Hello!! And thank you again ......
A really good job, it's something that was definitely missing ......
I would suggest to the directors to expand the guide on OTA you better explain the steps to change channels and make a link to your great job !!

Now if I understand this and the Bootloader that I have to load on my Arduino Pro-Mini, in practice insert in the path of the IDE of Arduino when I make the updates use that channel

As soon as I can I try them and I'll let you know, in a lot of thanks again ......

@sindrome73 Hi Good evening, and I'm sorry for the delay in the reply.
As you have never done a Bootloader, if you are kind enough to do it, I thank you.
The channel I'm using is the "Channel 84" for now I'm using only the 16MHZ Bootloade, but if you want, the others are fine too.
In addition you can give me some starting point to be able to fill in too ??
Thanks for your availability, greetings

@guillermo-schimmel Thanks for the reply.
Very useful, but can you tell me more accurately what software to use to recompile after making the change ????
Maybe some links to the software to download ..... thanks again for the availability

@mfalkvidd Hello.
From what I read it is possible to somehow modify the channel for OTA updates, this is also said here.
https://www.mysensors.org/about/fota

But I can not find other info on how to proceed to change the channel .....
Can you give me some other clarification or link to follow ???

this is a good place to start and start to understand.
I'm not a lot of diggers, however I start reading something, and in case I'll ask for help
In a lot of thanks

@kimot I did not understand what you tell me, can you explain better or with some examples ??

Hello
So if I understand, a node from domoticz can only ask the status of a sensor connected already him, and not the status of other nodes of the network!
So it is impossible for me to create nodes / displays to display the status of other sensors in the network.
The only way is to use some old mobile phone as a display point

do you mean that it is not possible to request those data from the node that will make the display ??

@pjr
yes, I intend to receive data from devices that do not belong to that node, but to other nodes.
So random devices of the network

Hello!!
I would like to make some small displays to put in the house where you can see the status of some lights and temperatures.
So it was my intention to retrieve this info from Domoticz from time to time. If I understand correctly I should use the "request" command only that I have no idea where to start ....
Has anyone already done something like this and wants to share their experience and / or a piece of code already done ??
