Hi. I am using the node below: [image] node-red-contrib-ds18b20-sensor Node-red node to connect DS18B20 sensors The problem is, I need to control a relay with a button on the screen, but for now, I am using an LED to see if it works or not. When I click on it, i…

I switched to this one: [image] node-red-contrib-sensor-ds18b20 Node-RED node to get temperature in centigrades from DS18B20 sensors It greatly reduced the delay for the switch.

I see that it prints out all 4 at the same time mostly, sometimes the 3rd one is one second late, and the 4th one is 2 seconds late, compared to 1st and 2nd one. Button works fine for some time, then it happens again. I think in that 10 second timestamp, 4 second is for sensor to read, 6 seconds are…

Is there anything I can use as an "interrupt"?

Did you wait for the button stopped working? Does the node output stay the same at that point?

Node output stays the same. It shows 4 values as expected, then I can freely change the swtich state. When it is time for the sensor node to do its thing again, I am unable to change the switch state. I press it, and it happens after the sensor node is done doing its thing.

Ok, that confirms that the node is locking up node-red while it is doing its scan. I think that the idea in this node of doing a complete scan of the bus may be what is causing the problem. I suggest that instead of telling it to scan everything that you use it in the mode where you pass in a devi…

Something like this [{"id":"49bf5a26.718594","type":"inject","z":"57017347.8029cc","name":"Every 10 secs","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"10","crontab":"","once":true,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":250,"y":480,"wires":[["47b77a6c.0bf7f4…

I put it before the sensor node, now it doesn't switch to the 2nd page. I also got "Connection Lost" error. Edit: It switched to the 2nd screen and now it is working even slower. It refreshes itself from time to time.

What are you seeing from the 1-wire node now? I presume that you did set up the topics correctly, I had only put the first one in.

It should switch in 2 seconds to the 2nd screen, but it takes like 10 or even more seconds to do that in the editor side, and it stays the same for even a longer period of time on the UI page.Also, it gives 4 of them at the same time like previous version. Edit: It didn't even switch to the 2nd scr…

I couldn't understand it. Can you please explain it in a bit more detail?

How can I send 4 objects, and how can I do it again and again? I have the IDs in the switch, I just couldn't understand how to implement your idea on Node-Red.
