Node-RED passing the wrong value? Check the message value, type and path before changing the logic. Try the local exercise and worksheet:
#NodeRED#Automation#TrainAndInspire
A flow you can see. Inject starts a message, Change adjusts it, and Debug lets you inspect the result. Practice locally. Explore training:
#TrainAndInspire#NodeRED#TechTutorial
Click it. See a result. Wire Inject to Debug, deploy, click Inject, and inspect the new Debug entry. Practice locally. Explore training:

Si quieres crear proyectos del #IoT no sufras con complicaciones del lado del #backend Utiliza #NodeRED y todo fluirá como el agua (flow like Water) 😄 Aquí tienes un tutorial de introducción para empezar con #ESP8266 y #Arduino
My first Node-RED book has been published! Really thank all contributors @knolleary@zuhitocom@joeartsea@1ft_seabass !
This book is very helpful for starting visual programming with Node-RED.
You can get it on Amazon. Check it out!

Si este verano estás aburrido puedes empezar con #NodeRED siguiendo este tutorial más el #podcast donde aprenderás a dar los primeros pasos con tu #RaspberryPi y hacer un ejercicio práctico. #Maker#DIY#IoT
Si todavía no conoces #NodeRED aquí tienes un tutorial para iniciarte en esta maravillosa plataforma para crear tus propios sistemas del #IoT con #Arduino#ESP8266 y #RaspberryPi Te ahorrará mucho mucho trabajo. También tienes el #podcast
Using #nodered , #MQTT and an @rtlsdrblog v3 dongle to pick up the 433Mhz transmitters in my fridge/freezer and plot / alert them. Here is the past weeks worth of data. You may ask why, but I had the gear and lost some food a while back to the old broken fridge. And it's so easy.
Finally made something useful out of @atc1441 s ESLs, his PriceTag AccessPoint and @bitluni s #NodeRed DHCP Decoder. The ePaper display will always show the IP of the last device connected to my network!
In the meantime the #arduino Pro portenta X8 is up and running. Since docker is pre-installed, I just typed a short command and now I have #nodered up and running. 5 minutes from when I turned it on :)
Un servicio único. Un servicio para gobernarlos. Un servicio para encontrarlos, un servicio para atraerlos a todos y atarlos en la nube. #NodeRED es el servicio que te permitirá comunicar #hardware y #software muy fácilmente #ESP8266#Arduino#RaspberryPi
