Raspberry Pi 3 Model B for openHAB 3.0

HI I had a raspberry pi 3b running 2.5 and have recently upgraded to OH3. All worked fine but I had a power outage that corrupted the SD card and reset all my tasmota devices. It was a nightmare to get back and as it controlled the heating and all the lights. The WAF ( wife acceptablilty factor ) was rapidly diminished. This was because the house power clicked on and off many times in succession during the night. I did not realsie that there was a setting in the Tasmota devices that allowed then to rest to factor on rapid power cycling!. That is fixed now.
For the WAF improvements I have now fitted a UPS and added a second Pi B that I had lying around and switched both to boot off SSD drives removing the SD cards completely. It now has 1 dedicated to openhab and the other runs the MQTT server, and Graphana and Influx db. This also allows me to use the backup system on one to back up to the other. Real belts and braces but increasing the WAF was a imperative! It is now up for 100+ days and has survived a couple of power events.
