NETIO Condition & Rules

NETIO devices use a system of "Condition" & "Rules" which have to be configured separately. To configure even simple IP WatchDog you have to configure 2 tabs:

• IP Watchdog (with which IP address will be monitored)
• Rules (what to do if defined state happens)

This configuration system is somehow similar to NETIO Lua scripting, but you don't have to be a programmer.
Detailed description and examples on the NETIO Wiki - Local device scripting.

IP WatchDog (Condition)

The IP WatchDog is used to monitor connectivity to specified IP address (or text defined URL). NETIO devices sending periodically PING request to specified IP and then waiting for PING reply.

It's popular to verify internet connectivity (pinging LAN gateway / router). Second typical usage of IP WatchDog is to check functionality / failure any LAN connected device. No PING answer = device not working and let's restart it by power output. 
AN61 has 2 parts: :

• Part 1: One IP address - Restart output when IP device not reply to PING requests (device failure).
• Part 2: Two IP addresses - Restart output when both IPs do not reply at the same time (IP connectivity / router failure).

The Rule

The Rule functionality generally define <strong>NETIO device's reaction</strong> to specific situation / event (condition).

Based on the conditions the NETIO device can process these actions:

• ACTION on defined OUTPUT
  • 0 = TURN OFF
  • 1 = TURN ON
  • 2 = SHORT OFF
  • 3 = SHORT ON
  • 4 = TOGGLE - Changes the status from ON to OFF and vice versa
     
• Send alarm to NETIO Cloud service (icloud service can inform account user by email for example)

Part 2: IP WatchDog for 2 IPs

NETIO Device can also pinging in paralel to 2 different IP addresses / URLs (2 different Conditions) and trigger one Rule (Action) only when both IPs do not reply for defined time. Typical usecase of this is restarting of local Internet connectivity router.

In Part 2 NETIO device pinging in 2 parallel WatchDog tabs (NR06_WDT_1 / NR06_WDT_2) to 2 different IPs and one Rule (NR06_RULE) restarting Output 1 device if none of the IP addresses reply. The ping for both IPs is sent every 30s and waits 5s for device to respond. There are 5 consecutive timeouts tolerated before the ping is considered as failed. When the ping fails, Watchdog returns false and remains in ERROR state.

In case both of the defined WatchDogs are in ERROR state, the Rule is triggered which then restarts Output 1.


Part 2 is similar to monitoring 1 IP address, there are just 2 differences:

• 2 separate WatchDogs tabs are user in paralel (instead of one)
• Rule definition have to restart output only when both Watchdogs fail (do not receive ping answer).

a) WatchDog 1 configuration

WatchDog name: NR06_WDT_1

Code definition:

{
  "target": "192.168.1.51",
  "pingInterval": 30,
  "timeout": 5,
  "maxTimeouts": 5,
  "maxRestarts": 0
}

WatchDog 1 configuration in NETIO device web for AN61-Part2:

b) WatchDog 2 configuration

WatchDog name: NR06_WDT_2

Code definition:

{
  "target": "192.168.1.52",
  "pingInterval": 60,
  "timeout": 5,
  "maxTimeouts": 5,
  "maxRestarts": 0
}

WatchDog 2 configuration in NETIO device web for AN61-Part2:

c) Rule configuration

Rule name: NR06_RULE

Code definition:

{
  "conditions": {
    "operator": "AND"
    "WDT/NR06_WDT_1/FAIL": true
    "WDT/NR06_WDT_2/FAIL": true
  },
  "actions": {
    "OUTPUTS/1/ACTION": 2
  }
}

Rule configuration in NETIO device web for AN61-Part2:

d) Event activation

To trigger Rule action, you now need to disconnect both of the IP devices.

Note: Part 2 examples are named WatchDog configuration NR06_WDT_1 & NR06_WDT_2 (Checking 2 IP adresses) and Rule configuration NR06_RULE. These names are related to NRxx NETIO Rules - examples in NETIO Wiki.
