@Tmaster What I meant by my previous comment was to tap on the Node name to see what sensors were connected - Had you clicked on TANQUE you would have seen a box pop up below giving you all the children to that particular Node with what value was last updated and when, so you could easily have found out all about your mysterious 13 children.
At least you have it sorted now, but it pays to do a bit of housekeeping in the sketch setup and Domoticz - eg which of the 6 "Unknown" Nodes is the one you want to next have a look at ?
All my Node IDs are set at the Node, and the sketch name labels the Node ID also, the Nodes are named in Domoticz for easy identification.
In the sketch my sensors are numbered sequentially and commented on what they are, so naming them in Domoticz becomes very much easier.

If you apply hot air it is easy to take off the white "double sided tape" and the plastic.
I see a lot of "!TSF" and "NACK" which seems to be radio communication problems.
That's MySensors related and can be related to many things, from soldering problem to power / capacitor issues.
In MY_DEBUG mode you should see your temp/hum printed on serial every ~15s so there is something wrong there, either wiring or a code issue.
Ty with the example included with the library "i2c_SI7021.h", without any MySensors related stuff, to see if your sensor is detected. You should see temp/hum on the serial.
@yoshi824 Most of us have been where you are now!
I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn.
If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.
