General Discussion

I have a CVD ZnSe (Chemical Vapor Deposited Zinc Selenide) lens I'm planning to experiment with in this kind of use case. It should work in theory. It bought it for my IR camera, but I've understood it's commonly used in laser cutters.

Thanks @korttoma , that's what I was hoping to hear.

It's me again, sorry that I bother you. I found problem so I just copy definition RF24_PA_LEVEL instead of MY_RF24_PA_LEVEL regards,

@sundberg84 As far as I understand by looking at the code you have sensor on the same node which is requesting the pulse count from the GW?? OR you have reed switch on this node and sensor is on some other node? In the debug prints do you see a READ message in the serial monitor for your node which has reed switch? With me, I am sending the request() from node 1 to node 2. I can see SEND message in serial monitor of node 1 and READ message in the serial monitor of GW and also a SEND message in GW serial monitor and READ message in node 2. So the message is reaching node 2 successfully but my node 2 is not sending any reply to that message. So, node 1 is sending to GW, GW is receiving it and sending it to node 2, node 2 is receiving the message but node 2 is not replying. Is this what is supposed to happen? OR node 2 is actually supposed to send a reply back to node 1?

so my 1 message a second is literally like nothing as far as the mysensors RF protocol is concerned. Shouldn't impact at all?

@Spanners what hek means, the channel ID is set compile time. So before uploading to your node. So putting it in before() is currently not an option. What you can do is putting the RF_BASE_RADIO_ID define in a separated include file (.h) and include this file before the other defines in all the sketches. So you only have to update the ID once for all your sketches.

It might be possible to put nodered between the gateways and your controller to aggregate the gateways. I don't know how to do that though.

@mfalkvidd, when you download the library 2.0 and you extract this. There is a folder documentation which is almost empty. But in the meantime I found also a link api on the download location with more info. The sketch did work! Great! Based on this example I can going forward.

:thumbsup: sounds good. The processing power and memory would allow for a (basic) controller functionality.

@NeverDie sounds like mysensors is not your cup of tea then.

@AWI Thanks for the piece of code. Now i can see where i was wrong! Let me run it... this seems to be missing the interrupt part though. I will try using DV on Int2...

hello. Yes you can. I advice you to read this great guide for more infos : https://www.mysensors.org/about/signing

Discussion continued at https://forum.mysensors.org/topic/5080/the-basics-of-mysensors-continued/ (couldn't figure out how to fork such a long discussion into just one topic, the forum software doesn't seem to handle that. Sorry.)

@marex after sleeping I think I understand your question. Start by writing nothing in the setup, presentation and loop. Just use the examples as they are, following the instructions on the links I have already posted. That will get you a working gateway and working temperature nodes. You can then add your own code for handling communication with your phone, or just use one of the available controllers which will handle that communication as well. With MySensors it really is that simple. Note: I am moving this discussion to a separate thread, since it really has nothing to do with the MySensors 2.0 release.

Hi @aishwarya7 Welcome to the MySensors community! I am not familar with the attiny13, but from the datasheet it looks like it has too little flash and sram to run MySensors. Instructions on how to upload sketches to an Arduino is available at https://www.mysensors.org/about/arduino#uploading-example-sketches See the buying guide for information on which components are recommended when getting started.

They do look nice, but it seems that they have a standardized icon / layout, that can't be changed. I would like to have the possibility to display arbitrary information on my dashboard / scene controller, so I'm creating a webpage mimicking a "weatherstation type display", and plan on using a cheap wall mounted tablet for the interface. this will also make any updates to functionality on the scene controller easy, as it's just a website that needs updating. preliminary proof of concept is at https://juletraesfoden.dk/t2/app. Backend is a mix of domoticz / node-red / python webservices..
