
    mess = 'Switching plug '+data[:1]
    print(mess)
    if int(data[-1:]) == 1:
        print('on')
        ndata = d.set_status(True) # This requires a valid key
    else:
        print('off')
        ndata = d.set_status(False) # This requires a valid key
   
Xap("FF000F00","dbzoo.livebox.tuyamanager").run(hubTraffic)

 

Obviously you need to put in your plugID, plugIP and plugKey in place of the Xxxxx fields. (leave the 00's in place at index 0)

 

With this script running I issus a "bscmsg -t dbzoo.livebox.tuya:plug.(1|2|3) -s (on|off)"

I haven't created these as bsc endpoints (although I suppose I could) I just rely on the script to pick up the xap message and react.

It switches the plugs pretty instantaneously when it works. As I said in my original posting there is a reliability issue with devices only able to maintain one connection at a time so if I am issuing frequent switching commands or if someone opens the app the script breaks :-(

 

So feel free to have a go and let me know how you get on.

here's a revised version

of the script. It's been running on a spare raspi for about a week now without breaking so it seems more stable and useable than the last one.

It attempts to reconnect if it fails to send the signal.
