I added using Tuya, but it only creates a switch… And indeed in Tuya app, the decimal is wrong, it’s 1 place shifted…
If anyone can share how to setup the other entities with correct dpi, would be 
Hi Fabio,
Which Weau pool heater do you have? I am not able to create anything… With Tuya local i see a device which i can not connect. Maybe you can also share your location and the steps you made.
Thanks
i bought this one, just paired with tuya “smart life” app, make sure you select the 2.4 Ghz , it doesnt support 5 GHZ

but i always have this error with tuya local, but i think because the address is already in use with localtuya discovery, tuya devices only allow 1 connection, so gonna restart the heater later, and try again
Hmm interesting. How did you get the Local key? Was it already filled in automatically or how did you get the key?
i grab it with the API explorer on the IOT cloud platform, its described on the integration page…
But i will stick with localtuya integration, gonna create the DP manually , was describing them for me now…
'1': false, => power on/off
'2': 'eheat', => mode
'9': 30, => temp set
'10': 203, => temp current , here is a decimal issue, should be "20,3"
'20': 4, fault => system fault
'101': 0, machine type
'102': 40, set temp upper
'103': 15, set temp lower
'104': true temp unit C or F
ok, Weau integrated, using localtuya, with config below
"data": {
"device_config": {
"friendly_name": "Weau",
"host": "192.168.0.76",
"local_key": "XXXXX",
"protocol_version": "3.4",
"enable_debug": false,
"entities": [
{
"friendly_name": "Weau",
"target_temperature_dp": 9,
"current_temperature_dp": 10,
"temperature_step": 1,
"precision": 0.1,
"hvac_mode_dp": 2,
"hvac_mode_set": "manual/auto",
"temperature_unit": "celsius",
"target_precision": 1,
"id": 1,
"platform": "climate"
}
],
utsing this card
Only thing missing is the “cool” button, but i dont use that anyway 
Fabio,
Nice work! Can you show me how you connect the Weau into Tuya? At my version it is now visable directlly. I have a different version of the Pool heater but i assume the wifi adapter is the same…
Thanks
Well, on the Weau , i had to press 2 buttons at the same time, than i saw a wifi led blinking (pairing mode)
Then in tuya app, within 30 secs you need to add the device , by just clicking “add device” in tuya app, if found the weau device very easy … , but only compatible on 2.4 Ghz wifi band
Fabio,
Thanks!!! It is working now.
Next step is to make some automations. Switch on / off heater etc.
Thanks al lot!
your welcom !
If you find the hvac mode to cool, cause thats missing, let me know 
Looks good. Is it a bit stable? My other tuya devices aren’t always seen online 
Mine is stable, I have a good wifi mesh inside and outside :+) , never have issues with my Tuya devices, I have 10 of them, led strips, pet feeder, star lights, gas detectors
Maybe I’ll try it again this weekend, the 2.4Ghz switch is always a bit irritating 
I can’t switch off my 5Ghz and can’t force my phone to use 2.4Ghz 
Your phone has no impact for connection issues between Tuya devices… Tuya devices need connection to 2.4, but your phone can still be connected to 5.0, there is no direct connection

Connected, but seen as v2. See if I can change it to 13kW
but to many options
Only when you click it. Default is set to silent heat
Can do more with automations now.
