Solar PV Monitoring/Automation Thread

Since you have the registers now you can create/modify registers list and start sending data to mqtt/hass or if want fancy dashboards prometheus/grafana.

Thanks, will check it

It is difficult to figure out which inverters/wifi sticks these apply. I see hybrid listed but the register do not match what I have at the moment.

Never mind the page says that different model have different maps. Also looks like RHI series in US have different map to the ones in EU. Not sure I understand the logic why Solis try to over complicating this.

I do no think the documents that floating around are the official ones.

I haven't looked at the document provided by @Jonathan yet but wanted to share this one that Solis sent me today.

Great work @Jonathan /@reklamos with the solis stuff.

Still trying to find some time to see if @Jonathan 's code can be made to run via node-red, the readings from the solis server are unreliable and have skewed the data a few times in HA for me and had to manually edit them.

I have node-red currently set up to pull all data from solis server and then send to mqtt.

Had no luck in the past in getting python to run via node-red, do share if you ever get it working 😁

Yeah could probably do that but I rather not add one extra device like Pi to just run this, node-red runs on my HA instance so getting to run there would be perfect.

I know it can be done but a bit beyond my skills.

Nice to see both of you got it running.

Ahh nice one mate. The way that I've been doing is via the REST API and I grab the data via a bit of powershell.

# Set system variables
$baseUri = "https://www.givenergy.cloud/GivManage/api/"
$json_extration_folder = "C:\Tools\GivEnergy\Cloud_Extract\"
$filename_Datetime = get-date -format "yyyyMMdd_HHmm"
$Inverter_date = get-date -format "yyyy-MM-dd"

#---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# Login to GivEnergy Cloud and create a session. 
#---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
$loginUri = $baseUri + "login"
$authMode = "Windows"
$tokenRequestBody =
@{
  "account" = "xxxxxx"
  "password" = "xxxxxx"
}
$output_filename = $json_extration_folder + "Login_response_"+ $filename_Datetime + ".json"
$login_response = Invoke-RestMethod -Method POST -Uri $loginUri -Body $tokenRequestBody -SessionVariable "MySession" 

#---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# Download the Inverter API information
#---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

# Get the getInverterRuntime
$loginUri = $baseUri + "inverter/getInverterRuntime"
$tokenRequestBody =
@{
  "serialNum" = "xxxxxx"
}
$output_filename = $json_extration_folder + "InverterRuntime_"+ $filename_Datetime + ".json"
$getInverterRuntime = Invoke-RestMethod -Method POST -Uri $loginUri -Body $tokenRequestBody -Websession $MySession -Outfile $output_filename

and then it returns a JSON file, which I then dump into a FoxPro database (old skool me) and I can slice/dice it at will. I don't have a "proper" JSON deserializer, so I had to write my own.

With the GET api's I can modify the charge setting, timings to charge/discharge etc. although I'm not doing any of that at the moment. One of my pet projects which this is leading me to is interrogate the Met Eireann API and then figure out a "expected" generation for the next day and figure out the battery charge level.

In theory like a few others I could do a few things with smart plugs - but idea in the infancy with me at the mo.
