Hey @yury , thanks for the reply!
The pictures were very helpful :)

Does this board come flashed with the alternate bootloader that supports OTA updates?

Hello friends,

Reading the instructions for building a RaspberryPi Gateway using RFM69, it states that one should use the development branch and not master, since the Pi is using a different version of the driver.

Anyone knows when this will be merged to master branch?

Also, since this forces all nodes to use development branch as well to be able to communicate with the gateway, assuming I use the development branch now and it is later on merged into master, is there an easy way to upgrade nodes remotely to the new code?

I am planning to use Wall Switch Insertable Node, and Mini Relay Mode - Both support OTA updates, am I correct to assume this will allow upgrading without taking the nodes out of where they are located?

Thanks!
Sefi

@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 😬

@Sefi-Ninio said in 💬 Mini Relay Box:

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

Thanks,
Sefi

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

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

Hello @yury and @Koresh ,

I am not sure how to connect the switch in the wall to this board.
My house has Gewiss switches, but J1-J4 expects 2 wires - so I am not sure how they connect... Can you help?

Thanks!

This looks great! Thanks a lot @dbemowsk !

Hi @hek ,

thanks for your answer. Unfortunately, this will not work for this application...

Will that work as a weight sensor?
Couldn't understand from the description nor could I find the data sheet...

@Yveaux Perfect, thanks!

Hi!

Say I want to create a node that turns everything off when I fall asleep.
One option would be to use a heart rate / pulse sensor and when it goes below a certain amount, run the turn off action - but that will require me to wear the sensor.
Another (less accurate option) would be to know when I lay down on the bed, and after a certain predefined time - run the turn off action.

Another scenario is that I want to know when there's new mail in the mailbox.

For this - I need a weight sensor node that can sense the weight change of the mattress or that there's new mail on the sensor in the mailbox.

I can't, however, find such a sensor. All I can find is a pressure sensor which seems to be barometric + temperature sensor...

Anyone knows of a weight sensor I can use for this node?

Thanks!

Is that related to the circuit for battery level? Or something else?
What are the differences between the current rev. and what you are working on now?

@Samuel235 Any news regarding the new revision?

@aproxx will the second relay be opt-in?
I mean, will the board function normally with only one relay?

@aproxx great news! This is something I look forward to!

SMD is easier with solder paste and hot air solder

Even though it's untested, would you mind publishing the Gerber and bom files?

Looking good!
I see you went with the SMD path! did it allow for a smaller PCB?
Don't see how you handle the creepage though.

Like the picture here shows :

Hi @sundberg84,
I was talking with a friend of mine who has pcb design experience about your board, and he told me to tell you that it would be better to add creapage protection between the 220v and the 5v sections, by bigger distance at also a longated gap. He told me the term, but I can't remember it now...
