What is/are your question(s)?

i have a mebay generator controller and i have the modbus registers but i dont know how to get it working with genmon
can someone please help me with this, i have include modbus manual

Hi @yellowdre

This wiki article has the process for adding support for new generator controller.

There are 4 steps described in the above link. If have provide number 1, if you can provide number 2, I can add support my completing number 3.

In short you need to connect a pi to your controller via the serial interface. I assume this is RS-485? is that correct? Once you do that you can use the modbusdump.py program to read the registers. I will use the register data provided via modbusdump.py along with the data in the attached PDF above to complete step 3.

Let me know if you have questions on how to proceed.

I have added support for mebay DC4x - DC9x controllers. I have only tested with registers from a DC42 so let me know how testing goes. any feedback is welcome. Submitting your registers and logs from the about page helps me track down issues so if you do try this please send the feedback.

I move the issue thread here to this thread.

The wiki page has been updated.

@maindrive
if you are testing this let me know how it goes. Also, if you have a bulleted list of any steps you are taking to set this up on the generator controller side please send them to me and I can create a wiki page for the MEBAY controller. pics and / or screen shots are great.

Also any info on what things you did on the genmon side (e.g. RS-485 adapter, cable, etc) would help also.

I can make the wiki if you just give me the data.

Let me know how your testing goes.

I also renamed the json file that you sent in the other thread so you will need to update the software from the About page, then set the controller on the advanced settings. Also, the frequency, RPM, rated kw, will be set on the Settings page, not in the JSON file so there is no need to edit that.

[jgyates]

I contacted Mebay and they sent over modbus docs for more controllers so I will look at this tomorrow to see how many can be supported.

Woo Hoo!, That's great news..
Please change the E Stop from 1 and change to 0.
The current time (Holding:1008) keeps flashing red.
Yes, I will send a write up of what all I have done.
The biggest hang up was the CRC check setting, it must be changed to ***** CRC:L-H ***** in the RS485 Port settings in the controller.
My Controller Default is CRC:H-L

Again Big Thanks For Your Support!

on the registers live view page in the genmon web interface, if a register changes it turns red and then it will become a lighter red over time. If the register changes again then it will go back to the darker red. This happening for registers that change, like the time, is expected.

I checked in an update that changes the polarity of the emergency stop bit.

Let me know what else you find.

Hello Jason, I have included my MEBAY_DC42D_MK3_With_Commands.txt, the command are working, but the Engine State : Alarms do not print out under the Engine State. Engine State statuses work fine, I would expect when in alarm the alarm statuses would be printed like: Crank failure, Emergency stop, RPM Signal lost, some where on the page? I have tested: "2": "Under speed", "19": "RPM Signal lost", "46": "Emergency stop", "47": "Crank failure", // Here is what I have tested. Please find attached zip file with pics The main stumbling block need to set 485 CRC Setting to CRC:L_H in the rs485 communication port setting in the controller Tested with the following: #Pi Zero 2 setup https://www.waveshare.com/rs485-can-hat.htm RS485 CAN HAT for Raspberry Pi RS485 CAN HAT #Add driver sudo nano /boot/config.txt or /boot/firmware/config.txt sudo nano /boot/firmware/config.txt dtparam=spi=on dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000 This creates /dev/serial0 -> /dev/ttyAMA0 commands used to test sudo ./genenv/bin/python3 ./OtherApps/modbusdump.py -r 19200 -p /dev/ttyAMA0 -a 10 -s 4096 -e 4191 sudo ./genenv/bin/python3 ./OtherApps/modbusdump.py -r 19200 -p /dev/serial0 -a 10 -s 4096 -e 4191 #Raspberry Pi 4 setup https://www.waveshare.com/rs485-rs232-hat.htm Isolated RS485 RS232 Expansion HAT for Raspberry Pi, SPI Control RS485 RS232 HAT #Add driver sudo nano /boot/config.txt or /boot/firmware/config.txt sudo nano /boot/firmware/config.txt dtoverlay=sc16is752-spi1,int_pin=24 This creates /dev/ttySC0 rs485 port and /dev/ttySC1 RS232 port command used to test sudo ./genenv/bin/python3 ./OtherApps/modbusdump.py -r 19200 -p /dev/ttySC0 -a 10 -s 4096 -e 4191 # for Laptop or Raspberry Pi DTECH USB to RS422 RS485 Serial Port Converter Adapter Cable port settings Baud: 19200, Data bits: 8, Party: None, Stop bits: 1, Flow control: none Raspberry pi command used to test sudo ./genenv/bin/python3 ./OtherApps/modbusdump.py -r 19200 -p /dev/ttyUSB0 -a 10 -s 4096 -e 4191 # Network Note: The PUSR USR-W610 and Waveshare RS232/485 TO WIFI ETH setup web pages look the same!

Thanks for the update. It looks like you attachement was removed by github. If you respond to the thread in email, github will remove the attachment. You can either post the attachment via the github web interface or sent it to my email address. I will incorporate these changes into the projects and make a wiki page for the mebay controller with the data you provided.

The active alarms and warnings are suppose to print in the status page under the heading active alarms. This is done via the "alarm_status" and "alarm_conditions" objects in the JSON file. If alarm_status is true, then it will display alarm_conditions. You should also get a notification via email or add on (email gives more info) if an alarm is active.

Also, if you have email setup and fucntional can you submit your log files and registers on the about page? Submit them on an active alarm if possible.

[jgyates]

I have updated the repository with the latest JSON file and I created a wiki entry with your screenshots and data. Thanks!

When you get a moment it would be helpful to submit your log files on the About page. Outbound email must be enabled for this to work.

I got your logs. It looks like you are still using the old file JSON name for the custom controller

This should be changed on the advanced settings page by selecting MEBAY_DCxx.json and then deleting the file file /home/pi/genmon/data/controller/MEBAY_DC42D_MK3_Comands.json

If you do not make this change then future updates will not take effect until you edit your old json file. If you use the newly named file then you will get updates just by updating from the about page.

Other than that there are no unusual things in the log.

I made the corrections you mentioned. Let me know if there are any issues. Also, you should see a setting for Nominal Battery Voltage on the settings page so make sure that is correct (12 or 24 V). This sets the max and scale of the battery voltage gauge on the main web interface page.

There were some issues with the default values if the JSON file specified "Unknown" that were causing the problem you mentioned. If the JSON file specifies "Unknown" then it should use the genmon settings and since the Mebay custom controller JSON could be used on any generator I have made it default to the settings of genmon which are user configurable.

Let me know if you have any other issues.
