@Newzwaver the wiring is pretty straight forward following the above links for the transistors and display. I will try to post a wiring scheme, but that like can't happen within the next two weeks for time constrains. As for the parts list: Arduino nano I2C display, such as the 20x4 character display described here: https://www.mysensors.org/build/display 1 or 2 transistors, I have used the Maverick PR-022 which meanwhile I learned are made of Semiech's 105GT-2 (datasheet: https://www.rapidonline.com/pdf/61-0442.pdf) 1 or 2 resistors matching your thermistor's nominal resistance (for the above: 1 MOhm) The wiring for each of the thermistors and the display is independent of each other following the above guidelines and you can use either one or two thermistors. The display is optional, too. Hope this helps for now. I will post diagrams when I have a chance...

o.k., quick update... contrary to what I reported yesterday, it now looks like my gateway is getting sensor readings from the node in question at irregular intervals. strangely enough, when I connect my Mac and launch the serial monitor, the sensor printout still stops after just the few lines above. Has anybody ever experienced something like this before? Still need to do the hardware swapping to see if this is related to a malfunction of any of the components.

thanks, it works - in principle! I'm using smartSleep in my sketches and that causes the nodes to send heartbeat signals, which is o.k. But can it be, that the request for presentation is only received and responded to by the nodes when the node has sent a heartbeat? When I receive a regular sensor reading and fire back a presentation request, the node doesn't seem to care...?!

I have not, but will now thanks!
