Tuya (or local tuya) smart water heater pump - not updating

1

Hello everyone,
I recently got a new water heat pump, and the external wifi kit uses smartlife app.
Tuya does not recognize any DP_IID’s but locaTuya does, and I’m able to get the ones that I want (current temperature, status, etc). However just noticed that the DPs are not updating, so I don’t get any temperature live updates.
The only way to get them is to go to the smartlife and, for instance, change the working mode from Auto to Eco, or equivalent. In that moment the other DPs ge updated in the Tuya Cloud and also in HA.
So it seems that the wifi module is not actively geting the updated device status.

Dows anyone had a similar case?

Hello guys, anyone?

I have an Energie brand, ECOTop heat pump water heater that I just had the WiFi adapter changed to one that is Tuya Smart Life based. The previous WiFi adapter was some proprietary system that only worked with the vendor’s app. I have tried to get this unit to work in HA using the Tuya Integration. The device shows up as “Smart Heat Pump”, but it doesn’t have any entities. I haven’t tried any other integrations like Local Tuya. Is this similar to what you are seeing?

Hi,
I did the same. I had the old one and with the new module it uses Tuya platform. Unfortunately is not a tuya fully supported so in order to get data you will need to use Local Tuya instead.

Were you able to make it work?

I was able to add my heat pump in localtuya and I get a set of DPS. The set is smaller than what I discovered via Tuya Developer Cloud. However it seems the data is only updated once at boot, it doesn’t get refreshed. I’ve been playing around with Tinytuya to debug but cannot get it to work.

I was not able to get Local Tuya to run, so I went with the Tuya integration which recognized my heat pump water heater smoothly.
I confirm, there are only few data points available, but they update just fine. An ugly thing is: the Set Temperature is wrong by a factor of ten, meaning it shows 5.0 instead of 50°.
I have not yet ckecked the Tuya developer Cloud for correctness of the source data. I consider it useless, because the Tuya SmartLife app displays the correct values.
Are there any hints? Can anyone locate the error? Maybe in the Tuya integration? Has anyone seen the same symptom?
Thank you.
