SA has no notifications as yet. Configurable notifications are on their list for inclusion in a future release.Does SA send notifications reliably?
With a single inverter and just a shunt for battery data, my SD card has used up 8% of a 32 GB card (~2.6 GB) over two years and a bit.so the logging limitation is mostly about not consuming storage.
Just set a static dhcp (reserve) on your router. I do that for SA, HA and other devices.I think the data on Solar Assistant is within 1-2 seconds of it actually happening, they only log at 10s interval into the DB. Some of the metrics, like kWh consumptions were only summed once every 24h before, they just changed that to be summed hourly. I implemented my own integral sensor in HA to do the summing and it works fine.
Why do you need data more often than what MQTT feeds into Home Assistant? There isn't a whole lot you can/should do faster than the ~3.5 seconds per MQTT packet that is received.
Also note that Home Assistant only saves every data point for 10 days by default, then it only saves min/max/average values in historical data.
Again, why do you need more granular data?
I've had this setup for a while and the worst part of Solar Assistant is the abysmal WiFi implementation on the Raspbery Pi and the lack of static IP address. I (hopefully) fixed both of those issues so I expect this thing to be super reliable going forward.
You set that in your router, not the RPi.I've had this setup for a while and the worst part of Solar Assistant is the abysmal WiFi implementation on the Raspbery Pi and the lack of static IP address.
Except that I prefer my static addresses to be of a different range than DHCP ones. Netgear's Orbi is pretty crappy with DHCP in general, so I much prefer true static addresses. I did manage to set it on the raspberry Pi eventually so I'm fine now, I'm crossing my fingers to see if the wired ethernet finally fixes my other dropouts.Just set a static dhcp (reserve) on your router.

Sweet. Notifications coming this month. Hopefully.....SA has no notifications as yet. Configurable notifications are on their list for inclusion in a future release.
I use HA to send our phones notifications for various things, including when the grid is offline, back online, amongst other more mundane things like when the washing machine or dryer have finished a load.
I've learned not to get hopes up as projected feature timelines tend to be pretty rubbery.Hopefully.....
Just curious which Pi you used?made the switch to Solar Assistant
I’m just starting this journey, any chance you are using Python and can share some basic subscription code? I can see parameters with:I wrote a program to subscribe to SA MQTT and display the data.
I do something similar with the EG4 18kPV by tracking the grid side voltage to detect brownouts and grid power loss in home assistant using a USB to RS485 interface. There is a copy of the Sol Ark modbus register map posted on this forum and it looks like there's a holding register 152 labeled "Grid side voltage L1-L2" and register 194 "Grid side relay status" that might be useful.I’m planning 2-Sol Ark 15ks and want to get that info into Home Assistant. The main item I need is grid on or off. When the grid goes down, I need that info to trigger in HA load shedding to the span panel I plan to install. Can someone confirm you get that info in HA with the Solar Assistant and HA integration?
Yes I know Span can automate this, but only if you purchase the batteries they support. I’m trying to get around this limitation.
It will depend on what data the Sol Ark supplies to Solar Assistant but I'd imagine that it would have AC input voltage and probably grid frequency. You can use those to set up an automation.Can someone confirm you get that info in HA with the Solar Assistant and HA integration?

Who are these guys you know and how much $$ do they require?I agree with everything you point out and more BUT he has produced a reasonably good product at a reasonable price and you can see improvements in the beta versions that are slowly coming out. The primary thing I find fault with is the documentation ( the help file) does a very poor job of indicating what is actually implemented for each type of inverter - thus you don’t really know what you are getting until you buy it.
It’s a good product considering it’s a part time effort for folks that appear to have day jobs earning a living working on something else. I know a number of guys that could quickly build a application that would run circles around Solar Assistant but they are not hungry and would expect to make a lot more $ than almost nobody buying Solar Assistant would be willing to pay.
Guy’s I’ve worked with reverse engineering turbine generator controls and communication interfaces. Hundreds of dollars per hour.Who are these guys you know and how much $$ do they require?
