Rather than making exportlimitenabled/exportlimitpowerrate globally setable (which risks issues on TLS and other variants without a compatible Modbus meter), I added an ‘ems\_control’ checkbox to the regular Growatt driver settings. Only when the user explicitly enables this will the capabilities become writable and the registerCapabilityListener ---

Ah, yeah, that’s the same I did for the Growatt TLS, must have overlooked that. ---

@Edwin_Biemond I have tested to read register 3036 with the modbus app and this works fine, could you please implement this in this app? ---

Hi Edwin. Thanks so much for this app! Got it working with my Sungrow inverter to see solar generation. It would be great if I could also see my meter consumption too. My setup: Sungrow SG10RT + WiNet-S2 + SG Smart Meter (DTSU66). iSolarCloud shows consumption correctly. Modbus TCP 502 works. Sungrow String driver only shows PV power. Need SG Smart Meter registers exposed. Is a Sungrow + Meter Homey device in the pipeline? Hope it’s an easy addition. Thanks ---

Dears, i am using the app to integrate my kostla plenticore. It works perfectly. Now i want to get the values, especially the battery into the Homey Energy Diagramm. Is there a way to do so? Many thanks in advance ---

Hi again Edwin. A quick question. Is it possible to have a more frequent update interval rather than the 30 second interval? I use the Modbus option, which has been working perfectly 🙂 ---

not really , I have all the data but homey want to force to have 3 different devices when I have 3 in 1 . pv, meters and battery. they need to come with a new class and specify the energy caps. few already asked homey for this. in the mean time check how far you come with some virtual device ---

it depends what device you use , some are super slow like huawei , some are are fast like solaredge. but why do you want faster , like always use average values like 5 min values. else you respond to fast etc. ---

I have a growatt sph3600 inverter but with the modbus set up The reason I want faster updates is just because I eagerly follow production and if it’s possible then it would be great 🙂 ---

Thanks, I did try that yes. Only solar power value correctly shows. all other fields including anything relating to the meter don’t have any values. ---

Don’t really understand what you mean here, but the write function is already implemented. Maybe you could check how it’s handled there? ---

I am actually already using that flow action to change the percentage, and it works great. However, what I am looking for is a way to **Read** the current register value into Homey. I would like Homey to know what the current grid first discharge percentage is actually set to (as a sensor / capability), rather than just sending a command to change it. Is it possible to add a read function/capability for this specific register?"
