Hi,
Just migrated to Homey and I’ve tried connecting my two ProSmart PST50Ws. I’ve been ising them with the Smart Life app, but that’s not supported in Homey and now apparently Saswells apps does not work either.
Is there any way to get these conected to Homey?
Hi @Cheesy_P sorry for the late reply!
I am making a wild guess here!
If your unit has been working with Smart Life app, then your unit is programmed to communicate with the Tuya Servers.. Then my app wont work for you. Mine works only with the units that uses the “Thermostat” app and communicates directly to Saswell’s servers.
Thermostat on the App Store
Thermostat – Apper på Google Play
Unless you can make your units communicate with them then your out of luck.
You could try to reset it and install pair it with the Generic “Tuya” app in google/app store instead of SmartLife?
You might also see the difference by the different SSID it broadcast during pairing
“SmartLife-xxxx” - Means you need to use SmartLife or Tuya app. (Try both)
“Thermostat-xxxx” This one should be able to use my app.
Thank you so much for the reply!
After a lot of trial and error I figured it out (with a little help from Chatgpt).
You are correct that Tuya was the way to go. ProSmart had some outdated information in their site that sent me in the wrong direction.
I had ChatGPT make a step by step in case some one else winds up here with the same problem:
Step-by-Step: PST50W Thermostat → Tuya → Homey Pro
1. Go to Tuya IoT Platform.
2. Register and log in with a developer account (free).
–
2. Create a Cloud Project
1. Navigate to Cloud → Development → Cloud Projects → Create.
2. Fill in:
Project Type: Smart Home PaaS.
Data Center: select the one matching your Smart Life account region. For Norway (and most of Europe): Central Europe.
3. Click Create..
–
3. Authorize Required APIs
Inside your project:
1. Go to Project → API Services → Authorize.
2. Enable these services:
IoT Core
Authorization
Smart Home Scene Linkage
Device Status Notification
–
4. Link Your Smart Life Account
1. In your Cloud Project → Devices tab → Link Tuya App Account → Add App Account.
2. A QR code will appear.
3. Open Smart Life app on your phone → Me → Scan → scan the QR code.
4. Confirm.
5. Your Smart Life devices (including PST50W thermostat) should now appear in the project.
–
5. Get Access Keys
1. In the Cloud Project → Overview, copy:
Access ID (Client ID)
Access Secret (Client Secret)
2. Keep them safe; you will paste them into Homey.
–
6. Configure Tuya Cloud App in Homey
1. In Homey Pro → go to Apps → Install Tuya Cloud (by Jurgen Heine).
2. Open the app → Configure.
3. Fill in:
Business/App: choose Smart Life.
Country Code: your phone’s country code, e.g., 47 for Norway. (Just digits, no + or 00).
Username & Password: your Smart Life app login (email or phone + password).
API Mode: select Use Official Only.
Access ID/Secret: paste from Tuya IoT project.
4. Save.
–
7. Add the Thermostat in Homey
1. In Homey app → Add Device → Tuya Cloud.
2. Choose Thermostat (not Heater).
3. Select your PST50W thermostat.
4. Test by changing the set temperature and confirm it updates on the physical thermostat.
–
8. Troubleshooting
Error 1106 (permission deny) → either missing API authorizations or Smart Life account not properly linked.
No devices found → wrong data center. For Norway: Central Europe.
Login fails → ensure you use Smart Life credentials (not Tuya Developer account). If you used Google/Apple login originally, set a standalone Smart Life password.
No live updates → make sure Device Status Notification API is authorized.
Trial expired → in Tuya IoT, extend the free IoT Core trial under Cloud Services.
