I currently have a Vantage Pro2 Plus and a Wifi Logger 1. It has worked pretty reliably over the past few years. I just noticed there is a new version out. What are the differences between the two? The website doesn't have a comparison.
I have exchange main chip to ESP32 from ESP8266.
I still cant say if it was right. ESP8266 was marked as old when I have release WiFiLogger.
ESP8266 has more mature libraries. It is much easier to repair bugs in libraries etc.
ESP32 works on RTOS (Real Time Operating System) and on 2 cores. Reparing bugs in libraries it comes down to crying and waiting for a new lib release.
On the other hand ESP32 is better and has a future ahead of him.
WiFiLogger2 has also external watchdog chip. I think first WFL2 was without it, then all have it.
It is special chip which is monitoring working of ESP32 and reboot if it is necessary. Is has interval time about 3 minutes. So this 3 minutes should be maximum when WiFiLogger2 is out of order.
WatchDog chip is because I had feedback info from my client who said that he was needed to reboot WiFiLogger1 twice during the year. He is still happy with it, but I was able to make it better.
