Alternative soft for DTS238-7 Tuya IVAP Energy Meter (without MODBUS) for COP and power measurement

Hello

I have a question if any of you may know if it is possible to integrate some software other than the org for such an energy meter, which I use for the heat pump.

My model DTS238-7 WiFi Tuya model IVAP unfortunately without MODBUS port
it works great counts nicely energy input and output, but what annoys me is this,
frequently and I can not calculate on the fly the COP and power of the main exchanger :/

maybe we could somehow work this out together ?

I am sending a link from github only there is only model with MODBUS...

https://github.com/arendst/Tasmota/discussions/16913

I would be grateful for info.

Hello, the linked description is about modification of a meter based on TYWE3S module, i.e. ESP8266. Is the version you have also built on TYWE3S?

In the linked topic there is also a suggestion to use MODBUS interface - your model does not support it?

I have to decompress in this case.
Type: IVAP does not support Modbus.
It is missing the output unless it is a small problem and it can be made?

And so it sits there WB3S pictures below.
Version with modbus has in circle I marked additional modbus output at me missing it

Unfortunately, I don't know enough about the device to know if the soft inside still supports modbus and the connector has simply been omitted, or if it doesn't support it at all. The WB3S (BK7231T) instead of TYWE3S (ESP8266) inside is also a surprise. Overall a very tough task you have set yourself.

One thing you could try is to hook up with the UART to the visible RX/TX from the WB3S. If this product uses TuyaMCU, it might be possible to capture something and then process it after a software change:

Unfortunately, it is a bit of work and capturing UART packets must be done with the device disconnected from the mains, so as not to short-circuit it. You have to power it safely somehow for this time.

A word of explanation - we already had on the forum devices with TuyaMCU where it was possible to change the batch and free them from the cloud, for example here:
https://www.elektroda.com/rtvforum/topic3941692.html
https://www.elektroda.com/rtvforum/topic3928897.html
By TuyaMCU I mean the structure of the device, that the measurements etc. are performed by the microcontroller, which then reports them to the WiFi module via UART (TuyaMCU protocol). Then you can relatively easily change the WiFi module software itself and process this data freely.

If, on the other hand, this is not a device with TuyaMCU, then playing around with protocol decoding would be rather too much to be able to make modifications in a reasonable time.

so I'm left in the black .....

this meter generally works mega cool, but it's slow to display instantaneous power consumption :/ unless it can be reconfigured ?

And what is in the Tuya app in the settings, what is visible there?

Even if it's the TuyaMCU, we don't know at this point whether the reporting frequency is limited by the MCU or the WiFi module, because if it's an MCU issue then changing the firmware on the WiFI module won't do us any good.

I don't know about that, but I'm afraid you may be right that it's not wb3s that does the measurements, but some microcontroller.
In the app there are quite a lot of settings


And in the reading of the current consumption I marked in the circle it refreshes very slowly.
.

And that 60 seconds isn't the option you're looking for? Just a guess....

I don't think it is
Or it is badly translated. ?

I will be trying to decipher this device together with @DeDaMrAz . Here's a pic fresh out of the box:

any popsteps? .

No problem to change the software, there are versions even still based on ESP8266 in the trade. Here the teardown:
