Network priority

Hello,

I am about to build my first ESPHome node in the hope it will solve a problem I have with both MySensors WiFi gateway and Tasmota. The node is to be placed in my garage where I also have an AP. But, sometimes (a couple of times per year) I have a power outage in the garage, and then the Tasmota switch, and the MySensors gateway is faster booting than my AP when the power returns. This means that they will connect to an AP in my house instead, with very weak signal. All AP have the same SSID, but they also have individual SSID.

The question I have is if multiple networks with priority will help me in this case?

If I add to networks “GARAGE” and “ALL_AP” to the configuration, and gives “GARAGE” priority: 2.5, will this mean that the node will first give it 3 attempts to connect to the garage specific SSID before trying to connect to thee SSID shared by all AP’s?
And, if so, how long time is there between the attempts?
