How Do I Watch for HA Start & Shutdown Events in Node-RED

[fishertimj (Tim Fisher)]

I’m having some trouble figuring out how to watch for “start” and “shutdown” events in Node-RED. I have this working great as a YAML automation but I’m moving everything to Node-RED and having some trouble figuring out what exactly to watch.

Any advice?

TYIA!

Have you added an “Events All” node and put a debug on the output?
Change the setting in the debug to “complete msg object” and you should see everything coming out of HA.

The following services are available under the domain homeassistant

and these are for hassio

This does work with the start events , but there is no event recevied when using shutdown or reboot

I ended up using this:

Node-RED, trigger sequence on HA Start

Keep that automation, but have it trigger an execution of a shell command: ha_running: 'curl http://localhost:1880/hass/running' (Ensure the /hass/running matches the below): In Node Red use a http in node like this: [image] So basically, when HASS starts it immediately calls that node in Node Red, which can then flow into whatever actions you want. Mine is a Slack alert: [image]

I have another solution that doesn’t require an automation within HA.

There’s a global boolean within the homeassistant object called isConnected. I have a inject node firing the status of that boolean as the payload every second. An RBE node watches for changes (ignoring the initial value). That feeds into a switch node that routes the message based on whether it’s true or false. Then do whatever based on that info. I send a telegram message on both the false and true conditions (Home Assistant Offline/Online). The flow above omits the telegram.

Does anyone knows how to stop an automation from triggering (home or not_home) after a HA restart?

[fishertimj (Tim Fisher)]

Is your Telegram messaging being handled exclusively within Node-RED? Wouldn’t it have to be since you can’t call the notify service handled by HA when HA is down?

Ya, there’s a couple threads on here about setting up and using Telegram. And I looked at some of the other non-NR Telegram threads for ideas and help too.
Here’s one of the NR Telegram setup threads

[HowTo] Setting up a Telegram Bot for all your Home Automation messages

Hi to you all! Just want to share a simple HowTo to setup a Telegram bot for all your messages from, and to your home automation services. For example, I use three separate Telegram-bots: Logging-bot for, ehh, logging. No sounds or pop-ups when messages arrive on my phone/tablet/desktop. Status-bot for state-changes like Home, Away, Armed and so on. Just a ‘beep’ when messages are received. Alarm-bot for alarm and emergency messages, including pictures from cameras in breached zones. With…

Let me know if you need any further help.

Just wanted to come back to say this has worked VERY well for me. Thank you!! Really great solution!

It was working great for me as well, but recently I’ve been getting a lot of duplicates that the rbe node doesn’t seem to be catching. Need to investigate when I have time.
