I'm having trouble getting the bash script to feed updates via JSON to my Raspberry Pi. I can trigger the bash script manually and it seems to update the temperature sensor and PM2.5 sensor values the first time but then the temperature sensor updates to 0.0C and the PM2.5 sensor doesn't update again. I'm pretty sure I've set up the script to trigger at boot via a call to my 'startup.sh' script in my /etc/rc.local but after bootup is complete, doing a 'screen -list' doesn't show any sessions running unlike when I manually execute my startup.sh. Any suggestions?

TIA!
I had the same problem, but this helped me:

I have miiio working, I want to use the Wifi plugs.
I have read about power-plug and power-switch in the miio wiki but I don't know which commando should I use.
Anyone with an adapted script for the plugs can help me? I have the IPs but after that I'm a little bit stucked.

This one was my fault, wrong command sent.

For the other one, I had to make the require this way :
Not working :
const miio = require('miio');
Working :
const miio = require('../../../../usr/lib/node_modules/miio');

Could you replace the relative path ('../..') with a single / ? Basically :

const miio = require('/usr/lib/node_modules/miio');


For me the script from the first post does nothing - I ran the miio sync command (got no output), when I run the examples with 'node airpurifier.js IP command', nothing happens.

No, just a / will not work, already tried

If nothing is displayed, you have to add some lines to the JS file.

process.on('uncaughtException', function (error) {
console.log(error.stack);
});

Unfortunately, this did not help. I think there's something wrong with node or with miio in my case.

- when I tried 'npm install --save miio', I got a whole lot of errors.
- doing this with sudo ('sudo npm install --save miio') worked, but I still got warning about the version of node:

Code: Select all

wanted: {"node":">=6.0.0"} (current: {"node":"4.8.2","npm":"1.4.21"})
- When I run 'miio --discover --sync', it gives me no output at all, where can I find a logfile to check what went wrong?

You have to update node a new version.

Try
sudo apt-get update && sudo apt-get upgrade && sudo apt-get install node

Are you on Raspbian Jessie ?

I'm on Raspbian Stretch - the newer one. Did update, upgrade, install. I get: 'node is already the newest version (0.3.2-7.4).'

I'm on Jessie and node 6, there is maybe an issue with miio and node 7.
This is outside of my skills, sorry.

OK, I think I have this sorted out. I'll leave it here for others who can be struggling.

The key was to install the correct version of nodejs, as per this page:
https://nodejs.org/en/download/package- ... tributions

So, running:
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

My Purifier (using the script from this thread) sometimes sends strange values to the T+H IDX (temperature 0, humidity 0). Did anyone have similar issue? For now, I added an 'if', which does not send the 0/0 data, but maybe there is a better fix.
The aqi reading is correct, no strange values (unless the reading of 10 aqi means broken data - I get that a lot).
