A great integration. Works fine with one V2 battery! Unfortunately, I can't get the other 2 V2s to work. They have a different slave address (unit ID). Is it possible to specify the slave address during installation (just like with the Marstek Venus Modbus from ViperRMNC), so that I can get the other 2 working as well?
Thanks in advance!!
Hi,
There are users that have connected Venus E v3 batteries to a Elfin EW11A adapter. You could give that a try.
Best regards
Hi,
Can you explain more about your setup? Are you using one adapter for everything? I had two Venus E v2 with two Elfin EW11 adapters and worked with no problem.
Best regards
I have two questions - here is my setup:
I use an IR Reader for my Power Meter.
The Current_Energy Sensor is used as Grid consumption sensor
1.) I had issues that discharge and charge was not set automatically. I had to set the working mode to manual - however - the Marstek App doesn't show it as manual. Is that normal?
2.) The integration shows unballanced cells (0,174mv). I have read you post on github. This morning charging started as expect - slow and keeps current_energy at 0. However - when starting active balancing charging switches to maximum charging. Is that expected behavior?
Best regards...
Hi,
That is not normal. Please open an issue in github so I can keep track of that. Attach logs and snapshots of your setup so I can further troubleshoot this.
Thanks
I opened issue on github - however - I am not sure where to find the logs.
The 3 Marstek V2s are connected to the LAN network via a PUSR-DR134 using the RS485 TCP protocol, each with its own unit ID.
This works very well with the Marstek-Venus-Modbus integration by ViperRMNC. I have created a few energy automations, but yours are much more extensive and sophisticated.
Hi Funes, I have your Marstek Venus Energy Manager running, working great.
The 2nd battery I added keep dropping out ever so many days, showing as non-responsive.
Both batteries are Venus E v3.0, first one running V1.48, second one V1.47.
Where do you suggest to start looking for the reason of the non-responsive issue after a few days of correct operation?
If the manual mode is set to charging, then surely only the excess solar energy should charge the battery, and not a set value like '2000 watts'. The Net zero (only charge) option should then be variable, looking at self-consumption and generated energy, and the Marstek should adjust its charging capacity accordingly. Currently, you can only set this to manual with a fixed value.
Hi,
The integration isn't designed to be used that way. In fact, there are other integrations out there specifically built to work alongside Marstek's native modes.
The 'Work Mode' in this integration is only there as a backup for emergencies if ever needed, but it is not how the application is meant to be operated. This integration features its own built-in PD controller, which is designed to take full control of the battery without any interference from Marstek’s native settings.
Best regards
What integration version are you running?
I'm running version 1.8.4
Hi, I can't get this to work... I'm trying to integrat my Venus D into HA but no matter what I do it won't work. I tried the Local API integration but it fails to connect, no device found. Now I tried this one but when I install it, it asks for Sensord that I just don't have. This HA stuff is so confusing I'm sorry I don't understand what I need to do!?
I have a Venud D and a ct002 both connected to my wifi and the Marstek APP, everything works fine but HS refuses to work or I just don't understand how it's done... I tried for hours but nothing seems to work... Can you help me?
Hi,
Local API is not supported. Also CT002 can't be added to HA as far as I am aware, you will need another grid sensor like a shelly or a homewizard p1 in order to use this integration.
Best regards
I'm using an emulator AstraMeter (b2500-meter) for my Venus C with the marstek modbus integration. The emulator has an option to talk to ct002/ct003.
Hi,
Does astrameter allows you to integrate a physical CT002 in HA? I thought that integration was used to emulate any meter so the Marstek app could find it.
Best regards
Sorry for the confusion, it uses a sensor in home assistant to emulate a ct002 or a shelly energy meter.
Hi,
I have included this functionality on v2.0.0b2 version, can you please test it out and let me know if it works for you?
Best regards
Oh ok, so how can I get it to work?
The CT002 is connected to the Venus D, I managed to find another integration that uses Local API and I was able to connect my Venus D into HA. You don't need to connect to the CT002 directly, you'll get all data from the CT through the Venus D Local API.
Hi,
That connection method is not supported by the integration. You will need a separate power meter in order to use this software.
Best regards
