node-red-node-ping

A Node-RED node to ping a remote server, for use as a keep-alive check.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-node-ping

Gotcha

On some versions on Raspbian (Raspberry Pi) ping seems to be a root only command. The fix is to allow it as follows

sudo setcap cap_net_raw=ep /bin/ping
sudo setcap cap_net_raw=ep /bin/ping6

Pings a machine and returns the trip time in mS.

Returns boolean false if no response received within 5 seconds, or if the host is unresolveable.

Default ping is every 20 seconds but can be configured.
