Hi Bill,
I also have this connection refused problem with my plugs. So you mean, the mobile application Tuya has two methods to communicate with the devices:
- via TCP if Tuya app and plug are in the same LAN.
- via a MQTT broker provided by Tuya. App publishes a message to the broker topic which is listened by the plug.
Is that right? If so, is there any possible way to configure the MQTT broker address inside the plug? I assume it's fixed in the firmware.

@clach04 I also receive this error on a occasion & the device's state remains unchanged when it occurs. Typically, if I retry toggling the switch the device's state does successfully change (after a second or third try of toggling). So, I have a proposition, I think it'd be beneficial to add a try/except within a loop with range(3) to try changing the state up to three times to minimize these issues. Does that change seem like something you would allow?
For reference, I think this function is what we'd need to implement the proposed solution to.
def _send_receive(self, payload):
"""
Send single buffer `payload` and receive a single buffer.
Args:
payload(bytes): Data to send.
"""
for i in range(3):
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
s.settimeout(self.connection_timeout)
s.connect((self.address, self.port))
s.send(payload)
data = s.recv(1024)
s.close()
return data
except socket.error:
continue
