SauRoN's SomeWatt Solar Install

Home Assistant with Victron and Sunsynk

I think its time we had a Home Assistant thread here. I'll start - I setup the steaming heap of poop that is home assistant (yet again), and configured with some stats earlier this evening. This was after ditzing about for hours on Sunday with different versions of HA - 64bit, 8rc2, 7.x...

I used HACS for reading my Sunsynk to HA and from the Victron side, I wrote my own battery driver.

I pull locally via HomeAssistant over wifi.
Can be done though, on the Sunsynk RS485 (via RJ45) Pin 7 is A, Pin 8 is B

How do you do it over WiFi?

With Solarman? Or the new Sunsynk dongle?

I was planning to use the integration you linked previously but it all seemed very cable only.

Using Solarman you can use a HA integration to bring yhe data in. You can also get the Solar Assistant and that also allows data into HA over WiFi

I'm not sure how the Sunsynk dongle would connect into HA

I don’t think it can. I’ve portscanned it and nothing is open for anything to talk to it except Port 80 with a config page. It’s expecting to be able to reach SunSynks servers where it seems to just send all data and sync config changes. Unless there’s an api on that port I’m missing…

My setup is very similar to yours .

Older dongle. Read my link, i talk about it.

Have you done this ? I thought the Synsynk uses 4 wire Rs485 not 2wire? I pull locally via HomeAssistant over wifi. Can be done though, on the Sunsynk RS485 (via RJ45) Pin 7 is A, Pin 8 is B

The plugin I used is https://github.com/StephanJoubert/home_assistant_solarman

Works fine connects over wifi to the ip of your Sunsyk serial to wifi adaptor, and pulls data straight off that.
I have the older adaptor though.
 
Yeah seems with the newer adaptor it’s cable all the way.

Not really a problem as I’m running Ethernet to it anyway, will just run a second one.

Was just making sure there’s no way with the Sunsynk Dongle to go direct.

If you're really going to pull more data, probably makes sense to put a Pi there and connect that up.

I don't honestly think its vital though.
 
Are they doing the install? Did they say how long it will take? Apparently CPT does get more solar hours then we do up here on the highveld :-)

Nah doubt I need anything more than the basic power usage and where it’s going stats which that plug-in provides.

Running a cable and keeping it central is far easier than adding another Pi.

2-3 days planned for the install.

Ah cool, I take it they going to do the panels at the same time as someone is going to do the inverter? As the inverter seems to take a day by itself.

I'm going off memory as I wasn't really too fussed but I think it was...

Day 1 the Panels get started.
Day 2 Panels get finished and wiring run + Inverter and batteries get installed.
Day 3 Wiring completed and commissioned.

The vibe I got was that they pretty much expect to be done in two days and just do commissioning on the third day, but it's there for rollover in case of any issues.

Yeah sorry I was cross pollinating different conversations had before.

I’m aware of the options but for not going without Solar Assistant and will be using the direct Sunsynk integration into HA with the cable.

If it’s lacking for whatever reason I may spend the money and try Solar Assistant as well.

I'd budget another 1/2 day or so for a later visit to resolve small issues :)
 
What will this power and for how long? E.g. could a full charge last through the night, or for a cloudy day without power?
