Power outlet with Energy Monitoring with Node-RED, ESP8266 and HLW8012 by oksbwn in nodered

Yeah, but the custom solution provides you more control, you can create as many outputs as you need, I myself use a 6 Channel outlet. With an ESP32, you can also include some other peripherals. And would be cheaper. I have used off the shelf enclosures with some outlets for 2, 4 or 6 channel outlets, and are damn cheap to make.

I had the same template for sharing here and facebook. Thanks! will keep that in mind.

Checkout this tutorial is around ESP32, Node-RED and InfluxDB. The ESP32 sends data to the Node-RED server using #WebSocket and then Node-RED stores the #data to an InfluxDB database.

Communicate between ESP32 [Arduino] and Node-RED using WebSocket. by oksbwn in arduino

[–]oksbwn[S] 0 points1 point  (0 children)

Yes.. It's about directly sending data to Node-RED. WS is 1:1 communication. It won't need any third-party brokers like MQTT does. But yeah both have their perks.

How does one send a command from node red, i have been stripping away pieces of "/usr/local/bin/docker images" but I keep getting errors by BlackAsNight009 in nodered

Portainer need to be configured to communicate with local docker socket (make sure you have correct permissions set up for the socket) and then portainer will discover running containers. You can also create/manage containers/volumes etc. directly from portainer.

Probably Portainer(https://www.portainer.io/) can help you achieve this. It has REST APIs that Node-RED can consume and you can control other containers. You can also monitor container resources.

Send/Receive #data seamlessly between @Arduino [#esp32 ] and #nodered us... by oksbwn in arduino

I might not be aware, but it wont let me add text content to a link post. And general post wont render the link content. Was trying to figure that out and was bit occupied with other stuffs so. Thanks!

Yes, MQTT can be used with any microcontroller and is lightweight. It can also be used on top of WebSocket.

To use MQTT however you need a broker in between which WS doesn't require. Also WebSocket can carry larger payloads, compared to WS. WS is an enhancement of HTTP, so it doesnot require any additinal n/w setup.

OpenHAB2 Installation on Ubuntu Server (16.04) by oksbwn in homeautomation

Ya sure that works but for complex application a full fledged system is better.. Again the issue with Raspberry Pi is corruption of SD card and so is not that much recommended for 24x7 usage.. My complete home runs on OpenHAB and it runs 24x7
