Support for the Resol VBUS protocol?

[bbqkees]

Likely yes.

have you tried any other sketch that sends data to the serial port so you know that works anyway?

[Wass1]

No I haven't can you enlighten me about this feature ?? what kind of sketch ??

[Wass1]

Hello
Finaly i am getting data from my circuit the problem was the cable connecting my resol regulator to the circuit , everything is working fine now... but if you don't mind me asking do you have any idea on how to store this data on a SD card ??

[Bernoo]

Hello,
i have a Resol BX controller and a VBUS to USB adapter and i would like to display the temperatures with domoticz. did anyone else do this before? I do not know how.

Hi.

I have build the vbus sensor and connected it to arduino mega that is using a wiznet w5100.
On serial console i can see that my setup is workin OK, i get the values from my DeltaSol C 0x4212 heres a debug info:

---------------
Destination: 10
Source: 4212
Protocol Version: 1
Command: 100
Framecount: 7
Checksum: 3
---------------
---------------
Now decoding for DeltaSol C 0x4212
---------------
------Decoded VBus data------
Destination: 10
Source: 4212
Protocol Version: 1
Command: 100
Framecount: 7
Checksum: 3
------Values------
Sensor 1: 24.30
Sensor 2: 35.70
Sensor 3: 50.40
Sensor 4: 0.00
Relay 1: 0
Relay 2: 0
0
------END------

My problem is that i cant get any data to be display in my domoticz server.
I can ping the mega on my network but no data on my domoticz server.

Can anyone help me out on this problem
This is the ethernet shield i have on my mega:



And here's the link to protoboard i have build:

First make sure that you have chosen a proper IP address and a unique mac address.
Then make sure both the Arduino and the machine running Domoticz are on the same subnet (so f.i. 192.168.1.x).

If there two devices with the same IP address then it won't work.

A good next step would be to modify the sketch such that it only sends a dummy httpRequestTemp(IDX, value) so you know that works as well.

Dear programers
I have built my own dattaloger for vbus resol, using the vbus library, it worked fine with the Resol DeltaSol C4 and Resol DeltaSol BS , but using the same code and library for the Resol Delta Sol E generated many errors , and i can't seem to figure out why any suggestions ??

[Wass1]

Help please i m still getting the same error values any suggestions ??

[bramv]

I didn't want to connect an Arduino to my Resol SLT because it already has a LAN interface.

This is how I connected my Resol device to Domoticz by using vbus over lan with Node Red and MQTT.
It should work with other vbus devices as well


1) install Resol library from https://github.com/danielwippermann/resol-vbus
npm install --save resol-vbus

2)
git clone https://github.com/danielwippermann/resol-vbus.git
cd resol-vbus
npm install

3) install /compile json live data server
See: https://github.com/danielwippermann/res ... ata-server
cd /resol-vbus/examples/json-live-data-server
copy config.js.example to config.js
nano config.js

Change your ip and password
<code>
/*! resol-vbus | Copyright (c) 2013-2018, Daniel Wippermann | MIT license */
'use strict';



var path = require('path');

var config = {

/**
* The port number for the HTTP server to listen to.
* @type {Number}
*/
httpPort: 3333,

/**
* The inteval in milliseconds between two writes of the logging file.
* @type {Number}
*/
loggingInterval: 10000,

/**
* The filename of the logging file.
* @type {String}
*/
loggingFilename: path.resolve(__dirname, 'live-data.json'),

/**
* The name of the `Connection` subclass to use for connecting to the VBus.
* @type {String}
*/
connectionClassName: 'TcpConnection',

connectionOptions: {
/**
* The host name / IP address of the VBus/LAN or Datalogger device.
* @type {String}
*/
host: '192.168.178.41',

/**
* The password for the VBus/LAN or Datalogger device.
* @type {String}
*/
password: 'vbus',
},

};
</code>



4) Check if web server works
Start live data server:
sudo node resol-vbus/examples/json-live-data-server/index.js


