Hi everyone!
I have run into a problem with showing temperatures picked up by 10x Dallas DS18B20 temp probes, connected to a NodeMCU V3-module ESP8266 ESP-12F.
Before, I had no problem displaying the temperatures in the HA GUI and it worked just fine, suddenly the entities just shows as unavailable, without any changes made by me (that I know of…)
Strange thing is that they are detected and reports temperature just fine in the ESPHome add-on dashboard.
Only thing I can think of is that the reception isn’t great since the board is placed in the basement, but it has worked flawlessely before. The connection seems to go down once in a while in the ESPHome dashboard (at least it’s sometimes listed as offline, but always revert to online when opening logs).
Anyone facing the same problem? I would really appreciate some help along the way! 
In the GUI:
