[APP][Pro] Marstek Energy Storage

The Marstek Energy storage app: V1.1.0.

My Homey Pro 2023 just updated to V12.8.0.

Mobile app (Android): V9.6.2

Android version: 14

My Marstek Energy storage app is now using 64.1MB at the moment. Connection to the batteries (via LilyGO) is getting better, but stil loses connection every now and then. What has changed is that it automatically reconnects after a few seconds. Very strange, will monitor some more and keep you posted.

@Kaoh, do you have any idea what could be happening? Would a diagnostic report help?

Pffff. Energy tab worked fine for some hours. (After firmware update 12.8.0) but now same problems. :scream::sob:

Crashes with 2 batteries

Hi,

Can someone help?

I have the Venus v3 with the ew11 but i don’t have no values is homey. My ew11 was configured in modbus so?

I have a marstek v2 and that is working fine

@Stijn_Van_Heeswijk hoe heb jij jouw v3 aangesloten met de EW11? Bij lukt het niet.

Ik heb eens een andere utp snel open gedaan en zo losgekoppeld. Hij krijgt wel voeding maar geen data.

Als ik diezelfde ew11 gewoon aan mijn v2 steek krijg ik wel data dus het ligt puur aan mijn aansluiting

Check the tweakers post in the start post, the V3 has a different wiring scheme.

The mains output current in the app is still incorrect. P=UxI makes PĂ·U=I and that’s WĂ·V=A wattageĂ·volt=current. Is this something that can be adjusted, or does this come from Marstek?

In the picture it’s 224,8Ă·100=2,25. That is wrong!

It’s read from the modbus

Ok, thanks. It is what it is then..

for people who have 2 or more Marsteks:

The energy tab crashed when adding more than 1 battery. This was not only with Marsteks batteries but also with batteries from other manufacturers. Today a new update for the homey app for iOS was published (9.6.3)

This update fixes the problems :star_struck:

Please keep the thread in English :wink:

I personally dont have two at this moment. But there are multiple people using multiple batteries.

Each requires their own EW11 device properly configured and each needs to be added individually to Homey. Then you can control them all individually. I did not test operation in group modes for example.

The messages above talk about the energy dash in homey having troubles but that should be fixed now, was a generic Homey app bug.

Hi. I do indeed have two batteries that I can control independently with my Homey. They can be controlled manually or with flows.

Right now, I’ve only tried some simple flows. But when I have more time this winter, I’ll definitely continue working on this.

I can imagine that the first time you read the above, you’ll find it overwhelming. But in my opinion, it’s definitely worth it. I finally had it up and running properly within an hour.
What do you have?
Do you already have ew11?

Good morning. I don’t have an EW11 yet. I need for each battery 1x Ew11? I’m really a newbie when it comes to Honey and EW11. Step plan is in this topic?

Yes. That’s wat I did

2 EW11, and steps as in this topic. Also the tweaker link for cable and ew11 configuration (step 1 - 8)

Succes and let us know :+1:

Hello Francois, I keep having connection issues. But I must admit that I didn’t have time the last couple of weeks to tinker with it. When I do get it working I will post here again.

Hello Daan, no problem, let me know when you found something.

Oke Guys, Im confused. My Marstek Venus V3 is on its way.

Question 1. What do i need to setup to use this APP?

A modbus to wifi gateway, the EW11 is the one that was used to is and test the app with.

See starting post for info and links to instructions how to wire it.

There is now also a local api app available for Homey if you’re battery has support for it and it covers your needs.

What do you mean with also a local API app?