Open page in browser: http://192.168.178.32:3333/api/v1/live-data/

Should look like
<code>
[
{
"id": "00_0010_1001_10_0100_000_4_0",
"name": "System date",
"rawValue": 564698061
},
{
"id": "00_0010_1001_10_0100_004_2_0",
"name": "Temperature sensor 1",
"rawValue": 12
},
{
"id": "00_0010_1001_10_0100_006_2_0",
"name": "Temperature sensor 2",
"rawValue": 23
},
etc.
</code>

6) Automatic start up the live data server

crontab -e
add following line

@reboot sudo node resol-vbus/examples/json-live-data-server/index.js

7)
Add couple of dummy/virtual devices.
I used 5 temperature, one counter device for the PWM pump and one switch for the heating assistant valve
The idx's of these sensors must be used later.

8) Import in Node red

9) Change Node red to your environment
a) Change node “http request” to match your IP
b) Change the node “FilterVBUSSensors” if you have different sensors. Use list of sensors from step 4
c) Change the node “IdentifySensor” to match the idx of your dummy/virtual sensors of Domoticz

[lucaspr]

I saw this thread and it is old, but I'm struggling getting things to work.

Now I get this error in my debug screen.

node: FilterVBUSSensorsfunction : (error)
'TypeError: Cannot read property 'substr' of undefined'.

Do you have any idea?

[Joost996me]

See my previous post. With the formatter from Daniel Wippermann I can get the data from my Resol KM2 every 5 minutes into Domoticz. This can be faster if you want it.
Thanks also to Dannybloe for his support with the dzVents script



A floorplan of my Solarboiler / Heating system. Combined with values form Atag One and Weather Underground.

Exactly what I am searching. Got the CSV on my pi but need a script to import it in Domoticz. Can you please share the script?

[javalin]

Hi Bbqkees I have followed your guide to build the vbus to UART and load the sketch in Arduino compatible Mega (ATmega) + Ethernet Shield, everything works perfectly with my Deltasol CS Plus controller . Great work!, but I can't leave a network cable from the technical zone where I have the solar controller to link the router because is so far, I know that I can connect a Vonets to transmit via WiFi but I thought that maybe the ATmega could be connected to an ESP8266 to transmit via WiFi, you know if it would be possible?

Kind regards

Thank you McMelloW, you use a vbus to lan adapter in your example?. I would like to send the data via wifi from arduino to domoticz without ethernet cable.

Thank you McMelloW, you use a vbus to lan adapter in your example?. I would like to send the data via wifi from arduino to domoticz without ethernet cable.

Sorry I have no experience with wifi and a KM2.
With the wget command I simply take a copy of the KM2 memory and this is stored in a file called current_packets.vbus.
Daniel Wippermann is a software designer, study the things he placed on github about vbus.

The formatter is used to change the contents to a json-file.

At the moment I have the sketch reading 4 sensor values form Resol controller. You need to compile one firm to Mega and another for ESP8266. The first read values from Vbus to UART converter and second sent data wireless to Domoticz via HTTP GET requests

[gratin]

Hi,

Would it be possible not only to read but also to interact with the Resol relays ?
i have a DeltaSol BX plus + a Datalogger DL3.

Thanks,
P.

Do you have any "extra" board, that want to sell?

I still have not made them yet, no time.
If you would order the components from Aliexpress/Ebay etc and buy a small breadboard it is not that hard to put it together.

The schematic is quite simple:

In your description you mentioned you removed the voltage divider. Which resistors did you remove ? I've tried to make the circuit on a breadboard and I've messed something up and it isn't getting any data.

Could you please post a high res photo of your breadboard so I can see what I've done wrong ? I'm not the best at reading circuit diagrams, but I thought I did it right...

You dont need the voltage divider with arduino UNO or MEGA, dont need to reduce voltage input. Didn't work for me also at first time.

Check wirings at breadboard and pinout to the arduino must match with your script.

For the Arduino you can use 5V but remove the 20k resistor at the end end and you can replace the 10k resistor above that with a 4,7k resistor but that 10k can also work.
Earlier this year I made a batch of PCB's for this but I never actually tried one out, I'm still using my breadboard version
