Very good project ! Will do you sort an nrf smd version?

[TD22057]

Very cool. Would you mind adding a pdf of the schematic?

[Achim]

Very nice box for a lot of Projects. Can you please post the buying source,

[Sander Teunissen]

@Koresh
I see so much beautiful stuff coming by. Are you planning on selling this as assemblies like you did with the stable node ?

Sander.

@TD22057 I have exported images from the source files. You can see them here : http://www.photorapide.com/albums/tonnerre33/cemrki/mini-relay-box-by-koresh.html ;)

Unfortunately I can't open my ebay shop right now. While I'm trying to open it, you can buy this board here: https://www.ebid.net/eu/for-sale/arduino-ide-compatible-220v-10a-switching-relay-with-433-mhz-radio-onboard-156694880.htm

I forgot to upload the photo of the completed device :smile:

can i order a 868mhz version? it seems perfect for my home project that is already running 868mhz and if it is working i would order many of them.

[Koresh]

@Nicola-Muratori thanks for your attention to this project. Yes, I have 433, 868 and 915mhz modules. So I can produce this board with any module. Just write down in PM what quantity you need.

@Koresh ,@yury
Will you also make a nrf version like you did with the wall insertable switch node?

Thanks,
Sefi

[gohan]

How do you calculate power? Do you have also a voltage measurement in addition to the current sensor?

Or maybe we should use the nrf2rfm69 board you are creating?

[gohan]

@Sefi-Ninio for that case it could be an idea to have a second pcb design with nrf24 smd footprint, it should be too difficult. Otherwise it will be a good chance to start using the rfm69, that is not a bad idea 😀

Yes, rmf69 is great. Though most gateway instructions are for the nrf, and me being the newbie I am, I need clear instructions 😬

Is it still possible to get this with different freq radio?

[shabba]

Ah! I found it on your shop. Thx.

Hi Koresh,

I ordered a Mini Relay Box and a Wall Switch Insertable Node and use the two sketches you have provided. Can you help me getting the direct switch node-to- node signing working. I have everything installed, personalised the nodes (AES, HMAC) and loaded the sketches. The messages between the gateway, switch node , the relay node are working perfectly without message signing.

When I turn on message signing the messages between gateway - switch node and gateway - relay node are signed and verified correctly. However the switch node does not sign the messages for the relay node. I have tried to add a signerPresentation() to the presentation section of the relay node. Unfortunately this did not provide the solution.

Do you perhaps have a sketch for the relay and / or switch node that features the signing of direct node-to-node messages?
Regards, Marcel

Please specify what type of transformer you are using.

Hi @koresh - I had a little accident on the AC side :-). I was wondering what values the 2 resistors (TH and SMD) and diode are ? Thanks!
