Hi rejoe2!

What kind of nrf24 do you use, and where did you buy these?
I think that you use capacitor as well, and stable 3.3V dont you?
Do you think that this shield is good for my node? It would be very good if i didnt have to use cables for nrf24....

Get some easy pcb instead or other similar solution 😀

I use nRF-Modules in the "normal" format and several pa+nla-Variants,. The first ones I probably bought from the ebay source mentionned on the mysensors-site (build-page), but by now, I may have used parts from around 4-5 different ebay-sellers as source. They look different, but until now, I only got "non-blob"-modules which all seemed to work reliably in the end. One time, I really was convinced to have bought fake and bad ones, but in the end it turned out these problems where mainly sw-related.

For powering, I initially used AMS1117-only-Modules and additional caps, but using the above adaptor-modules made things much easier, as they have all relevant parts on-board (3.3V+caps, space is no problem in my personal use-cases).

Fyi: As I now prefer wires over rf, I'm about to replace most of my nodes by RS485-variants.

Thanks for the suggestions.
Had you got problems with nrf24?
Tomorrow i will try to configure openhab. I have tried to find a quick up to date guide for openhab 2 + mqtt mysensors but font find one.
Mysensors said that their bindigs support only ethernet or serial gateway officially.
I dont understand what is the diff (or why mqtt used mostly) the ethernet and mqtt solution but i have started the mqtt already.

Best regards

I indeed had some troubles with nRF nodes, but related to this.
FHEM is used as a controller and two serial GW's, so: no experience with the MQTT stuff.

I see. I hope, i can use it for a while:).
I think im closed this topic. The solution was to change the nrf24 modules, because i could not pair them.
The anoother problem was that i use two power source, and i didnt common the GND.

Thank you everyone who helped to me!

Reading through your posts: am I right in assuming that these NRF24L01 are rubbish and I should buy some proper ones with a chip instead of a blob?

Or has anybody a pair of them up and running?

Thanks and best regards,

I havent had got blob one yet so i havent got experience with it. But i red about the blob version and it should work....
But I suggest to you that you should buy these from reliable brand/shop. I think Itead or keyestudio are reliable brands. And i bought a pair nrf24 from ebyte, but it hasnt arrived yet.

Yes, those are rubbish. I lost countless hours trying to get them working but without success

Ok, spent half the day trying to figure out what I was doing wrong and all I had to do was read the forum. The radios I purchase were junk. Not one of the 10 worked. Had everything placed on a board figured my workmanship was a little off or something. The radio was last to be checked.
WOOOOOOWWWWO

Thanks Everyone this post saved me a lot more time.
