@chbla said in Multiple uses battery RFM69 node:
Can anyone suggest a source for the parts? Are there any sources that you can upload the files by any chance?
If you mean can you upload a BOM to a company and then it generates a basket of the items, then i know that farnell and maybe digikey do this. But i only use this feature that is built into EAGLE pcb designer, so i'm not sure if they support it directly on their websites, might be worth a look.

@ozrex,
I don't want to assume your knowledge level. However the truth is that you will probably need to put together different bits and pieces from various threads in order to come up with your own custom solution (the A/C interface (IR) part, the battery part, etc...).
Maybe it is worth it to create your own new thread, or maybe you want to keep researching / trying on your own a little longer first. The latter is admirable, and is the way I usually do it, too. Some times to a fault in my own case. Don't suffer along in silence if you are struggling to find the information, make a thread instead. If it becomes too difficult you may give up. We all need some small successes along the way to keep motivated and keep it fun.
Probably best to create a new thread (I don't want to derail this one too much) but something you might want to look into is OpenMQTTGateway. I use it for my 433mhz, but it also supports RF, BLE, LoRa (and perhaps others in future) all on the same gateway! To me that was the way to go... And so far has been flawless for me.

The 85 reading is actually an error message used by the ds18b20 to indicate it has not had time to complete the processing of the reading. Most commonly this is only seen when the node first boots up and can be ignored or fixed by adding a small delay. You will find a lot of information on this if you do a google search. I have never experienced it myself but from other posts on the net it seems power supply problems and long cable runs to the sensor can also cause the error. Some have also had success by using a different resistor value. Note you only need one resistor fitted near your nodemcu not a resistor at each ds18b20.
If the 85 reading is well outside your expected reading you could just filter out any readings over 84 as well.
