Recommendation for WiFi relay

Hardware
1

I built my system using ESP8266 + ESP-01 with ESPHome.
Only code for defining a switch was added in yaml, but ESP8266 devices frequently became unavailable.
Sometimes the device was even frozen.
No response at all
I believe that it is a hardware problem.

Is there any WiFi relay (with NC/NO) that is reliable?
The maximum load is less than 3W (20VAC).

Devices designed by LC Technology typically use an ESP-01 or ESP-12 module with 10A relays (1, 2, 4, 8 channels). They are available on Amazon, aliexpress, and other vendors.
