Settings / Parameters

Note

Some of this settings apply to the WiFi interface and the ethernet interface (if available on your board and configured). If ethernet is connected, the WiFi connection will be disabled and it's settings will be transfered to the ethernet interface (also the other way around). The ethernet interface has higher priority.

WiFi Configuration

WiFi SSID

The SSID¹ / name of your WiFi network.

WiFi Password

Optional password for the access point, if required.

WiFi Hostname

The host name with which OpenDTU logs on to various services (DNS server, MQTT server, mDNS). This name must be unique in the LAN². The text %06X will be replaced internally by the ChipID of the ESP. This helps to keep the hostname unique. The hostname will be also used if the ESP is connected via ethernet.

Enable DHCP

If DHCP is enabled the OpenDTU will request it's network information like IP/Netmask/Gateway from e.g. your router. If you disable this function you have to enter these settings manually.

Static IP Configuration

IP Address

IP Address which is assigned to either the WiFi interface or the ethernet interface (if applicable). Format: xxx.xxx.xxx.xxx

Netmask

The Netmask which is assigned to either the WiFi interface or the ethernet interface (if applicable). Format: xxx.xxx.xxx.xxx. The default value for a Class-C network (which you have most likely should be 255.255.255.0).

Default Gateway

The default gateway which is assigned to either the WiFi interface or the ethernet interface (if applicable). Format: xxx.xxx.xxx.xxx. For a standard home network this should be the IP of your router (e.g. 192.168.178.1).

DNS Server 1

The DNS server which is assigned to either the WiFi interface or the ethernet interface (if applicable). Format: xxx.xxx.xxx.xxx. For a standard home network this should be the IP of your router (e.g. 192.168.178.1).

DNS Server 2

Please see DNS Server 1

mDNS Settings

Enable mDNS

Enables or disables the mDNS publication of the IP address and version the OpenDTU. This is useful to address the DTU in the network with its DNS name if no DNS server (e.g. on the router) is available. The generated mDNS name is composed as follows: <WiFi Hostname>.local.

WiFi Configuration (Admin AccessPoint)

AccessPoint Timeout

After each device restart, if no valid WiFi configuration is found or if the configured AccessPoint is not found, an internal AccessPoint is opened. In case that the Wifi configuration is valid and the infrastrcuture AP³ is reachable, the internal AP is closed after the time configured in this setting.
