3 phase energymeter and not blow the fuses

[intetiffanypersson]

I have a Solaredge 10k with the modbus energy meter. It's 3-phase, since I'm in Sweden (not sure if all of Europe standardised on 3-phase). The Smartmeter/EnergyMeter is also 3-phase.

From this I can via Prometheus and scripts I found online, get a lot of values. But not into Homey, yet. I'm thinking/hoping it should be "easy" to add a few cards with these values. Since I also have a "dumb" 3x16A car charger (Keba, another plugin) and my house has 3x20A import, I'd like to measure each phase once a minute, from the Solaredge modbus data, and shut down or reduce my charging if any of the phases are exceeding 20Amp import from the grid. Otherwise, if someone starts cooking while the car is charging, the main fuse will blow. Or if someone showers, or starts a washing machine etc, etc. So many opportinitues for my family to yell at me...

So basically what I need is for the Solaredge plugin to present more cards with values from the modbus registers. Specifically for me, from https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf I THINK I want from Meter1: 40191 40192 1 M_AC_Current_A int16 Amps Phase A AC Current 40192 40193 1 M_AC_Current_B int16 Amps Phase B AC Current 40193 40194 1 M_AC_Current_C int16 Amps Phase C AC Current Not a 100% sure how that works, but the Smartmeter is connected to the incoming Grid, not really the Solaredge, so I'm thinking this should be it... With that I could make a flow that is like "If Phase A or B or C is greater that 20Amp, then set carcharger to 10A".

Thanks for a wonderful plugin, the modbus connection possibility is is just awesome!

nice,

so I am looping over the 3 meters https://github.com/biemond/solaredge.modbus/blob/main/drivers/solaredge.ts#L93 but indeed only do meter 1 , extra meter is no issue https://github.com/biemond/solaredge.modbus/blob/main/drivers/solaredge.ts#L316

everything is flexible for me and easy to extend. currently meters are under battery , even if you have no batt you can still use it , I detect what is there.

but for the extra 2 phases can send me a diagnostic report from my homey app and I will get all possible values , so we can look together at the values register and see what you need.

thanks Edwin,

hey,

when you on hemoy , add device with battery on my app . if everything is working you can go to more, apps , select my app , settings and do create diagnostics report.

I will get that and see your data.

[intetiffanypersson]

Excellent, I added it as with battery and created the report.

besides the totals which you are already can see .

so you like to see these current ones or not. Also something from meter1 ?

for If Phase A or B or C is greater that 20Amp I see I don't do current, I do power and voltage but no current.

Hi, I'm not 100% sure and it's hard to tell while looking at numbers that aren't realtime, but I think the ones in the last port are what I want. We can call those "Grid_import_L1", L2, L3 or something. meter1-l1_current 115 xxx L1 Current meter1-l2_current -8 xxx L2 Current meter1-l3_current 30 xxx L3 Current I'm guessing that is my grid import/export, positive is importing, negative is overflow from the panels as export. So 1,15A, -0,08A, 3.0A. Certainly, while you are in there, seeing the each pjhase solar production would be nice too, it would allow me to automate other things based on the panels.

l1_current 75 xxx L1 Current l2_current 90 xxx L2 Current l3_current 76 xxx L3 Current

Let's start with that and I will confirm once I can see them in Homey, in realtime, and compare with mySolarEdge app.

[biemond]

cool, so tonight you will have a version to test this out.

[biemond]

[biemond]

here we go https://homey.app/nl-nl/app/solaredge.modbus/SolarEdge/test/

let me know if it works.

[intetiffanypersson]

Yeeeeeeey! It works!!

Thanks so much! Awesome!!
