@gryzli133 Sorry but i dont know how to debug Domoticz

@gryzli133 Its tested and working on Homeassistant, you will probably will have to modify the code to make it work with other controllers, let me know if you need help with that.

@hummeruli
for #1 try switching also these variables:
#define DIRECTION_DOWN 1
#define DIRECTION_UP 0

for #2 can you send debug output?

@hummeruli can you check "Show verbose output during: " for compilation in the Preferences page and send me the detailed compilation log?

@hummeruli It compiles just fine on my machine, what version of mysensors do you have? i am using v2:

@hummeruli its here:

@gryzli133 No, Sorry. Let us know if you make it happen.

@gryzli133 The only way i can see is using the radio pins 9, 10, 11, 12, 13 if they can be used with RS485 or i2c then you are good to go

@Lucien Sorry for the delay, i will post it soon.

I just wrap it with wet toilet paper, works every time.

@Boots33 Thanks, looks very nice, antenna is a little big but very interesting.

For another project i am working on i am looking for a way to be able to transmit data to a specific direction (not 360 deg) for few hundred meters 100-500 (one way).
I would love to use the nrf transmitter if possible but any idea will be greatly appreciated.

Thanks.

Small update, i connected touch switches to the board instead of mechanical switches.
where i live we are using gwiss switches and when the board is in the box there is not much room for mechanical switches as they are too deep, so i took some blanks that are used to cover unused switch hols and added touch switch to it, see the pictures below:

@Shaun-Storbakken It was designed with the idea of controlling 3 different loads of up to 2 Amp each, lightning, switches etc.
The D-5,6,7 are for manual switching and they will (if you use my code) control the 3 relays respectively, J1 is power input 110-220V, please note that you should pay attention to the polarity and connect line wire to the right of J1 (otherwise you will end up switching natural to the load), J2 is AC output where each one is different relay, so you have 3 X 110-220V outputs of max 2 A each.

I hope it was helpful, please let me know if you need further help.

@Eawo Here you go

@MLs i use what you use, Mysbotloader 1.3pre, as i said in one of the first messages, you dont need me to send it to you you can (and did) download it from here.

This is why i think you are doing something wrong or have wrong settings.

@MLs You said before "The problem is not to burn bootloader."
and now you are saying "No if I'm burning 8MHz Mysbootloader, the Atmega circuit does not start."

I am asking again, are you able to successfully burn and run Mysbootloader 8Mhz or not?

@MLs I am completely lost here, you said "I do not get Atmel to run with Mysbootloader 8MHz." and now you are asking "how to know how a bootloader uses an external clock or internal clock" how can you say its not working and then ask me how to know that its working?

To conclude this, if you successfully burn the 8Mhz Mysbootloader and the board is working then it is working with 8Mhz it cannot be working on 16Mhz because there is no external osc, its not 1Mhz because of the fuses etc.

@MLs try to first upload the burning sketch to the nano (even if its already uploaded) and then burn the bootloader.
What set up do you have, how the nano is connected to the atmega?
What error do you get when bootloader burn fails?

@MLs as i said, i can only try to help if you get me more information about your environment and pictures and then i can compare it to mine.
