Poll error

[Rafahorn03]

Hi,

I'm having errors when I try to poll my devices (len:22).

It works when I disconnect them from power or when I reboot my router, but some hours later, it stops working.

My devices are Tuya Smart Plugs, I have 4 and it does not work.

When I try pinging them, it does not work either.

Some devices seem to disappear from the local network after a while but they do seem to stay connected to the cloud.

A few things I would try:

• Update tinytuya to latest (pip install --upgrade tinytuya)
• Scan network with debug python -m tinytuya scan -d
• See if the devices still ping after they disappear (eg.. ping 10.10.20.30)

I tried it. As you said, they disappear, when I ping them they don't response, but I can see them connected to my router and tuya app still working.

Do you have other Tuya devices that don't do this?

Also, if it is related to a bug we have seen with some Tuya devices, the arp broadcasts stop working. If your router show the MAC address for the Tuya device, you can attempt to do a forced arp mapping on the host running tinytuya:

# set the IP to MAC mapping
sudo arp -s 192.168.31.5  0:1e:58:b1:64:40

# test it
ping 192.168.31.5

It is working with that. Thanks.
