I shall give that a try.
I have found one of the dongles IP address - just have to find the other
HI, many thanks for your fast reply. So along the lines of… turn off all grid charge slots on the inverter, set 24h grid charge time slot within the Lux integration and use automation timers to tell the inverter to turn on/off grid charge?
Hi. I do not have, but, it’s easy to create. I’m working currently on a new release, but, right after new release, I’ll work on a script to allow use battery voltage instead of SOC to control charge.
Yeah, it should work. I have automation to charge only night tariff and it works perfectly.
Absolute newbie here, pondering home assistant to try and solve a problem that my EV charger install has created.
I have a Luxpower hybrid inverter alongside circa 10kw of pylontech batteries. My EV charger has been installed in a manner that discharges my home batteries first, which is suboptal in my opinion. Option to have the whole system repaired has been discounted because of cost.
Is there any means within your integration to set the home batteries to ‘off’ whilst the car is charging? Current solution is to do this manually within the Luxpower app but I’d prefer to manage it automatically somehow.
Thanks in advance.
For my opinion, you have two options: use a Tuya or Sonoff clamp sensor on the L1 phase of your charging box and create an automation that switches the inverter to bypass mode if there’s current draw. Or you can connect it to the smartload output if your model has one.
I have LXP-LB inverter, in my inverter when it discharge does not matter if load is on LOAD ports or GRID ports (when grid is on), it uses the CT to detect the minimum power to discharge batteries. Then don’t appear that is a physical installation problem, but configuration that should be adjusted.
If you are charging EV when the inverter is discharging batteries the only way I see to don’t use batteries is stop discharging changing configuration of inverter.
I think that both available integrations can do the need changes on config to stop discharging if you already have how to known when you are charging the car. Just remember that there is no much information about the wear of parameter storage on inverters, then just dont make too frequent changes to have long life of your inverter.
Hi everyone,
I’m trying to connect my LuxPower LXP-SNA-12K inverter to Home Assistant using the luxpower-ha-integration.
Setup:
- Dongle: E-WiFi (v2.07)
- Inverter SN: 51730D****
- Dongle SN: DG********
- IP: 192.168.1.199, Port 8000 (open)
Issue:
The port is reachable (nc -vz and ping OK), but any Modbus request via modpoll, lxp-bridge, or the HA integration returns:
Connection reset by peer
or
Could not read inverter model
What I know so far:
- Firmware 3.x disables Modbus TCP.
- Mine is v2.07, which should still allow it — some users confirmed it works.
- In my case, port 8000 opens but immediately closes the session.
Question:
Has anyone with E-WiFi v2.07 successfully connected via Modbus TCP?
Is it possible this firmware also blocks plain Modbus or requires a downgrade?
Thanks in advance for any help or confirmation!

Your dongle shows as just “E-Wifi” on luxpower web interface ?
I have seen one case with user of 2.x firmware that shows “E-Wifi ENC” on luxpower web interface, and does not worked with integration.
After requested support to downgrade it appeared as just “E-Wifi” and started working.
I’m using 2.09 and dongle appear as “E-Wifi” and is working.
Hi Newbie here, just trying to integrate my LXP-3.6K Hybrid Hybrid inverter into HA, i have added the integration from HACS, and during setup after entering IP, serial numbers etc it says it has sucessfully connected.
I can see all the different entities for the inverter, battery, array etc in HA but everything just reads as unknown with no data being shown.
Any ideas?
Hi, I’m having trouble connecting my Luxpower GEN-LB-EU 6K to Home Assistant.
I’m using a dongle with a serial number starting with DG and firmware version 2.06.
When I try to set up the integration, I get the following error:
“Could not read inverter model. Please check the Host, Port, and Serial Numbers.”
When checking port 8000 with nc, it appears to be closed, although the device is pingable.
Is there anything I can do to resolve this? I’d really appreciate any help or suggestions on this issue.
I went through a similar frustrating process to others here. In the end I found (by logging into the dongle IP with a browser, then Network Setting) that the Local Port was set to 4346. Installed OK after changing to that
Hi,
I have a DG series E Wi-Fi ENC Firmware V2.07 but not working. I not found the original instructions about dongle, do you remember how to fix with downgrade or upgrade? Thanks
The cases that I have seen on a Telegram group the change was requested and the Luxpower Support changed something in their systems and dongle type changed from “E-WIFI ENC” to “E-WIFI” and started accepting connections on port 8000 without problem.
I suggest that you request this for the Luxpower Support in your region.
In my case when I tried to run nmap on my dongle they stopped accepting connections and was solved removing and reinserting on the inverter (don´t know if its a bug or any kind of safety of dongle). Maybe for the ones that dos not have “ENC” version and keep trying can reach this case also and the remove/insert can help.
In a similar boat, did you have to do anything more? I can also see from the dongle IP its using the port you mentioned but get the same issue when switching to use that
Probably a silly question… but is “Live Load” (Home Load) available as a sensor??? Everything else is looking great!! Using a LXP-3.6K Hybrid if that matters.
Also… is there any documentation available that explains the meaning of the all the sensors???
The entities are made from luxpower modbus documentation, which only have small descriptions that are mainly the entity name 
The entities behaviour and data depends of inverter firmware. Integration basically convert from inverter modbus to HA entities.
I contacted Luxpower technical support by phone, but they didn’t seem capable of solving the problem. I emailed them directly to China, explaining the situation in detail, and they also immediately dismissed me with the statement, “Your dongle doesn’t support the 10.10.10.1 portal.” So what? I spent money on an inverter that claimed to be an essential feature for me, and now, with a dongle, I find myself unable to read the values needed to manage my smart home. I tried unplugging and plugging the dongle several times, restarting the inverter, reconnecting to wifi but nothing worked.
you can follow the instruction in the github TThanhXuan/luxpower-DIY-dongle to create DIY dongle access direct the RS485 bus
I have two inverters in my setup.
I am able to connect to both of them but can’t seem to get the sensor/control info for both concurrently. Is this integration only supporting one inverter at a time?
Thanks for any info-guidance
