I am getting "A network or server error"

[wyxsmarthome]

I flash my CE dimmer with Tasmota and upgrade to 8.5.0
Followed the steps to add the device as a 'Generic dimmer switch', but it gave me 'A network or server error' when I tried to control it.
In the console of the Tasmota, I see logging "07:31:10 RSL: stat/tasmota/RESULT = {"Command":"Error"}"

It seems now I can control it after set the module. But it has problem to return states

Any idea?

I have the same issue using a sonoff mini device running tasmota 9.1.0 with the generic switch as my device handler

I have the same issue using a sonoff mini device running tasmota 9.1.0 with the generic switch as my device handler

looking at the device handler's code and the st's configuration i could find that i might have a "DNI" issue, i'm just not sure about what's the meaning of DNI.

In st's tasmota configuration there's (!!!) by the side of the ip configuration, that's why i got to this point, but i'm still clueless of the issue

Do you have a physical ST hub v2 or v3?
Are the Tasmota device and ST hub on the same subnetwork?

[vfmunhoz]

it's a V3 hub and yes, they're in the same subnetwork.
looking further i just found out that the dni retrieved from tasmota's device is correct but the dni in ST's configuration is been resolved to null

if (childSetting(it.id, "ip") != null) {
    String dni = it.state?.dni
    descText = childSetting(it.id, "ip")
    if ((dni != null && dni != actualDni) || (dni == null)) {
        descText += ' (!!!)'
    }
}

this piece of code is where i'm currently checking, although i believe that i have just a miss configuration somewhere.
for some reason the String dni = it.state?.dni is returning null and probably that's causing the issue
