Can you give us the code of your configuration ?
Hi,
It’s just the “Thermostat” Card.
Try to integrate it in Tuya App and then integrate Tuya in HA, local or cloud.
Most of the heat pumps are basically the same rebranded model. So, the possibility of going with Tuya is very high.
I’m getting also somewhere, but now i don’t know it anymore.
did get a Tuya device seen in HA. but it’s unsupported, so don’t see any entities.
But at the diagnostics I see no special things. see attachment. tuya diagnostic
Anyone a idea how to get the entities of the Tuya device i got.
Dear Frank,
I have the same Weau heater only a bigger one. The 10kW. At the moment I only have the option auto heat and off. For some reason Heat is not working anymore. Can you tell me how you integrate edit the YAML file. For me it is not clear how to get all the options.
Thanks.
it depends what integration you want to use? i use localtuya, you can use these options below, you need to manually add it when adding the device in localtuya
Hi,
I’m using the Tuya Local, as it has some more options.
I’m using the normal Thermostat Card:
type: thermostat
entity: climate.w_eau_pool_heatpump
Fabio, many thanks for all the information shared. I have been able to add the (2) Weau heat pumps with the local keys, etc, etc.
The only thing I can’t get solved (I have done many, may, searches) is how to change the platform “climate” to use the simple-thermostat card instead of the default one. Understand that somewhere there must be a YAML file where I need to edit this reference. I have been looking around in the .storage folder, however so far not been able to find the line to edit. Can you help ?
i use this yaml:
- type: custom:simple-thermostat
entity: climate.weau
layout:
step: row
header: false
control:
hvac:
_name: Operation
Thanks Fabio for helping,
I have added the following lines to “/configuration.yaml” :
However when doing a configuration check, i get the following error:
Invalid config for ‘climate’ at configuration.yaml, line 20: required key ‘platform’ not provided
I then tried several attempts to add a ‘platform’ key, however it is clear I lack the knowledge to get this right. Can you tell what am I doing wrong and perhaps maybe in the wrong configuration file ?
Question: do I have to remove the Weau Heat Pump from the Tuya Smart app for it to work or can they co-exist ?
BTW: below the entry in the core.config_entries file:
Are you sure your climate entitie is created?
This what I see, however it has a warning icon, status “not available”
I think I am starting to see where I went wrong. Needed to add the Card to the Home page and edit. Added your code, however now I run into the below error. I have checked and also re-installed through HACS and also see the resource being available.
the simple-thermostat is also visible in the folder and added to the configuration.yaml. Staring to get lost …
Yeah, a common cause of custom cards not found, is cache 
Finally after a full day, found the root-cause. When adding the device (heat-pump), I had to select the 3.3 protocol and not the (newer) 3.4. Now the entity is available and can be added to a card. The only problem I still have is that the DP list seems to be different for this version of the Weau 7kw heat pump (purchased in 2023). Example “target_temperature_dp”: 2 instead of 9 as with your config.
You mention above that you where able to extract the DP codes from the API explorer. Can you give me some guidance on how and where exactly did you find the right DP entries ?
will also start to read this : LocalTuya - Using Tuya IoT Platform to obtain not only Local Keys, but also DP (data point) IDs
Sure, I added the guide here… But if you scroll down, there is an easier method with the API explorer, if you change the method…
Thanks and managed to get nvm/npm installed etc.
After running the ‘node cloud.js’ i did get the available DPS codes as follows:
group: "Mijn huis .." device: "Weau_WP1" devDPS: "{ '1': false, '2': 35, '3': 162, '4': 'eco', '6': 0 }"
group: "Mijn huis .." device: "Weau_WP2" devDPS: "{ '1': false, '2': 35, '3': 158, '4': 'eco', '6': 0 }"
Thats a good start
Also below the ‘raw’ data obtained from the device using the Tuya, Cloud > API Explorer > Device Control > Query Things Data Model:
{
"result": {
