why on earth anyone would dislike this video, I really don't get it. the video quality is splendid, voice is crystal clear (which is usually reasons for getting thumbs down), instructor got into topic quickly without killing any time or advertising any lame product. He dint even ask for subscribe/like/paypal me/donate. I found him humorous too. Godddd!! Internet really is a dark place.

now i think of it, may be a competitive channel owner disliked the video, even then its a cheap thing to do.

Comes with territory I think. Perhaps someone didn't find all the answers in the video... I focus on actual comments and feedback left.. as good feedback is welcome and valid criticism is also helpful to understand how others see my video and channel. Thanks for your kind words Manjunath

I’m grateful to see such an elaboration. Hats off to your knowledge and presentation skill. Undoubtedly I’m newbie into this, and exploring all I can, may be you could point me to the right place, if there’s a guide to get expertise over nodered. I’m still unable to correlate some basic stuff sometimes...my first project I’ve decided is to have complete dashboard for my room lighting controls. I’ve already bought one Nodemcu.v9 and got raspberry pi able to use gpio pins. But not over wireless MQTT.....please advise me. Thanks in advance.

I have a couple of projects that involve the dashboard so feel free to browse the website. But if you have any specific questions Im happy to answer or point you in the right direction

While watching your most excellent videos I began to ponder the possibility of using Node-Red in the Windows environment. Can you have Node-Red search your computer for files containing certain text? I am thinking Node-Red could easily do this I am wrong? Oh and one constructive point....use zoom, please.

Nodered has an exec node which can do anything command line can. Also read and write operation for nodes should have some extra info about the file structure

Tasker is only for android devices ,what about people who work with IOS devices is there any alternative? and also is there any alternative for IFTT because it is not free

Unfortunately not. Tasker is one of the reasons I stick with Android

How can we write RESTful API's in Node-RED which fetches data from MongoDB with some specific query instructions and bind it to the dashboard? Thanks in advance.

How can we convert string output into json data...
@notenoughtech
@notenoughtech 5 жыл бұрын
Assuming that your string has a valid JSON structure, you can use JSON node with setting "Convert between JSON string and Object" - this will return the proper JSON object accessible via msg.xxx.xxx format

@@IoTLearner This IS JSON formatted string - the only issue would be the 32145 is saved as a string instead of int. Please connect the debug node, set it to object mode and pass the entire object here - i will give you more details about it.
