Hi, is there any display, like INK paper, that can be set up to show some sensor values. For example from PV, or temperature etc. Thank you

 

I like this - an example

Hello.
For creating your own control and monitoring panel design, you can use, for example

Please login or register to see this link.

It has instructions, libraries, a community forum,... You can then run it all on, for example, an old phone/tablet.
One of the promoters here on the forum is RH_Dreambox.

Otherwise,... for use with e-ink displays, you need your own development. I don't know about a commercial product
I had to do with ESP32 and a small 2.8" display the CPU usage indicator from HC3 (it was an era of not very well-debugged fw). At the same time, the display showed me the date and time. It all works when querying HC3 using the API, ESP32 performs the parsing of the result in JSON format and then renders it on the display. Everything works without any intermediate link like mqtt broker or any other microcomputer (RPi, NAS, etc.,...).
On the Internet there are a lot of instructions, libraries, how to work with e-ink diplers in the Arduino environment.
So... even if you have at least some experience, you can use some instructions to study, modify or write your own code. You design your own.

To the above.
Solar Station is a Czech product (and I like it).

The basis is ESP32S3 and Lilygo E-ink with accumulator.
The manufacturer put a lot of know-how and I have for not even paying it. Therefore ... buy, buy

For your own DIY (in czech "bastleni") can buy in CR here:

Or, for example, in Chine here:

And to the module, I will add significantly:
E-ink displays are not intended for applications with a frequent rewrite. So consider whether it is suitable for the applied application. Own overview lasts about 8-10sec.
f you want more frequent transcription, select some LCD/OLED display.

While I love the e-ink solutions mentioned above, I wouldn't limit myself to a small monochrome screen with indeed a low refresh rate.

 

I prefer a larger screen with real time display of the values. Influxdb2 could be a solution for that

 

And then a nice graphical representation with Grafana on a tablet. The possibilities are then endless.
