Looks like the same problem as previously?
You have used CR LF in the encoding string instead of character literals \\r\\n.

Not using Open API, but this may be of interest: https://github.com/assembly12/Foxess-T- ... ware-setup

No, I have not heard of anyone doing this.

The most common problem when creating a signature is that the special characters are converted before the string is encoded but the string values are literals. This especially may be the case if the string is passed through multiple stages of processing.

That is the string being encoded must ...

Have a look at the Open API documentation here: https://www.foxesscloud.com/public/i18n/en/OpenApiDocument.html#get20device20real-time20data0a3ca20id3dget20device20real-time20data4303e203ca3e

The real time data query is a post so does not have URL parameters. You need to post a body with the serial ...

What BMS firmware do you have?

We've noted that charge current is more restricted from firmware 1.014: this is case the max charge currrent is restricted to 15A below 20C (lowest cell temperature) and 10A below 15C. This was raised with Fox but I don't know if they have done anything about it yet ...

Charging via Open API for inverters that support setting Max SoC via a schedule is broken at the moment and will return Write Failure.

Hopefully, when Fox updates Open API, they will also fix this. More info here: https://github.com/TonyM1958/FoxESS-Cloud/wiki/Fox-App-v2#problems-setting-schedules ...

The error is service unavailable and is being seen by everyone right now.

The assumption is that Fox are doing some work...

There's a lot of stuff wrong with the Open API data from the point of view of PV generation and you can't get the Production data as shown in the Fox Apps. As it happens, the Fox Production data is wrong as well when you are looking at the Day figures. You have to look at the Month figures by Day to ...

Hi Chris,

Pending the update of Nathan's code, the code I'm currently running for my H1 inverter is here: https://github.com/TonyM1958/HA-Foxess-Modbus

The readme page gives info on setting up the RS485 connection, how to setup HA and selecting the modbus profile for your H3 inverter.

You will ...

Hi Tony, can I ask regarding inverter efficiency power out / power in does this take into account DC charging of the battery because my inverter efficiency looks very low?

Thanks, Chris


Yes it should - how low is your efficiency showing and did you pick up all the sensors correctly, as there ...

Following a discussion, here are a couple of statistics sensors that create rolling averages to remove some of the noise from the raw values.
The last 2 sensors convert inverter power in / out to kWh. These are used in the inverter efficiency calculation above.

Note on the templates above. I renamed some of the entities so they work with both USB and LAN connections and for consistency with Nathan Marlor. The sensor name changes I made are:

1. Remove dash from PV1-Voltage, PV1-Current, PV1-Power, PV2-Voltage, PV2-Current, PV2-Power, Battery-SoC, Battery ...

I've added some templates to my configuration.yaml to calculate various things I wanted to track / display. In case this is useful to anyone here, this is what I added:



#Templates enable math operations against states/values to give us better data

Looking at this, its hard to work out if there are new values here, so I've captured my HA dashboard (connected via RS485) and taken screen shots of the 30000 and 31000 LAN registers at about the same time:

For example, RS485 is reporting BMS ...

Probing my H1-6.0-E inverter at modbus address 30000 and finding a bank of 24 registers with values like this:


modbus LAN 30000.jpg


This thread is intended to look at these values and to try and work out what they might be.

Thanks to @eben smit, @bob dopper on FB who found these whilst ...

I've seen various references to modpoll (which is great for cross paltform) but wanted something a bit more graphical. Found this tool useful for poking around the modbus data via either LAN or RS485. This screen shot is showing data pulled from my inverter using the LAN with the inverter at 192.168 ...

Came across this diagram in the Fox AIO installation guide, using internal switch mode:


bonding.jpg


Clearly shows direct bonding of EPS N to grid N (no switch). This avoids EPS floating and generating a signficant N-E potential.

Also shows EPS E not connected. I checked this and EPS E is ...

I was finding that the inverter ethernet port was switching off after a while. It seems there is a problem with DHCP so you may need to use a static IP address for the port to work. It took a while to work out exactly how to do this, so here's a step by step guide for anyone else.

First, go to your ...
