I do indeed have that - thanks man.

I get a connection established from my dev box to the VM hosting HA (it's a VM under Hyper-V running I assume ubuntu or some other flavour of linux). The IP address 172.25.163.148/20 was assigned by HA to itself on boot. E.g.

But yeah - good connection from the MQTT explorer to HA, so I'm inclined to think HA is setup correctly.

and that the problem is that my openDTU can't see the 172.25.163.148 address. Any way of doing a tracert or ping from the opernDTU client?

Aside: I did need to give it the username/password though that I setup for it in HA

And when you enter your HA details, do you see the SA sensors there too? Like so?

Also you did add the mqtt integration too right?

You need to reconfigure the VM so that the network interface is bridged to your main 192.168.0.0/24 network. I haven't used HyperV but Google informs me your looking for an external switch in HyperV parlance.

Thanks Jonathan. Yeah, I came to the same conclusion at the same time. For some reason when I created the VM for Home Assistant, it bound itself to a virtual NIC which I setup (ages ago) and that NIC would allow traffic from the guest OS to the host OS, but no routing. Hence why the MQTT explorer on my devbox hosting the HA VM could see it, but nothing outside of this pair could.

Correctly rebinding the VM to a virtual NIC off my actual network adapter in use and we're on the 192.168.0.xxx network. I knew it was that, just didn't know why! :-)

Next step is to see if I can get openDTU to talk to this new address, this should be an easier problem.

bullit_dodger

Boom - done! Look at that glorious screenshot :-)

Hasn't picked everything up yet, but I believe that's a matter of time. Or a little tweaking - possibly when the sun is up
Now the fun part is to get some charting/dashboards up and running. Pity it's dark outside as the inverters might be "offline" now, so that might be why not all 4 inverters are showing. I'll have a play around with it.

Thanks for your help everyone. boards.ie for the win.

When I enter my HA details where?

Ya, I added the mqtt integration.

This is what I see in Mqtt explorer.

Ha! And there was me assuming this was on docker. 😁

Don't forget to bind that IP so it doesn't jump if it's DHCP.

I hadn't specified one way or the other - so t'was a fair guess. Just see now that all 4 devices have reported in (along with the 5th device being the official Hoymiles DTU). No data of course as it's dark….but yeah, looks I'm good with the hardware on HA now. Anyone got any recommendations of dashboards that are worth a look?

I made my own using apexcharts and also use the default Energy dash in HA. Then stick in the solar forecasts and get nice projections.

I'm getting this error in the mqtt log.

New connection from 127.0.0.1:59038 on port 1883.
 Client <unknown> disconnected due to protocol error

What's the IP here? Is this HA or SA? This means SA mqtt is working I think

When you go to mqtt in HA, under integrations, who do you see?

Should be something like

And you created the mqtt config file like they say in the SA docs?

allinthehead

Ya, that's the SA IP.

Under integrations in HA mqtt has no devices or entities.

I have the code pasted in file editor.

I'm not sure I fully understand this line though-

• remote_username and remote_password should be uncommented if you configured MQTT authentication in SolarAssistant.

Log from mqtt

Looks like it's checking for a username and password, but not getting it.

Jonathan

@SD_DRACULA I don't have SA, but why wouldn't you just configure SA as a regular MQTT client rather than bridging the two MQTT servers?

SD_DRACULA

https://www.boards.ie/discussion/comment/121982895#Comment_121982895

Paste what you have inside your solar_assistant.conf file so we can compare to mine

Sounds to me you have your username/passwords enabled on one side but not the other

Also paste your mqtt config from SA, this one:

https://www.boards.ie/discussion/comment/121982914#Comment_121982914

Yeah not sure why they have it configured like that 🤷‍♂️ I was thinking the same when I was setting it up but got it working so never bothered.

They have a crap photo in their guide, the text has it in there but the photo does not:

Try adding it there and then restarting HA

allinthehead

https://www.boards.ie/discussion/comment/121983074#Comment_121983074

I had that in previously, and it still didn't work. I put it back in there now and restarted but no joy.

On the mqtt integration, what information should I be putting in the configuration?

This is what I have at the moment, everything else I try fails to connect.

SD_DRACULA

https://www.boards.ie/discussion/comment/121983143#Comment_121983143

Looks correct.

For me it detected it automatically on the integrations page.

Do restart SA as well just in case and you can also try to do a reload on the mqtt integration

allinthehead

Thanks, ya did all the restarts etc. Deleted mqtt and started again too. Just don't get it.

allinthehead

https://www.boards.ie/discussion/comment/121983168#Comment_121983168

In Mqtt options, did you need to make changes?

allinthehead

Started again, wiped all the changes and went to a previous back up.

When I just install the mosquitto broker and make no other changes, that error is there.

Glad you are up and running. Should power up early on as it doesn't take much to bring the micro inverter to life.

You could set up the standard energy flow card like 10-10-20 or play around with the gauge cards or the sunsynk flow card linked earlier.

I still fiddling and using all three at the minute until I'm happy.

bullit_dodger

Pretty impressed with HA. Amazing that this is free as it's an awesome product.

Struggling to get some of the layout the way I want it, and also an entity with daily total production (sum of the individual panels), but this is more me being a klep than a problem with HA ….

Hmm I'm not seeing the solar_assistant.conf file on your log:

So I think the mqtt addon is not configured correctly.

Your config looks like this?

This is the mqtt bridge way which you should not need.

Try from scratch and just follow this one: https://solar-assistant.io/help/home-assistant/setup

Add them up like this:

    sensors:
      solar_watt_total_sum:
        friendly_name: 'Solar W combined'
        value_template: "{{ (states('sensor.hm350_power') | float + states('sensor.hm700_power') | float + states('sensor.hm800_office_power') | float) | round(1) }}"
        unit_of_measurement: "W"
        
  - platform: template
    sensors:
      solar_energy_total_sum:
        friendly_name: 'Solar Total Energy - Sum'
        #entity_id:
        #  - sensor.hm350_yieldday
        #  - sensor.hm700_yieldday
        #  - sensor.hm800_office_yieldday
        value_template: "{{ (states('sensor.hm350_yieldday') | float + states('sensor.hm700_yieldday') | float + states('sensor.hm800_office_yieldday') | float)|round(1) }}"

What I'm saying is that I wiped everything and installed mosquitto broker only. Didn't do anything else and it shows that error in the log.

allinthehead

This is the log when I follow the instructions.

Still looks to me it's trying to do the bridge setup, maybe go to mqtt on SA and add a username/password

And then update the conf file with the username/password you just created in SA, something like:

connection SolarAssistant

remote_username someusername
remote_password somepassword

address 192.168.0.154

topic # in

topic solar_assistant/# out

SA is defo working correctly, just a matter of getting it right in HA

Thanks for sticking with me on this.👍

Already tried adding a username and password, unfortunately no change.
