I thought i was the only one…

I currently don’t have time to work on controlling, nor do i have a need to change my current NOM workmode.

From what i know now it should not be to difficult:
You can write commands to a specific topic witch the DR134 reads.
Before someting can change you have to change the command setting in ...

trying to install fresh on Ubuntu 24.04.3 LTS (for testing) (not Docker)

There are (3rd party) plugins for Blockly found here : https://www.npmjs.com/search?q=keyword%3Ablockly-plugin

Very useful would be : https://www.npmjs.com/package/@mit-app-inventor/blockly-block-lexical-variables
It seems to me that with this plugin a lot of new possibilities for scripting in ...

Do you have hourly values? In the other graph?

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 ...

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 ...

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 ...

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.

I dont know why the values can’t be seen in the forementioned device itself, there is also ...

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 ?

.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)
