My last update of Node Red is 18.1.1, I can't update to 19.0.2 as it says its only for aarch64 or amd64 architectures. So is Node Red no longer supporting Raspberry Pi?
Node-red does indeed install and run on the Raspberry Pi.
You might experience some difficulties on a 32 bit Pi (or a 32 bit operating system?) due to problems with supported node.js versions. It does still work though..
The current release of Node-red is 4.0.9. Maybe the issue you are seeing is a limitation of your chosen operating system, not Node-red?

Is that actually the home assistant addon version number? If so then perhaps HA has dropped support for old versions of the pi.
A few days ago I used the recommended pi install/upgrade script to install the latest node red (4.0.9) with nodejs 20 on a first generation pi zero.

I am running NodeRed v4.0.9 with NodeJs ver 20 without issue on a RPi 4B.
Cheers!
I run multiple Node-RED versions 4.0.9 on different devices and using different OS's:
Raspberry Pi 1B (armv6) on Bookworm and node v 20.15.0 and npm 10.7.0
Raspberry Pi 3B+ (armv7) on Buster and node v 18.20.6 and npm 10.8.2
2 instances in a TrueNAS jail (FreeBSD) and node 18.16.0 and npm 9.7.2
So, I don't see it, why it should not be supported anymore, but it depends also on the OS.
You will have issue's, if you try to use NodeJS v20 on Buster or earlier versions.
This is an HA problem, there are numerous reports of such problems with node red HA addon 18.1.1.
It's not a problem, it's intended. ARMv7 is no longer supported. This isn't limited to NR. 32bit support was dropped for esphome and vscode as well and other will follow over time. If you have a pi4/ARMv8 you can install the 64 bit version of home assistant.
Since this is a Node-red forum perhaps we should add:
If it is a problem for you, you can install Node-red on any Raspberry Pi running RPiOS.
You will lose the benefits offered by Home Assistant.

From what I see node.js has dropped support for 32bit systems. I'm guessing it's only a matter of time before actual NR follows suit.
Nodejs dropped official support for 32 bit some time ago - but there have been unofficial builds available - Index of /download/release/ - which we make use of.
However it does seem that there are no 32bit builds for nodejs v22 - so when that becomes the minimum level supported we will have to drop support also.
Node v20 ends maintenance April 2026 - so that will be the date.
Obviously you can continue to run on unsupported - if it ain't broke - don't fix it.

It is a problem for anyone wanting to run HA on older hardware.
... only if they have to upgrade.
It's getting to the point where HA will no longer run properly on older hardware. A basic install will run fine on a pi/older hardware but as soon as you add any local voice or ai processing, you're in nuc/64bit territory.
