Can NodeRed Do a Httping To ping a Webpage

[Mikefila]

Okay I guess the script fails and not the pi hence the need to ping a specific port? There are 2 ways I can think of going about this.

Go to the node red addon page then the config tab. Edit in yaml and replace the system packages entry with:

system_packages:
  - nmap

If you already have entries add it with another dash

system_packages:
  - moment
  - nmap

Save and restart. Go to the work space and pull out an exec node and use nmap

You should get back a similar message.

The other way would be to use a command line sensor and ssh into the pi to run

sudo systemctl status callattendant.service

It’s a little more involved but you should be able to create a binary sensor to tell if the service is running or not

Use this guide to setup shh access from HA to the pi.

SSH'ing from a command line sensor or shell command

I’ve noticed there’s a significant number of posts looking for help on this topic and the posters all seem to struggle with a few common issues. I realized I’ve been almost copying and pasting my responses on these topics so it seemed like a good case for a community guide. What will this cover This guide will walk through the process of getting a command which ssh’s into another machine to get some simple data ready to be included in a command line sensor. To keep it simple I’ll use the same …

Edit: if nmap works, if the service is up and running, the name of the service will be in the return string. If it is not it won’t show up. You can isolate this message with a switch node.
