@nagelc This seems to me the proper way to do it. Presentation of data on web/app should not modify the actual data from the node itself. For now HA is a no go for me until I get a chance to look at the HA mysensors code to see what it is doing.

So, got my ESP8266 and set it up as the ethernet gateway. Removed the on-board RPi gateway. Domoticz picked up the new gateway easily enough (this has never been an issue). Now, turned on my nodes (with static nodeIDs) and the gateway picked up one of the two nodes (why? no idea). Sent presentation to gateway then to Domoticz. Domoticz sees the humidity sensor as S_UNKNOWN but with V_HUM values???? I have no idea what is happening. The ESP gateway log shows the sensor as S_HUMIDITY just fine. So, this is a new wrinkle. But the same issue persists - temp/hum updated on the Hardware view of the gateway but Device view of that sensor is never updated from initial state. I am this close to taking the whole system out back with a baseball bat. So, status now: Only 1 of 2 nodes seen by gateway (unique IDs on both) The 1 node values are sent to gateway around every 5 minutes (with new values as tested over night) Domoticz does not update the Device with any new values from initially seen data Gateway serial log is showing updates just fine MYScontroler running on my Windows box also sees the updates just fine OpenHab2 does not see any updated from initially seen data Stress level at 100%

@TheoL No damage. Water went up about 7 feet on our lake but had another 11 feet to go to threaten our property. Biggest flooding was to the south of us. We did have a fun time hiding out in our laundry room during tornado flying up to the east of us. Also, I do not think the radio is dead - hooked it by accident to my Uno testing board and it was transmitting just fine. Love these things - very tough.

@korttoma Success! Got this ethernet gateway up and running! Thank you very much.
