@sweebee Yes?

@gleno0h i have tried this but unfortunately it’s not getting better though - this is the tail from the npm-logfile

any other idea?

Agree, Thanks @SaxnPaule for your excellent contribution

A way to connect a WS2812-strip or ring directly to the Raspberry Pi.

What you need:

Some WS2812 LED´s Node Red Plugin node-red-node-pi-neopixel Possibly an external power supply.

If you want to use a lot of LED´s, you have to use an external power supply. You have to connect the Ground of the Pi with the Ground of your power supply. In my case a ring with 16 LED´s works fine directly to the 5V of the Pi.

The data line goes to GPIO18.

In Node Red install the plugin node-red-node-pi-neopixel via “Manage palette”

@bill-blacksoll said in i2c 1-Wire Expansion Module DS2482S:

But owjs plunin always shows : error read value of OWFS sensor temp1: Error: connect ECONNREFUSED 127.0.0.1:4304

I think it might be a configutaion. See https://github.com/mspetik/pimatic-owjs/issues/1

Dar-S created this issue in mspetik/pimatic-owjs closed Error: connect ECONNREFUSED 127.0.0.1:4304 #1

BME280 need to have possibility to calibrate. It is notorious for overheating issues, and I dont trust humidity as well…

yeah, first i thought also something like that, but i’ve really tried all possibilities. i can start mplayer from pimatic rule with no problem, but if i start it that way, it dont listen to the pipe…

to start i use these rule:

execute “mkfifo /tmp/fifofile” and execute “mplayer -slave -input file=/tmp/fifofile http://stream.laut.fm/charon”

for change volume that:

execute “echo volume -1 >> /tmp/fifofile”

ps: how can i post code in this forum??
