💬 Button size radionode with sensors swarm extension

[Cliff Karlsson]

was it possible to buy this board assembled from you?

[Koresh]

@Cliff-Karlsson The local factory starts assembly today (button size node, insertable switch node, wall socket insertable node and mini relay box). ETA is one-two week (max).
This board is avaliable with two radios - rfm69hw and rfm69cw (with adapter shown below). Price will be the same. Which radio is preferred for you? If you plan to use this board with battery I suggest to use rfm69cw module to extend battery life (it has lower but enouogh power and works down to ~2V).

@Koresh said in 💬 Button size radionode with sensors swarm extension:

rfm69cw

yes rfm69cw is fine, as I understand it will still be compatible with rfm69(H)W gateway?. Also are you using 868 MHz band or any other?

I don't remember where I read the prices, could you give them again? And can you buy the atmega/rfm -board separate from the sensorboard or do I have to buy them as a set?

[gohan]

Will it be available preassembled? :)

[Koresh]

@gohan Yes. Of course :smile:

[Koresh]

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-coincell-powered-controller-rfm69cw-hcw-433-mhz-radio-156694991.htm

[gohan]

Best of luck for your shop :+1:

[bjornhallberg]

Great! One question though, is everything already soldered and if so is there an option to for 868MHz?

[gohan]

@bjornhallberg if you want you can just order pcb and build your own node

[bjornhallberg]

@gohan Yeah I could but I'm just too lazy :-) There are a lot of components to source from AliExpress before anyone can build these boards. It would take months even if there aren't any errors in the BOM or lost packages from China.

[gohan]

@bjornhallberg since @Koresh is still in the early production stage, I think he can manage to make a few with a different radio, given of course he has the 866 mhz modules available 😁

[bjornhallberg]

@gohan Thankfully I do have some CW 868 radios (~5 left) available that I bought ahead of time. I think everyone can solder the radio to the board by hand and so I personally would prefer that @Koresh would consider selling the parts separately.

[Cliff Karlsson]

If possible I would also like the option to chose 868 Mhz or be able to buy board without radio.

@bjornhallberg
I have some assembled boards without the radio. You can buy them here https://www.ebid.net/eu/for-sale/arduino-ide-compatible-coincell-powered-controller-ready-for-rfm69cw-hcw-radio-156711327.htm . I just reminding this board has a rfm69HCW footprint but you can solder rfm69CW modules with the pcb adapter which I made. Of course I will supply the adapter with the main board.

[bjornhallberg]

@Koresh Thanks! Great solution with the adapter board as well, you really do think of everything. Do you have the other boards without radio as well? Specifically the Switch Controller?

[Koresh]

@bjornhallberg
I have some insertable switch boards without radio. I planned to solder nrf24 into them but can sell them without radio too (it supports only cw modules). Will put up for sale soon.

[bjornhallberg]

@Koresh Sounds great! Oh and btw, any idea how customs will handle the packages, any chance of taxes and customs fees? You're outside of the EU customs union right?

[Koresh]

@bjornhallberg I do not know exactly, but I don't think there should be any fees. Try to find out tomorrow.

[alexsh1]

@Koresh I got one of boards and would like to add Si1132-A10-GMR. What else I need to add? C8?
Why are you not using this sensor on your board?

[Koresh]

@alexsh1 yes, you should solder the sensor and the bypass capacitor. I have a lot of si1132 sensors, but I can't find the correct library. Almost promo videos of commertial sensors based on the si1132 shows incorrect data ))) It shows correct UV and IR level, but incorrect visible light value. So I decided to not solder this sensor yet.
