Shelly H&T Plus Gen 2 intermittently unavailable in 2024.5.x

The problem

I started using four Shelly H&T Plus Gen 2 under Home Assistant 2025.5.3. Each Shelly H&T independently was displayed as unavailable very 15-30 minutes for 15-30 minutes. Typically, two of the four were unavailable at any moment.
As a workaround, I restored back to 2024.4 and configure the four Shelly H&T. (They were not in use in that backup.) All four Shelly H&T have consistently reported their readings in Home Assistant since.
I am running Home Assistant in virtual machine on a Synology NAS. The IP address of each Shelly H&T has been reserved in my home router. The LAN is a simple 192.168.1.2 - 192.168.1.255 range. The Shelly H&T Plus have up to date firmware (20240425-141825/1.3.0-ga3fdd3d).
