Temp sensor values not updated

[zerobase]

I have a DS18B20 connected to an ESP8266 (ESP12F; running the ESP Easy firmware). The ESP is spitting out temperature readings from the DS18B20, but they are not appearing in Domoticz (Version 2.3530; running on a raspberry Pi).

From a tcpdump I can see what command the ESP is sending to Domoticz:

However, Domoticz is responding back with a status: ERR:

Trying to run the same command in a browser also gives an error/

I have configured Domoticz to allow non username/password protected connections from the local subnet.

Anyone have a further idea what is preventing Domoticz from displaying the temperature updates? Is the command from the ESP formatted wrong?

Did you supply the portnumber the domoticzserver is running on? <ip:port>

Just tested this and I get

{
"status" : "OK",
"title" : "Update Device"
}

using 2.4598

Just found the problem.

In the devices tab there are two colums: IDX (column 2) and ID (Colum 4). Guess what, I configured the value for ID in the ESP instead of that of IDX ...

It is working now!
