EHOSTUNREACH with Switch

[brunolalb]

Hello, It's been a few weeks of research and I couldn't find a solution yet.

My home wifi network is a Mesh from DLink with one main device and one extender. I have many smart devices (switches, plugs, dimmer, WLED strips, thermostats) which work just fine. Almost all of them have Fixed IPs configured on the WiFi router.

I have automatized some things using NodeRed on a RasPi-similar system running Ubuntu and connected to the main router via cable, mostly to "attach" a switch to a WLED.

One device isn't working properly, a 2Gang Switch. I can control it via the Tuya app. I can see it when I run "tuya-cli wizard", but the node on the Node Red cannot connect to it.

When I run DEBUG=* tuya-cli get --id '<device_id>' --key '<local_key>' --full

I get the following output:
