Re: Any chance of gaining control capabilities over Modbus?
That has been done as a HA add-on. You can check it out here https://github.com/nathanmarlor/foxess_em

Re: Home Assistant + Grafana
Also using Grafana.
Can you post your json configs for the dash? I'd like to improve my own.

Re: MeterRS485 Comms Ports...
Can't comment on RS485, but on CT vs Modbus meter the CT wins. Reaction to changes in phase conditions is much faster from what I can tell as the sampling rate is higher. Normally I would prefer to use an Eastron (I have on in circuit) over CT but having switched to the FoxESS platform my mind has c...

Re: Battery Balancing
Quick update, Modbus TCP -> RTU has now been implemented and works with the standard HA setup as a USR-W610. If someone wants to test a prototype let me know.

Re: The ethernet port no longer works from firmware version 1.50
Ethernet ports are vulnerable by their mere availability. Having embedded controllers available on a network is always a problem, communications on ethernet uses up valuable resources on the tiny Arm Cortex MCUs that runs the entire inverter. Mess with that port and you can bring the whole lot down,...

Re: FoxESS V1 BMS protocol
V2 is a knowledge void for me. I can only demonstrate what I know based on how my own kit presents (fw < 1.50). There are two communication buses at play here, master to inverter and master to slaves. I do not have any information on the latter. I'm happy to look at the V2 in detail but I need can t...

FoxESS V1 BMS protocol
Users who wish to decode the can bus messages sent between the BMS and inverter can find a suitable dbc file here: https://github.com/rand12345/solax_can_bus/tree/dbc_codegen When used in conjunction with a can bus sniffer (SavvyCan), this file will decode each can message into human-readable values...

Re: Battery Balancing
Quick update.
I have the LilyGo CAN485 running with dual can bus. Pretty nice unit.
Edit: Some screenshots from Home Assistant from BMS can comms (MQTT)

Re: Battery Balancing
Yes, it will be the exact same data but with a ~2 second refresh rate. I can knock some basic PoC up once the boards arrive. Can bus will be set to listen only so it’s a pretty safe system that should not require the BMS cables to be unplugged. I have an assumption that BMS and Com share the same ca...

Re: Battery Balancing
If Python is your thing I should be able to give you some PoC code for monitoring the raw values coming out of the BMS (Com) which can be pushed to MQTT (HA hosted Mosquitto) or modbus TCP. It will help with local rapid data measurements of charge rates, high and low cell volts, temps, etc Hardware ...

Re: Hi from Lancashire - new PV / FOX ESS
Could you describe the problem in a bit more detail? Screenshots or photos could help if it's data related.
Looks like the NW is well represented here, quite a few of us now!

Re: Potential ESP32 comms interface
Appols for the late reply, didn't enable notifications! As I see it, the operation of such a device would be transparent as the primary goal would be to map the RTU registers to TCP. Configuring the HA integration would be a matter of setting it up as per the TCP template. There may be one or two di...

Potential ESP32 comms interface
Hi StealthChesnut Reaching out on here regarding this post on your HA repo https://github.com/StealthChesnut/HA-FoxESS-Modbus/discussions/50#discussioncomment-4818239 Would you be interested in a collaborative project to develop a custom interface? There appears to be quite a few V2 issues that can ...

Re: Fox Hardware board.
Will, Would you consider a dedicated topic to can bus communications? This would bridge both battery (agnostic) and inverter and may suit its own section. The reason for the request is to reach out to other techs and devs who would be interested in patching many of the new V2 issues that have been r...
