Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Depends on inverter and if you're sending the data to HA?
The inverter is already sending data to HA. I'd like to have a daily SOC low before sunrise, PV peak, time when battery reached 90% and 99% in the morning.
Solcast et al are not that great so I am just going to take seasonal averages for the battery to charge up in the morning and want to have the data there, waiting for me in the morning, rather than having to trawl through charts and work the figures out.
I'm using the Solarman integration
https://github.com/StephanJoubert/home_assistant_solarman
How do I go about creating an automation in HA that records the daily peak PV input
Is your inverter sending a daily yield value in kWh? If not, what about a total yield in kWh?
Use a utility meter with the sensor pointing at one of the kWh counters and specify the reset cycle like this:
utility_meter: solar_hourly_energy: source: sensor.solar_energy_total_sum name: Solar Panel Hourly Energy cycle: hourly solar_daily_energy: source: sensor.solar_energy_total_sum name: Solar Panel Daily Energy cycle: daily solar_weekly_energy: source: sensor.solar_energy_total_sum name: Solar Panel Daily Energy cycle: weekly solar_monthly_energy: source: sensor.solar_energy_total_sum name: Solar Panel Monthly Energy cycle: monthly
Another option is to use a Riemann sum with "method: left" and let that do the counting cycle.
daily minimum State of Charge etc.
I think that a "min" integration would do this:
You can use a helper to set it up instead of using YAML but you may need an automation to trigger the action just after midnight (I think).
Unfortunately to do it using in-built components is a bit of a faff as @10-10-20 has highlighted.
Easiest solution is to use this custom component from HACS.

@10-10-20 & @Jonathan Thanks. I've been fiddling with Helpers today and have a Min for SOC. I'll put together some logic for time when 90% and 99% SOC is reached. So long as I can see these, at a glance, in the morning rather than having to call up a chart and read them off an axis then I'll be happy to input them myself into a spreadsheet.
What's happened to Home Assistant? I got a core upgrade today so as usual I updated.
Now, I can't restart my LocalTuya Integration nor a few others that I've tried.
Sometimes, LocalTuya loses contact with one of my smart sockets so I go into the LocalTuya integration where there is an option to Restart it. Now, after the core upgrade, this option is no longer there. How can I restart a single integration? Do I have to restart the whole of HA from now on?
Hi folks,
I have home assistant running on raspberry pi 3b, using 500gb SSD drive. It's all running perfectly and I take daily backups to Google drive. If I've a power cut though I seem to loose the pi and the only way I can get it back is boot from micro SD, flash the SSD drive again, reboot and restore a backup.. thankfully that gets me back up and running but it's a bit of a pain. Apart from a ups, what else could I be looking at?
Cheers,
Mick
Well as the pi b runs on a USB, a USB power bank? Use the power bank as a ups.
It shouldn't be dying due to a power cut though.
Yeah that's what I'm thinking... Are there any ups power banks that you can run off plug and will keep power when it fails? Something like this I guess?
https://www.amazon.co.uk/Yangers-uninterrupted-supply-8800mAh-battery/dp/B09GNV4FV3/ref=mp_s_a_1_3?crid=36L5CMS5OUTMC&keywords=usb+ups&qid=1686429168&sprefix=usb+ups%2Caps%2C129&sr=8-3
Sounds like a filesystem problem due to an unclean shutdown Mick. Ideally you need the Pi to do a clean shutdown once it's running off that USB UPS. There are Pi UPS's specifically for that. You could script that by pinging a device such as the router which fails when the power is gone and the the script shuts the Pi down. Maybe somebody already published that type of a script already.
I see some examples of pi ups boards, Any with cases? Or would I have to recase mine pi 3?
Probably. They tend to plug into the Pi headers and double the height of the Pi.
That's mine in dashcam config (missing the LiOn battery and top of case) for mounting in a footwell during a road-trip. That metal case just happened to fit the Pi and UPS.
Strange one, I use a similar setup with a pi4 and it never happened when I lost power, in fact I have the pi on a smart switch that I can toggle on and off if it ever hangs on me.
