And what @jvdz mentioned? Maybe port 1883 conflict? How long is keep-alive on mqttmapper and your tasmota? Ai answer : Port 1883, the default port for unencrypted MQTT communication, remains occupied for as long as the MQTT client and server maintain an active connection. The duration of this ...

Did you already set the sending time from the DR134 to a slower rate ?
I have 1 second, but with a slower Mqtt broker choose a longer time?

Thank you i downloaded the files. I see its in C++ and i should be able to understand most of it.

Power line. Why didn’t I think of that. Ordering a puser at alie now. Thank you for all the responses. In other news: I made a plugin for the ct003 to get the data over to Domoticz without the need for a puser. You can find it here: https://github.com/Haaibaai/Domoticz-Marstek Nice! About using the ...

I am drilling holes everywhere in my , before ethernet, house to get cat5e everywhere. But for the Marstek in the garage it was quite easy as my meterkast is directly connected to the garage. Just 2 holes, one for ethernet and one for connecting to a free 16amp group, where needed. i am looking into ...

Oke, thank you.

My original idea was to simply show what is going on behind the door of the electricity closet, so electricity in / out etc. Just simple text that fits on a 2,9 inch.

The e-paper is new to me so i have to see what happens.

But ideed flickering could be an isue.

I have the dr164 too and it hasn’t edgecomputing. Only the latest dr134 has it. I asked Puser and they confirmed that. I told them there could be a hugh demand for an edgecomputing wifi device. Maybe in the future. You can use a ethernet powerline adapter. TP-link has several sets. I tested one set a ...

Yes that did it : Changed MPWR to : "mapping": {"item": "params/r_data/2/value ;~0 ", "multiplier": -1, "digits": 1} Now the actual power value is displayed in the device mentioned before : T: 0.000 kWh, A: -467 Watt. Since the power is positive and negative Total will be the balance (loss went to ...

Nice project. In september 24 i bought a small 2,9 inch e paper module to build a display of energy usage/flows for my energy closet door. I did not find the time to get this running Domoticz, so a starting point would be very nice. In time i will pick it up and see if i can fit the energy flows etc ...

The actual power in watt is avaiable , in my opinion wh does not work here. These are different values and are read in the P1 device. For me the current results are fine they show me exactly what i want , per second. We should not forget this is basicly a work around. But i like it that much, and ...

@eddib : ive gone through al that, but the final result was not usable for the task.
i can accept that something doen't work in one way , but works great for my needs.


@waltervl , there is only one value. any other counter that is useable? (also in the power dashboard)

I have that too. But the power is displayed correctly in energy dashboard (and calculated with) and on my dashboard (when starred) and on the setup>devices tab. https://i.postimg.cc/GpvC7XtG/IMG-1806.jpg I dont know why the values can’t be seen in the forementioned device itself, there is also no l ...

you have to leave out the slashes !

happy to hear you got it working to!

you can easily add your own readings from registers.

Have a modbus device like the Homebattery Marstek Venus V2 5,12 Kwh and want a direct connection not using the API ? No more waiting until data synchronize or wondering where the data went. Like this ? https://i.postimg.cc/CxkKfRCr/showoff.png With just a few minutes of your time, a few easy steps ...

.counter didn't work. But i had unforeseen success with getting value's directly into the P1 device from Mqttmapper !! (tried a lot of things before but didn't work out) Current working: "Battery": { "topic": "Marstek", "key":"Battery", "type": "250", "subtype": "1", "switchtype": "0", "mapping ...

I have these values now : https://i.postimg.cc/RCRfHzTd/devices-now.png https://i.postimg.cc/4NxcvFLg/devices-util.png MTCE “total charging energy“ MTDE “total discharging energy“ MDCE “daily charging energy“ MDDE “daily discharging energy“ MMCE “monthly charging energy“ MMDE “monthly discharging en ...

i set the sending time to Mqtt to 10 seconds. data is now stored at Marstek, and visible in the app. After modbusconnection the app still works, but a bit more sluggish. From the register information it seems the battery can also be controlled over the modbus connection. But my only goal is to ...

I had the same issue with the Battery, it had a too weak wifi signal. Putting an old accesspoint close to it made it work much better ... I also swapped the CT003 for a HomeWizzard P1 ... Looks it is stable for a couple of days now. The original app is sluggish ... My modbus-wifi adapter arrived ...

Oke, in time, when everything works the right way. The Github is already there : https://github.com/RneeJ/Domoticz-Marstek Next step beyond reading values is to control the device easily from within Domoticz. I even are going to try to use the DR134 on my Goodwe convertor. Both should be (quit ...

Well, had some troubles (works like hell, ahum) with the Marstek Venus (battery) to keep it connected to the CT3 (P1 reader). Now it has its own (very old) wifi router very very near by. Wifi - Signal strength is 96 tot 100 %. Seems to work, i hope. My previous mentioned Github published solution ...
