Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
So far so good. 3 Automations at the moment.
1) Start charging
2) Stop charging when SOC greater than input
3) Stop charging and switch to auto
Also checking solar for tomorrow, just need to marry the two up after a few days of readings.
Auto.
Not sure what auto save does?
Battery save will charge but not discharge
So for those in my situation:
Sofar
Seplos
LifePo
Sofar2MQTT
Set up now in HA
Sofar manually set to "Passive Mode"
Charge to 3000W now currently working. However if I want to switch it off I turn off the button but I also have to toggle standby (if it's on I switch off and vice versa)
What I've to figure out now is come 8AM how do I get it to discharge and charge from PV etc.
I'm guessing I've to enable one of the modes but I'm not sure?
Auto Mode
Auto Saver Mode
or
Battery Saver Mode
Brilliant thanks!
I'm looking at the Shelly Pro 3EM:
It comes with 3 CT clamps, so is this all I need? So I install the 3EM in my consumer board/fuse box. Connect a CT clamp around the wire going into my smart meter and another CT clamp on the AC line coming out of the inverter? What is the home assistant? It it a device that communicates with 3EM and has an app I download?
Sorry for all the questions - I'm reasonably technical but a total noob with CT clamps and energy sensors 😥. I dont want to drill through walls so this sounds like a great solution if its all wireless.
Simply, A shelly EM3 + home assistant Or an EmonPi
A CT on your main grid, a CT on your solar feed and you can monitor/calculate all that
Hey I posted this in the wrong thread so I think here is the right place!
I got my install complete on Monday. It's a 6kwp south facing system (with Solis inverter), delighted so far!
I dont have a battery so didnt bother with the Hybrid solis inverter. On the Solis cloud app I am only able to monitor the power produced and the units generated by the system.
I would love to monitor 4 things:
1) Units generated by system
2) Units self-consumed by house
3) Units expored (FIT tariff)
4) Units imported
What is the most straightforward setup to do this? Wireless would amazing if possible, ideally with a simple software interface on the app side. I realize I could have achived this if I opted for the hybrid inverter but I didnt want to pay the extra ~€700. Options??
Hold on a sec. It absolutely does NOT need to be decent, and especially running Linux.
I got an old Thin Client tiny PC in work, whacked in an SSD and away we go. Anything even 10 years old will knock spots off a Pi really.
Also, I did run previously on a Pi ..... 2 !!! So you do NOT need a 4 or even a 3 TBH
aw sweet, Thats pretty neat
Yep bang on, charge at x until soc is the desired SOC. pretty simple.
Then you can expand on it, Stay in auto mode until a lower SOC is reached (eg for summer),
A VM dedicated to home assistant has no issues in terms of intergrations. It's basically the same as a Normal install.
It runs the Home assistant Os and supervisior.
There is VM for HyperV, VirtualBox, KVM, VMware..
There is restrictions with Home assistant Core i think though.
So I've enabled all these buttons at the moment:
So I guess I need to switch off time of use mode again.
Then at a certain time:
Set the charge @ 3000W until SOC greater or equal to my desired amount.
Seems pretty straight forward after?
Are you not constrained when running HA as a VM in terms of integrations?
I'd just go straight for an x86 device. I moved my setup from a RPi to a Dell Optiplex Micro running Debian/KVM a couple of months ago, and then run HA as a VM within that. Oodles of power and only uses 7W idling.
You can pick them (or the HP/Fujitsu equivalents) up fairly cheap on Adverts.
That's a great idea, get a feel for things and decide if you need bespoke hardware. HA doesn't require a lot of resources and the beauty of the Pi is that it uses minimal power. You could run HA off 10 watts versus 60/100 for a mini PC. A fast SSD or NVMe drive would give a big performance boost as well. I'll probably replace my 6 core polar lake Intel x86 media center with a Pi5 when those come out in 2024.
Thanks guys. I'll take a look this afternoon ,
I do have a decent PC that I really don't use anymore which I probably could use until I get a device like the ones mentioned above.
I'll you tube it and do a bit of research
Tks all ....
If you're new to this @The devils , note that this is just the I/O board and your would need to purchase a compute module to go along with this. You could pick up a model B which is an all in one solution.
I bought stuff here before and found them ok. https://ie.farnell.com/raspberry-pi/cm4io/compute-module-4-board-arm-cortex/dp/3563491
I put mine on a Nuc and it's well worth the extra 50 or so, speed is fantastic, streets ahead of the pi4.
Not sure what the stock situation is with the ordroids but they do HA well or so I hear
https://rpilocator.com/ is a good stock tracker. I bought mine through Berrybase.de, it was a pain in the head as I had to use a German Parcel Motel clone to get it over to Ireland at extra expense, but I got it. You could also purchase a HA Yellow. Lead time is very long but at least you're in a queue. https://www.home-assistant.io/blog/2021/09/13/home-assistant-yellow/
Alternatively, if you're anyway handy with computers you can get home assistant up and running on a normal x86 computer with Debian/Ubuntu though Ubuntu is not officially supported it's just a few extra commands to get it working. This is what I did so I could learn how to use HA while waiting for the PI.
Hi guys very hard to get a raspberry pi, seems like they are not in stock most places..would any of you know somewhere I might find one please
For the me3000, you'll have to set it to passive mode (it is a me3000 that you have right?)
So you'll need be telling it to switch between charge/auto/standby yourself. (Well your code will have to!)
I have it done in node Red but I've tweaked the code on the sofar2mqtt to report back what mode I'm in too but never looked at the rewrite (v2) , and work from that. And the code evolved over a year or so too, so it isn't the prettiest either!
Just wondering if this code is all still valid?
Also rather than changing voltages etc. etc. I'd live to just change the SOC I have set in the inverter (Solarman). Any advice?
Apologies for the replication here guys.
Setup with sofar2mqtt, ha, all talking to each other nicely. What do I need to do for the predictive SOC? Any doc? Link? I found a few posts here but there's edits after etc.
Also the energy dashboard is ok but it's displaying accumulated values instead of live (I think), I wasn't given an option to select the sensor / live options.
OK, I think I'll stick with what I have as I now have the remote configuration support in the App. It's not useful for automations but it's 80% there in terms of removing hassle. I might revise the decision at a later point in time as generally I dislike being dependent on cloud services (too many of them have disappeared in my past).
Not quite. I was talking to Francis about this and it is either or. i.e Solis Cloud updates stop while polling via Modbus TCP. Stop polling for 5 mins and data updates again to Solis Cloud.
Possibly workable with a 5 min stop/start at a quiet period of the day to keep Solis Cloud data synced.
I believe the S2-WL-ST is the sweet spot for Solis cloud and modbus compatibility though I don't have one. Solis themselves told me S2-WL-ST will work with Solid cloud and the HA Integration also lists it as supported.

Best bet is probably to post up in the for sale/wanted thread or on the Facebook group. Quite a few people have changed to the new logger who wanted the app access. That means the old Solarman logger sitting on a shelf somewhere. I did the reverse and sold my S3 logger to someone here. The place I bought the older one is out of stock now.
I looked into a few places that claimed to be selling the solarman models but after a bit of digging where actually selling the newer ones. It can just be sloppy product details.
Thanks! My first day looking for one so didn't want to get wrong thing. They seem good value but only delivery to Netherlands!
I can't find any mention of the +A -A aside from that site. It could be their own naming or perhaps the A is denoting inclusion of the aerial or not. I'm just guessing though.
