Here is where I'm at 
1) clean install of Rasbian Jessie (November 2015) 
2) Installed Node-red for RasberryPi 2 
3) Followed instructions for auto boot (Making Node-RED autostart on boot (optional)
4) Tested "First Flow - Blink - gpio" Working OK 
Now I'm trying to get my DHT11 reading 
1) Installed BCM2835 1.47
2) Installed npm install node-dht-sensor and npm install node-red-contrib-dht-sensor







When I run it I get 

TypeError: Failed to initialize

This is where I am confused in the instructions; 
Note that this node requires that node-dht-sensor is installed and accessible from Node Red. Since this requires accesss to low-level parts of the Raspberry Pi, you must run your flow with superuser access.
Is that my problem ?

Possibly, the easiest way to see is to try ;-)

I'm assuming you installed pm2 to outrun start node-red.

So you need to stop it running

pm2 stop node-red (This will temporarily stop node-red but it will still restart if you reboot)



then try starting node-red with sudo 

sudo node-red-pi --max-old-space-size=128


one thing to remember is that by default the above will look for the flows file within User directory : /root/.node-red

so if you want to pick up your existing flows file you would need to add the path afterwards


e.g

sudo node-red-pi --max-old-space-size=128 --userDir /home/pi/.node-red/

Yes probably. If you stop it running then run it from the command line as root .eg
  sudo node-red
does it then work ? If so then yes, that's the problem.

Marks answer much more complete ! So ignore mine...

Thanks Mark, 
                    That worked! I stopped pm2 and restarted with sudo node-red-pi --max-old-space-size=128 --userDir /home/pi/.node-red/
How do you recommend I proceed with getting Nodered to autostart? Can I edit pm2 or should I remove it and try and alternate configuration?

That's up to you.

The some of the alternatives start node-red on boot up.
The advantage of pm2 is it will also restart pm2 after a crash.

Either way you'll need to remove the node-red from pm2

pm2 stop node-red ( if you've rebooted)
pm2 save

Ok, 
      Working on my new install with Jessie img c/w Nodered installed. 
I ran the NPM installer as per instructions and installed Installed BCM2835 1.47
Now I can't get node-dht-sensor to install. I get the following error;

pi@raspberrypi:~/.node-red/node_modules $ npm install node-dht-sensor

Have you tried to install an earlier version?

e.g

npm install node-dh...@0.07

Hey Mark, 
               I have a lot to learn. How would one know older versions are available ? it doesn't seem that clear on github. Does it not just make sense to install the most current version of node.js,nodered and npm? or will I still run into version issues? 
Jeff

If you then look at the github page for the node-dht-sensor

Look at the open issues, you'll see someone had almost the identical issue as you 

and the author wrote:"You should not use node-dh...@0.0.8 with older versions of node (i.e. before v12) that´s why you are getting these errors."

Then if you look at the github page of the node-red-contrib-dht-sensor

the package.json file lists the dependencies on other "libraries" that the node-red-node requires.
(it should also enable npm to auto install the dependencies as well)

this shows: 

"dependencies": {
     "node-dht-sensor": "*"
  }

the star means any version.

So the author of the node-red-node says it should be OK to use an earlier version (as there would be a minimum version specified if they know there was a problem)
And the author of the required node-dht-sensor suggests to install a version before 0.0.8


You could upgrade the version of nodejs following the instructions here:  http://nodered.org/docs/hardware/raspberrypi.html#upgrading
Personally I wouldn't go to the latest version of node.js - see the big yellow box on this page http://nodered.org/docs/getting-started/installation.html
You are likely to get different errors with other nodes. 

But you could install v0.12.x  I'm happily running some v.0.10.x and some v.0.12.x nodejs versions on various RaspberryPis and have only once hit a problem like this.

It isn't ideal that node-red-contrib-dht-sensor has such a liberal approach to the underlying module version. If node-dht-sensor were to release a major version change, which could introduce breaking API changes, then it would break the node-red node.

With our core nodes we try to be as specific as possible with dependency versions so we can properly manage version changes.

From what you've said, I think it is very questionable that node-dht-sensor made a release that would break existing users on node 0.10.x but only changed the last digit of their version string - that isn't proper semantic versioning (see semver.org).

Regardless, this is academic for you Jeff. I'm sorry you've had the issues you have had. I think you've hit a bit of a perfect storm of problems - each of which is explainable in isolation, but the sum total has made it a frustrating experience for you.

The fact the apt-installed version of node.js is so back level (0.10.x) is a real shame - but also completely out of our hands (nor is it the RPi guys fault - they take from Debian Jessie).

I have raised a pull request against the contrib node to pin the dependancy back to version 0.0.6 that does compile on node v0.10.x.

In the interim you can install a copy from here

      cd ~/.node-red
      npm i git+https://g...@github.com/dceejay/node-red-contrib-dht-sensor

I have tested that against a clean Pi preinstall. (after adding the bcm library of course).
You have to run node-red as root but apart from that it works ok.

Thanks Dave for your effort! 
                                          I stuck with it have NR running with current version of node.js. I am happy as I have my Neurio energy reporting to EMONCMS and also getting temp/humid from my DHT11. 

Now I am working on my auto start that will allow these all to run with no errors. I'm back to following the PM2 instructions. I've tested several start strings with no success. Some how I need to get 
 
sudo node-red-pi --max-old-space-size=128 --userDir /home/pi/.node-red

into PM2 as it is the only start up that enables the bcm8235 (if that makes sense)

You should be able to do this with just systemd. See my attempt in Peter's debugging thread.

Hi Julian, 
              Thought I'd give it a try....I got the failed save and then get this error;
pi@raspberrypi:~ $ sudo systemctl daemon-reload && sudo systemctl enable nr-live2
