@dpressle This is an impressive unit!

I love the neatness and non SMT. Fantastic.

Do you have an idea of the pricing all up?

[dpressle]

Thanks, should be under 10USD in parts.
BTW, same design but for roller shutter is on the way

Hello,

nice design with some care for safety !
If possible, I would suggest to connect A4/A5 to the connector, so it would be possible to use (for example) an i2c touchpad, to command the 3 relays and more, for example mpr121 can manage a mix of touchpads and leds. In case of managing leds, of course a Vcc connector would be necessary too as the last input pins would not provide enough current.
Analog pins A0-A5 can be used as digital pins if needed so it could still work as you designed it at the moment with physical switches.

On thing that is annoying me also with some designs, is that when you want to use in ceiling to connect directly to ligh bulbs, you need to use connectors/wago to "duplicate" neutral because the board only provides live. If possible you should move J1 to the right, and put holes to add extra 2x connector on the left if people want to have neutral without external connectors, it will give a much cleaner result when connected instead of a mess of wires. I think it's possible to do it if you move the varistor to the left, and change orientation of F2.

@Nca78 Thanks for the tips, i understand what you are saying about the neutral and it is a good idea, my intentions were to put it in the switch box and not in the light fixture itself, but i might add it to the next release.

@dpressle nice!

@breimann Thanks, does any one want link to dirtypcbs?

Hi, dpressle. Thanks for your work?
One Question. Can i connect a normal light switch to it? So that i can turn on the lights with the switch and this node?

[dpressle]

@artipi Sure you can that is the whole point of the D5, D6, D7 connection.

You just need to take the GND and each of these digital inputs and connect them to the switch (NO high voltage in the switch only GND and digital input), each one of then controls one relay.

Thanks!

Where can you find the code?

[dpressle]

@MLs Its in the OpenHardware page see the Source Code tab:
OpenHardware

Note its intended to work with "Home Assistant" HA, some depending on your controller some changes might be needed.

@dpressle

Ok tanks

Do you have a bootloader with OTA enable

//Mattias

[dpressle]

@MLs Yes sure

[MLs]

@dpressle

Can you email it to me or maybe add it to your project.

//Mattias

[dpressle]

@MLs I am using the one from here link text

[MLs]

@dpressle

Does the bootloader use the internal 8 MHz clock?

//Mattias

[dpressle]

@MLs yes it does.
