You should be fine even with a cheap multi-meter as long as it has uA scale.

should be around 7-10 uA and if you do not send JDEC to sleep it is 17 -19 uA.

to send JDEC to sleep\wakeup I use
_flash.wakeup();
_flash.sleep();

light sensor should be sent to sleep explicitly also.

Right - but this is all in your sketch right? This is what I used:

@Koresh would it be possible to sell this without the sensor part and RFM69? How many orders would it need?
I don't have the possibility to produce it myself, don't need the sensors part and have a lot of RFM69s lying around..

Thank you,
Christoph

I downloaded gerber files.
Error Message from PCB Manufacturer:
The NC drill layer does not match with the pads of copper layer.

Thank you,
Attila

@anovak
Hello. Do you mean main board or rfm69 adapter? It is very strange. I produced exactly these gerbers many time. :thinking_face:

[Koresh]

Finally I have a little time to continue this project...
High efficient dc-dc converter works nice and double cr2032 are good. Lets go to the furher tests! :face_with_cowboy_hat:

[anovak]

Thanks. The problem was solved.
Manufactured at very low cost on pcbway, they are manufactured with "Min Track / Spacing: 5 / 5mil".
Do you have any idea where they are manufactured cheaper?

[Koresh]

New version with double battery holder and power convertor works nice.
Power consumption in sleep mode is less than 9uA :smiley:

I will test it soon..

[alexsh1]

@koresh You only have two sensors BH1750 and Si7021. Did you try to have all four sensors and measure consumption?

[anovak]

Which pcb manufacturer do you recommend?
I asked for a quote from Pcbway but it was expensive.
The reason was:
Change the 'Min Track / Spacing' value from 6 / 6mil to 5 / 5mil.

Sorry for my bad English.

[Koresh]

@anovak Unfortunately you can reduce the price of the board only if you order more boards.

[anovak]

What price can be made in 10 items?

[gohan]

@anovak if you mean 10K maybe you can have a discount :sweat_smile:

[anovak]

10 would be needed for the current project
At pcbway, the total cost of production and shipping costs is $ 34.
Is there someone who does it at a lower price?
Business account required.

I apologize for asking this question in this topic.
What type of transformer do you use and where to get it for the Mini Relay Box?

[Omemanti]

@anovak do you want them completely assembled?

Yesterday I ordered 2 plain PCB's from seeedstudios, cost me 20 dollars incl, shipping. paid more for shipping than for the PCB's themselves. :)

but for the size, these units are you can get 6 or more in one design.

[anovak]

Only PCBs are needed.

[Koresh]

@anovak I use in mini relay box the same transormer as in wall switch insertable node. Please read this comment https://forum.mysensors.org/topic/3938/wall-socket-insertable-node/57

[A Former User]

Can we buy it fully assembled and what would it cost?

[yury]

@kenci

Yes, in a week or so. Even with plastic enclosure ))

[A Former User]

@yury what would the price be for the fully assembled board?

[yury]

@kenci

EUR 18 the board with SI7021 and BH1750. extra 1EUR for enclosure if someone need it.
