Ethernet & WiFi controlled smart relay: 2 Relays, 2 Inputs

Description

This device has:

3 network Interfaces:
- A LAN (Ethernet) interface: Connects to a Local Area Network (LAN) using a standard Cat5e/Cat6 cable.
- A WiFi (Client) interface: Connects wirelessly to a nearby Access Point (AP)
- A WiFi (AP) interface: Devices such a smart phones, laptops, ... can connect wirelessly.
Note: This product can not bridge or route between interfaces.
Two relays: These can be remotely controlled. They operate independently, and have three operational modes:
1. Latching: Stays ON or OFF until next command.
2. Jogging: Switches relay state (ON/OFF) for a chosen interval. e.g. ON->OFF->ON or OFF->ON->OFF.
  Interval: 0.1 to 25.5 sec in 0.1 sec increments.
3. Delay: Same as Jogging, except:
  Interval: 1 to 65535 sec in 1 sec increments.
Two switch inputs: The current state is always reported via the management interfaces. Optionally, these inputs can control the relay(s).
The inputs are either:
1. ON: Input shorted to Ground, or
2. OFF: Input left Open circuit (there is a pull-up resistor), or raised to the same voltage used to power the device.

Three (3) Network Interfaces. All 3 network interfaces (LAN, WiFi-AP, WiFi-Client) can operate at the same time. Only one is needed to be operational.
Static or Dynamic (DHCP) network configuration. Network configuration can be set statically, or from a local DHCP server. Operates across router boundaries if gateway/DNS IP addresses are set; this means it can be managed from any location in the world.
Powerful WebGUI This device has a built-in web server giving the user full control via any web browser.
Integrates with IoT platforms. MQTT is built in to this device, so it can communicate with most IoT platforms such as HomeAssistant and openHAB
Schedules. The device includes powerful relay control based on set times. Times can be based on Time of Day, Date, and/or Day of Week.
Network time. The device sets the date/time using Network Time Protocol (NTP). The default NTP server is: pool.ntp.org
Mounting options. The rear includes a standard DIN rail mount. In addition, there are 4 holes for screw mounting.
IP watchdog. Relay control based on Ping timeouts to specified IP addresses.
