Thanks for the suggestions! I think I will first try the LED stripe way, it's probably the easiest for now.

@Fabien said in Receiving but !TSM:UPL:FAIL and no communication? 2.1.1 issue?:

In your gateway your don't #define MY_RFM69_FREQUENCY RF69_433MHZ . By default it sets to RF69_868MHZ

Oh my god! What an incredible stupid mistake!
I wasted all this time trying to get the NodeMCU to work only because I forgot that setting in my initial Wemos Sketch...
It's finally working now.. haha. Let me know when you're in Austria @Fabien you deserve a beer :)

@Johannes-Hodne thanks for the suggestion but it's finally working now :)

Thanks a lot for the clarification @mfalkvidd that helps!

Why based on nrf24? I came to the party late, but started with RFM69/433 - you are not bound to 2.4ghz in any way, it's just what people used to start with.

I'm using RFM69 yes, and it has no problems.
I don't need repeaters at the moment, as far as I know it's software based?

@Reza it depends on the use case I think, peope are using both, both are working. NRF24 is easier to set up and seems to have more support. Just try it :)

@mfalkvidd Thanks a lot for trying this out! I wondered if it is interpreted or used in a special way by the gateway already.
But in this case I can do that myself.

Thanks again!

Thanks for the explanation! I will now rather invest into more Mysensor nodes + RFM69 as it's simply more flexible.

@Nca78 the reason I'm also using mysensors on the temp nodes is that it allows me to use custom sensors (for these types mostly BME280/680).

@nca78 I'm still deciding what to use. Pro Mini if I don't find anything better.

I'm interested in where you buy your BME680 breakout boards, there are not so many around :)

I think I bought them here: http://www.watterott.com/de/BME680-Breakout
I'm located in Austria
