Hey guys, fantastic video! Really appreciate. Continue doing node red videos 👏

[timnaylor]

right at 24 min you were asking if you can have multiple entities, the answer is yes in that entitiy_Id field you can enter ["id1", "id2", "id3"] and it will act on all of the entities in that list. I do something similar with a flow that changes colors through several lights and my function node changes the colors of the 3 groups, and then sends to 1 call service node that has all the lights that should be the same color (just as if it were a group, as Travis had suggested).

an other: if you drag some nodes on a flow page, you can connect one to each other without moving from input to output, but while just pressing CTRL when you click the 1st little ball on 1st node, and keep CTRL pressed you'll get an other wire ready to connect to next node :)

Late to the party but this video made me interested in trying node red!

[sabineundmichaelhornung]

Thanks for this video. This helps me a lot!

I believe you mentioned that some nodes in Node Red don't need Home Assistant. The only nodes that DO need Home Assistant will be Home-Assistant-related nodes. NR is not tied to Home Assistant at all and I've never used the latter. NR is a stand-alone environment that can work with a variety of conol systems and packages. It is possibly the best thing to happen to home control and its at the very centre of my own home control endeavours which hardware-wise uses a Raspberry Pi 3b+ to run NR and far more besides. In the past I've done this with Orange Pi, FriendlyArm boards and others. On the control side I use ESP8266 pruducts including Sonoff, our own boards and various others from Urope, China, the USA and UK.

Ok, I would say the following, wouldn't I... a very popular node for Node-Red is Node-Red-Contrib-Bigtimer .. he says with humility. I use Node-Red, talking to various devices via the MQTT Nodes and using both Node-Red Dashboard and Blynk to interface with the devices via mobile phone. Big Timer is again central to operations and I use dozens of them in my two-location (UK, Spain) installation. I've encouraged many clients to go down this route, successfully.

[squalazzo]

other trick: CTRL-click on the flow page, you'll get an ADD NODE facility, you just start typing the node name and you can easily add them without scrolling the left column :)

[squalazzo]

at 1:07:00 about saving some nodes as templates, here's an other one: if you select one or more nodes, then press ctrl-c, then go in the top right menu (where's the palette), go to EXPORT, LIBRARY, add a name... whenever you'll need these nodes again, just go in IMPORT, LIBRARY and select your saved snippet :)

[squalazzo]

hey doc, if you double click on a FLOW TAB, you can disable a full flow alltogether, so you can still have it there, but deactivated, in case you need it in the future again

Hi Doc,

I have watched the replay and found the information extremely helpful.


I hope you will be able to help me with this one!

I was able to set up my Sonoff to trigger my AC (Around 45:00 of your vid) and I would like to limit the power "on" of my aircon to only working hours (perhaps add 30minutes on both sides)
so I added Bigtimer as it seemed like the ideal engine to use for setting time to validate against.

My question now is: HOW do I combine that time restriction with the temperature trigger I managed to setup?


Kind Regards

Frits

[Gaatech]

Big timer is very cool and i have alex able to issue the auto setting within bigtimer

[squalazzo]

an other one: if you drag a node which has an input and output "little balls" (like the change, switch, function, range, etc, ones) onto the connecting wire of 2 existing nodes, the wires automaGically reconnect themselves to arrange the new node connection :)

Little clarification around Hass.io, the Node-RED addon and its authentication:
The add-on DOES NOT USE long-lived access tokens. Instead, the add-on cycles its tokens every time the add-on starts. This enhances security over long-lived access tokens.

[IkkeVanAdel]

@DrZzs I can't get this to work. The log says it connects to the websocket, I can see all my lights but when I click the toggle (eject) I get an API error. The log says.
28 Dec 12:36:33 - [warn] [api-call-service:Switch buro] Error calling service, home assistant api error
28 Dec 12:36:33 - [error] [api-call-service:Switch buro] Error calling service, home assistant api error

I want to learn how we can live stream the tweets from twitter on specific topic using red node.

[georgelza]

Can you post a link to the videos you mentioned of Travis, that you watched before making this, thanks

[gregmacausland]

Great stream on Node Red! Looking forward to messing around with it this weekend!

[ukaszZalewskiLooker]

Hi guys. Is any tutorial how to run a Hass.io on usb memory stick on Raspberry Pi?

[jayare]

Can Tasmota be flashed to an ESP-01S (1MB)? If so, what would be the best approach? Total noob here

[LOUISIS]

SOLVED!!!

Awesome video man love all of your vids I've just recently got into node red and tried to install the dash button node but failed with error I searched around and added to the config to install libpcap-dev the log shows it installed fine but still can't install the node using hass.io any advice would be greatly appreciated
