 ## Attention
 
-1. The program is written for and tested only on [LILYGO T-ETH-Lite ESP32](https://github.com/Xinyuan-LilyGO/LilyGO-T-ETH-Series). To work on another module it will be necessary change ZH_LAN_MODULE_TYPE and ZH_LAN_MODULE_POWER_PIN (for using LAN connection only). No changes are required when using a WiFi connection.
+1. The program is tested on [LILYGO T-ETH-Lite ESP32](https://github.com/Xinyuan-LilyGO/LilyGO-T-ETH-Series) and [Wireless-Tag WT32-ETH01](https://github.com/ldijkman/WT32-ETH01-LAN-8720-RJ45-). To work on another module it will be necessary change ZH_LAN_MODULE_TYPE and ZH_LAN_MODULE_POWER_PIN (for using LAN connection only). No changes are required when using a WiFi connection.
 2. If using a WiFi connection, the WiFi router must be set to the same channel as ESP-NOW.
 3. Only one device can be updated via ESP-NOW at a time. During the device upgrade, there may be delays in the response of others devices on the network.
 4. The certificate (certificate.pem) must match the upgrade server.
