How can I troubleshoot this synchronized disconnect/reconnect?

ESPHome

I’m looking for suggestions of how to increase the reliability of my ESPHome devices. They seem to be doing some synchronized dance where all four will disconnect and reconnect with a few seconds of each other. The interval between is inconsistent, sometimes 15 minutes, sometimes several hours. The devices are two Sonoff S31s, an ESP-12F relay board, and a KAUF bulb. While it usually just throws a bunch of garbage into the logbook, occasionally the disruption is enough to reset the uptime sensor I enabled on one of the S31s or to trigger the bulb’s “on power loss” behavior.

I’ve tried: setting static IPs, setting power_save_mode to “none”, setting output_power to “17”, shutting down the ESPHome LXC

Curious if your wifi is a single unit or a mesh wifi setup. I’ve had issue in the past with my wifi mesh causing issues with 2.4G devices.

Just a boring WiFi Router - tp-link Archer AX3200. DTIM is set to 1 and TWT is turned off. I’ve seen some mention of channels for troubleshooting similar issues, but I don’t seem to have any related options.

One of the S31s is plugged in less than a foot away from it, and the relay board is in the garage about as far as it can be while under the same roof.