If you have batteries with your solar you could use them as a gigantic UPS with something like this: https://solar-assistant.io/shop/products/dc_usb_psu_type_c or wire the pi to the backup port on your inverter which is still powered by your batteries, that's what I do for the pi and all network gear in the attic
It's actually on the ups circuit from my inverter but I had a weird issue last night where the inverter tripped it's RCD and the power from the EPS socket took a fraction to kick in.. during an actual power cut recently it was fine
I see, so maybe something like this https://www.aliexpress.com/item/1005005071564178.html?spm=a2g0o.productlist.main.1.6a4f67afbu4S6H&algo_pvid=97000079-368e-4447-95d8-81d873fbc5f0&algo_exp_id=97000079-368e-4447-95d8-81d873fbc5f0-0&pdp_npi=3%40dis%21EUR%2142.27%2138.04%21%21%21%21%21%402100b1a616864995121743328d0783%2112000031524797081%21sea%21IE%21795413750&curPageLogUid=NCo4MU8MwxNX would have kept it alive?
I ordered a pijuice hat.. so I'll see how that goes
Yeah let us know how it goes, I might throw one onto mine as long as it takes lifepo4 and not just lithium batteries.
I forgot I have one of these hats on my pi https://www.aliexpress.com/item/4001272206755.html?spm=a2g0o.store_pc_groupList.8148356.4.66eb4b4aTFRkXQ&pdp_npi=3%40dis%21EUR%21%E2%82%AC%2050%2C39%21%E2%82%AC%2044%2C84%21%E2%82%AC%2044%2C84%21%21%21%21%40211b88ec16865193651111878e8c03%2112000016797922858%21sh%21IE%21795413750 I just need a battery + housing 😁
Anyone familiar with Grafana for homeassistant? I want to create a panel that tallies up the daily total in euro from the kw/h imported.
Using this query to gather the kwh
SELECT mean("value") FROM "autogen"."kWh" WHERE ("entity_id"::tag = 'myenergi_my_home_grid_import_today') AND $timeFilter GROUP BY time($__interval) fill(null)
and if I do a math function of say, $A * 0.39 I'll get both the kwh and result in the same panel.
It's been years since I've worked with Grafana, it's changed so much!
Basically I want a box that performs the calculation with the Euro symbol. Any ideas?
Never mind, figured it out!
I have the home assistant built in energy dashboard doing this calc for me:
Do share the solution, I haven't played with the database queries but I didn't like how HA works with Grafana when I last looked as I hard to search by the unit of measurement. Maybe that was just how I set it up.
I moved away from RPi and use an old old laptop. Cheaper and less hassle. Cards have always corrupted on me over the years no matter what precautions I've taken.
Running off SSD and don't forget your daily backups.
I'm running an old Thin Client PC imaged with Linux Mint
Looking for any pointers here if anyone else has had similar problems. Trying to run the neey monitoring on home assistant.
Got esphome setup on two separate esp32.
added device in ha, edited it using the code on the following page https://github.com/syssi/esphome-jk-bms
then changed my Mac address for neey, and the API key. Added my WiFi credentials to the secret yaml. Shows the device as online and add it to esp integration.
However no joy and not reading anything. Logging into the neey with phone and Bluetooth works instantaneously any time I try that so not sure why the esp is not picking it up.
Finally after weeks got this going tonight and connecting fine to neey now.
For anyone else with this issue it seems pyparsing version crashes it since recent esphome update. Doing clean build files, then install and it recompiles to a working state.
Hi, maybe someone can help me, have recently had a solis hybrid inverter installed but I noticed that the serial number on the data logger is alpha numeric. I've no idea what version it is. I tried the pvsolarmanv5 code but I get a "no socket available" error. I presume I don't have the correct data logger? Can some one recommend which one I should get and where? TIA
Just get
A) a Shelly EM
Or
B) another MyEnergi CT clamp
looking at another inverter rather than Seplos.
can any match the Seplos in terms of automation features? Ideally a 6kw hybrid.
thinking sunsynk
