Whats the options for a solis hybrid inverter with the latest dongle to get data into home assistant?

Solis api/cloud integration or the Solis modbus which drops the cloud piece unless you do the local rs485 work around.

The cloud one now offers the inverter control which works well.

Yeah, got an esp32 all set up and working well with the Seplos BMS, gives me a good enough view of what is going on with the Seplos and the WECO's now.

As for the Shelly, flashed it with Tamasto then tried flashing ESP32 ota but currently won't upload from HA to the device although it is pingable, tried flashing it through usb but ended up distroying the board so thats work in progress.

Guys, looking for help.

I got hold of a Huawei R4850G2, I have the power adaptor and CAN adaptor and have it set up and working..ish.

I can vary the voltage no problem but all I can get it to output amps wise is 5A.

Below are the "frames" I have been sending to it, voltage changes work fine.

I can0 108180FE [8] 01 00 00 00 00 00 E9 16 58.1V not fixed

can0 108180FE [8] 01 04 00 00 00 00 C7 38 50 Amp fixed (1020)

I have downloaded the USBCAN software, which seems to work fine. (not sure what everything means or does?)

Found a lot of info online about the Huawei rectifiers but what ever way I am doing it the output current stays fixed.

I know its only 5amp as I have it temporarily connected to just the Seplos battery and the BMS studio is showing the current going in.

I have a few bits ordered ESP32 and VP230 so am hoping to integrate it into HA which again hopefully will make it easier to view and make changes.

Any pointers as to what I am doing wrong currently would be appreciated.

Thanks

Guys, HA question, adding another Dell Wyse in another location, should I build a fresh HA install and add the integrations, addons etc or could I use a back up from an existing install and just remove the bits I don't need, change the static IP and ducknds? Also does anyone know if you can run integrations on both HA install at same time ie Solis (API) Tyua etc, or would it depend on the integration? Thanks

Another location and new instance of HA to monitor the same devices, or is this an instance for another location and different sensors entirely?

Bit of both, essentially I want to be able to monitor a Seplos battery hanging off a Solis in an apartment, I figured it was easier and probably no dearer to buy the Dell (£25) then use an ESP32 running the BLE battery management integration then trying to get remote access to the ESP32 (I know it can be done) but the video on YouTube was an hour and a half with god knows how many twists and turns the HA route seemed a lot simpler. (Apart from the last 5 days trying to get HA on the Wyse 3040) but thats another story.

Ok… still not entirely sure what you're up to, but essentially if you restore the instance onto a new HA then it will start looking to connect to each of your devices to pull the status. In my case it would not work for my z-wave or zigbee devices as the second instance wouldn't have access to the USB dongles, but also Shelly devices as they need to be configured with a single endpoint server (no option for two).

So I'd say to just go with a new fresh instance from scratch.

Yeah, I think you are right as I don't have any where near as much memory on this one so the less "stuff" is on it the better. Thanks