"model": "{\"modelId\":\"000003p0fy\",\"services\":[{\"actions\":[],\"code\":\"\",\"description\":\"\",\"events\":[],\"name\":\"默认服务\",\"properties\":[{\"abilityId\":1,\"accessMode\":\"rw\",\"code\":\"switch\",\"description\":\"\",\"extensions\":{\"iconName\":\"icon-dp_power3\",\"attribute\":\"1024\"},\"name\":\"开关\",\"typeSpec\":{\"type\":\"bool\"}},{\"abilityId\":2,\"accessMode\":\"rw\",\"code\":\"temp_set\",\"description\":\"制热8-40\\n制冷8-28\\n自动8-40\",\"extensions\":{\"iconName\":\"icon-set\",\"attribute\":\"1024\"},\"name\":\"温度设置\",\"typeSpec\":{\"type\":\"value\",\"max\":60,\"min\":7,\"scale\":0,\"step\":1,\"unit\":\"℃\"}},{\"abilityId\":3,\"accessMode\":\"ro\",\"code\":\"temp_current\",\"description\":\"\",\"extensions\":{\"iconName\":\"icon-dp_temp\",\"attribute\":\"1024\"},\"name\":\"当前温度\",\"typeSpec\":{\"type\":\"value\",\"max\":1500,\"min\":-300,\"scale\":1,\"step\":1,\"unit\":\"℃\"}},{\"abilityId\":4,\"accessMode\":\"rw\",\"code\":\"mode\",\"description\":\"hot：强劲制热\\ncold：制冷\\nauto：自动\\neco：节能制热\",\"extensions\":{\"iconName\":\"icon-dp_mode\",\"attribute\":\"1024\"},\"name\":\"工作模式\",\"typeSpec\":{\"type\":\"enum\",\"range\":[\"hot\",\"cold\",\"auto\",\"eco\"]}},{\"abilityId\":6,\"accessMode\":\"ro\",\"code\":\"fault\",\"description\":\"1:传感器故障\\n2:排气温度过高\\n3:高压故障\\n4:低压故障\\n5:水流故障\\n6:出水温度过高\\n7:出水温度过低\\n8:进出水温差过大\\n9:直流风机故障\\n10:盘管温度过高\\n11:驱动通信故障\\n12:预留\\n13:压机驱动故障\\n14:压机过流\\n15:输出缺相\\n16:采样故障\\n17:紧急停机\\n18:DC电压过高\\n19:DC电压过低\\n20:AC欠压\\n21:AC过流\\n22:E2故障\\n23:AC过压\",\"extensions\":{\"iconName\":\"icon-baojing\",\"scope\":\"fault\",\"attribute\":\"1024\"},\"name\":\"故障告警\",\"typeSpec\":{\"type\":\"bitmap\",\"label\":[\"1\",\"2\",\"3\",\"4\",\"5\",\"6\",\"7\",\"8\",\"9\",\"10\",\"11\",\"12\",\"13\",\"14\",\"15\",\"16\",\"17\",\"18\",\"19\",\"20\",\"21\",\"22\",\"23\"],\"maxlen\":23}}]}]}"
},
This shows that the control values for the DP:4 entry (mode) is r/w with the following values: "hot","cold","auto","eco"
How/where to configure these values ? I have tried tinkering the “hvac_mode_set”: “manual/auto”, line in the core.config_entries file for this entity, however with no success so far. Anybody that can help me with some pointers to where to mod these values ?
This what I have in the core.config_entries file for this device:
"entities": [
{
"id": 1,
"friendly_name": "Weau-WP1",
"target_temperature_dp": 2,
"current_temperature_dp": 3,
"temperature_step": 1,
"precision": 0.1,
"hvac_mode_dp": 4,
"hvac_mode_set": "manual/auto",
"temperature_unit": "celsius",
"target_precision": 1,
"platform": "climate"
}
See below what I have till now (at two Weau Pool Heat Pumps are visible and working, however not perfect yet as I only have ‘heat’ and ‘auto’, where we need ‘hot’ / ‘cold’ / ‘auto’ / ‘eco’ ):
I have been tinkering with the Card configuration, however no matter what I try, I still have 3 buttons, where I can change the labels/icons etc, however it will not send the required commands to the entity/device.
see below example code:
type: custom:simple-thermostat
entity: climate.weau_wp2
layout:
step: column
mode:
headings: false
header: true
control:
hvac:
'off':
name: 'off'
heat:
name: Eco heat
auto:
name: null
and the resulting Card:
In the above screen shot, the State shows ‘auto’, however the heat pump is actually running in ‘eco-mode’. Also the right button has turned green, based on the (wrong) State.
Any help and guidance is much appreciated and a BIG thanks to Fabio for all the help so far. Without Fabio I would not have been able to get this far.

I have checked the actual DP:4 status codes the Heat Pump gives when changing the status of the device (using the tuya app): (I have removed some clutter from below reporting to make it more readable)
➜ config node cloud.js
group: "Mijn huis .." device: "Weau_WP2" devDPS: "{ '1': true, '2': 32, '3': 247, '4': 'eco', '6': 0 }"
➜ config node cloud.js
group: "Mijn huis .." device: "Weau_WP2" devDPS: "{ '1': true, '2': 32, '3': 248, '4': 'hot', '6': 0 }"
➜ config node cloud.js
group: "Mijn huis .." device: "Weau_WP2" devDPS: "{ '1': true, '2': 27, '3': 247, '4': 'cold', '6': 0 }"
➜ config node cloud.js
group: "Mijn huis .." device: "Weau_WP2" devDPS: "{ '1': true, '2': 32, '3': 247, '4': 'auto', '6': 0 }"
➜ config
The DP codes for the 7kw Weau pump therefor are:
1: true, => true or false is power on/off
2: 32, => temp set
3: 247, => temp current
4: eco, => device operating state, this is either hot/eco/cold/auto
6: 0, => device fault codes, default 0 means ‘no error’
As can be seen, the DP 4: codes to be used are: “eco/hot/cold/auto”
In the Simple-Thermostat Card configuration I now have the following code:
type: custom:simple-thermostat
entity: climate.weau_wp2
layout:
step: column
mode:
headings: false
header: true
control:
hvac:
'off':
name: 'off'
heat:
name: Eco heat
auto:
name: null
and this gives the following result:
How do I get the ‘Card’ work with the right status codes the heat pump is reporting and also needs to change operating mode ?
Hi Fabio,
I found this page via Google as i am seeking a sollution for the same heat pump for Homey.
To share the knowledge, i will link (via my google drive) the communication commands for the heat pump i got once from the manufactor Weau - Heat pump communication commands and documentation
Maybe it helps your project…
Another question, are you able to help me with a sollution for the Homey?
Hi I have setup the weau, with the tuya local integration, works great!!
I cannot figure out how to go at this.
I’ve got the W’eau device setup in the Weau app.
It’s working.
Now following the youtube guide, i seem to have to link a device. But all screens are different on the developer portal. And i can’t seem to use the Weau app to add.
Is it really that difficult? Or am i missing something?
