Make Tuya Smart Home Devices Local (no cloud)

Tuya smart home devices are popular because they’re affordable and easy to set up. The downside is that they depend on Tuya’s cloud servers to work. That means if your internet goes down, or if there are server issues, your devices will stop working. 

The good news is that with some configuration changes, you can make many Tuya devices work locally. Improving privacy,  reliability, speed up response times, and gives you full local control over your smart home.

Why Make Tuya Local

• Reliability: local devices keep working even if your internet is down or the Tuya servers are unavailable.
• Speed: commands don’t need to travel to the cloud and back. Everything happens locally on your home network
• Privacy: Its very possible that your smart home device data will go to untrusted cloud servers in China and there if no of knowing for sure how secure your data is. With Tuya devices running locally, no data leaves your home network.
• Integration: Link with platforms like Home Assistant.

Ways to Make Tuya Local

There are a number of different ways to make Tuya smart devices local smart home devices. All of the solutions listed below have some drawbacks, so research each one to see which is most suitable for your requirements.

Home Assistant Tuya Local Integration

This method is the most popular as it allows the the greatest compatibility and functionality to run Tuya locally

• Install Home Assistant on a Raspberry Pi, PC, or NAS.
• Add the Tuya Local integration via HACS (Home Assistant Community Store).
• Connects directly to devices without using Tuya’s servers.
• Time required: 30 to 60 minutes depending on experience.

Flashing Firmware with Tasmota or ESPHome

• Works with many Wi-Fi based Tuya plugs, switches, and bulbs, but not all.
• Requires opening the device or using over the air tools like Tuya Convert (if still supported).
• Once flashed, devices work entirely locally and integrate with Home Assistant, MQTT, or other hubs.
• Time required: 1 to 2 hours per device first time.

Use a Local Hub or Gateway

• Some Zigbee or Bluetooth Tuya devices can pair with a local hub (e.g., Zigbee2MQTT or Zigbee USB stick).
• Devices connect to your hub, not Tuya’s cloud.
• Integrates neatly into local systems like Home Assistant.
• Time required: 1 to 2 hours for initial setup, minutes to add new devices.

Use the Official LAN Mode (Limited)

• Applies to some supported lights and plugs.
• Enable in the Tuya Smart or Smart Life app.
• Still requires cloud for setup and some features.
• Time required: 10 minutes per device.

Things to Keep in Mind

• Warranty – Flashing firmware usually voids it.
• Compatibility – Not all Tuya devices can run local firmware.
• Updates – Local devices won’t get Tuya app updates
• Backup – Note down configurations before making changes.

How Much Time Does It Take to Maintain a Local Tuya Setup

• Basic LAN mode: Minimal upkeep, a few minutes every few months.
• Home Assistant integration: About 1 to 2 hours a year for updates and tweaks.
• Flashed devices: Little to no maintenance once set up, though initial flashing takes longer.

Final Thoughts

Making Tuya devices local isn’t just for tech enthusiasts. A simple step like enabling LAN control or using a Zigbee hub can make your smart home faster and more reliable. For those who want full control, flashing to Tasmota or ESPHome puts you in control, without depending on Tuya’s cloud servers.
