Damn i keep on losing it at the bits and bytes parts. Hard to understand what exactly is happening with the bus data. O sniffed the data raw and the bus is putting out strings like 08 00 15 00. That part I can understand. But then... I have to put some debugging options in the code so I can see what ...

Did you make any progress rewriting the library to the new serial library? @others. I seem to have a problem with getting info on bbqkees register 10 should be hot water but value keeps getting a negative value. Strange. BTW decided to use just a mega and a esp8266 for the Wi-Fi part on serial2 ...

Yes Icon, you are totally right. I should have corrected this code in my Arduino but not updated it in Github, sorry for that. I am not using Domoticz currently, but just in case it inspires somebody, this is the web interface that I have developped in order to control the boiler. http://i.imgur ...

Damn that looks nice. What's your current setup now (hardware/software). Still the same ems bus circuit and an arduino? I presume you also do the writing part to the ems bus?

Could you post your code and updated library please??? I'm looking into it to make it work on UNO, getting there but not yet. Also trying on Micro which has a UART and a serial monitor separately. Found out the nefitserial library is based on arduino hardwareserial below version 1.06, so this helps ...

As far as I know you need an UART for connecting to the EMS bus. That means a hardware serial port. The EMS bus is somewhere a little tricky. As far as I know the hardware port on the UNO is also connected to the USB. (please correct me when I'm wrong) I'm now using a Leonardo where the EMS bus is ...

It seems the problem is in the library. On a atmega8 it seems to work but not on a atmega328p. So the library has to be rewritten.

i just like to see which information is available, from there i will decide which i will log to my domoticz setup. It seems that your code gets more info than bbqkees's code. For now I'm not using the TX part. I like to read only. Your code uses Serial3 i presume??? Yes, i use Serial3 to ...

Maybe softwareserial is a possibility. BTW I'm using a uno with integrated wifi from arduino.org. Should be possible I think to use the softwareserial for the EMS bus and the rest normal for making it work.

Is it possible to transplant the alterations in the serial library to the projects code. I think due to the alternated library my ciao library or unowifidev library doesn't work properly. If I send a ciao.write command with a normal code it updates my values in my domoticz setup. But when I put that ...

Can't relate the addresses in bbqkees code with the wiki bus addresses only 0x08

Can you make a quick alternation to your code so it doesn't use wifly. The code seems to stop now due to no connection

I have an arduino uno wifi from arduino.org so it's a clone with integrated esp8266 chip for wifi. It uses also a wifi serial console so I can use that for debugging. I'm going to look if I can change your code for usage with my uno board. Would be a pain in the ass. But will try. Maybe take out ...

After some effort I have the read function working. I wonder if you could share the code you are using for the write part. Hi Icon. Yes, I am preparing a GitHub Project with this code. I hope I will finish it during the weekend. I will post a lik. In this repository I have uploaded my code. https ...

Someone who can give me a Rs-Online stock number for the 4,7mH inductor, i can't seem to find the right one. So now i have all the parts but the inductors (will it work without them???) I found it with one simple Google search. These will do if you do not power the circuit from the bus: http://nl ...

Anyone have it working on a rpi yet? I like to connect all this to my RPI so i don't need an arduino anymore, i read i need a voltage divider to make it 3V3 (10k/20k). But i still have some questions. RIght now i have my smartmeter (electricity/gas) connected to my Rx/Tx of my RPI, so i think i can ...
