I tested this version and I see the info and the card. I have tried a new flow to reduce to 1% or 99%. I can see the value being set, but after 1 minute or so it reverts back to 100% without me doing anything or a flow. No change in power though I am so frustrated!! Is there someone else here that has a (sort of) same inverter Solaredge HD 3680 with lcd screen, and is willing to send me screenshots from all the settings you have with a working setup and this app? I want to make sure I don’t have a new setting somewhere and that is not right. Just to make sure I am not crazy or Solaredge is remote f.cking around ---

Hi Edwin, I put a 2nd (LG) battery into service today. everything is perfectly configured and visible in the SE, but it does not appear in the homey app, am I doing something wrong or this option is not available. ---

hey, problem is they are the only 1 where it requires some login on some registers which is not described anywhere. there is 1 HA impl who can do this but I need to understand it and reverse engineer it. I enabled it again on this version [SolarEdge + Growatt TCP modbus | Homey](https://homey.app/a/solaredge.modbus/test/) as device actions. you can try it out if it works for you. ---

was thinking I did it by default , let me enable the 2nd one for you. ```auto battery_dids: Object = { "batt1": [0xe140, 1, 'UINT16', 0x0], // "batt2": [0xe240, 1, 'UINT16', 0x100] } ``` Can you try this 1 [SolarEdge + Growatt TCP modbus | Homey](https://homey.app/a/solaredge.modbus/test/) and send me a report 5 minutes later. ---

let me add 2nd ones , maybe add average batt and also show the 2 batteries. ```auto batt1-c_manufacturer LG xxx Manufacturer batt1-c_version DCDC 1.2.18 BMS 2.3.0.4 xxx Version batt1-c_deviceaddress 15 xxx Modbus ID batt1-rated_energy 9623 xxx Rated Energy batt1-soh 97.69999694824219 xxx State of Health [SOH) batt1-soe 93.5 xxx State of Energy [SOE) batt1-status 3 xxx Status batt2-c_manufacturer LG xxx Manufacturer batt2-c_version DCDC 1.2.18 BMS 2.3.0.4 xxx Version batt2-c_deviceaddress 14 xxx Modbus ID batt2-rated_energy 9623 xxx Rated Energy batt2-soh 100 xxx State of Health [SOH) batt2-soe 5.400000095367432 xxx State of Energy [SOE) batt2-status 10 xxx Status ``` ---

In the SE app they also use an average for the SOE, can each battery be read separately for calculation? ---

Hi, I have managed to get it working in the meantime. Thanks a lot for your work. Is there any way I can influence how often the data is retrieved from my Huawei inverter? At the moment, it is about every 2 minutes. Every minute would be nicer. Regards, Björn ---

s-dongle is very slow on startup, have to retry more with some time in between to make it stable. especially with battery and meters. most optimistic it takes at least 55 seconds Are you using s-dongle? ---

So, I seem to be the lucky one! My Huawei Inverter (plus sDongle) give me updates every 30 s! No battery though.
