@GLAB You can set the frequencies using the settings in MyConfig.h, which is in the MySensors folder. If you put any of the defines from MyConfig.h into your sketch, they will override the MyConfig.h setting for that sketch only. If you are using the RF24 radio, there are different channels which correspond to a given frequency. The default is channel 76. There is a list of typical channels in MyConfig.h. If you want to change the channel for all the sketches, change it in MyConfig.h. If you want to change it just for the sketch, add a define to the sketch. For example: #define MY_RF24_CHANNEL (84) The problem with changing the channel in a sketch is that the gateway has to be on the same channel to receive from the node. So, normally it makes sense to change in MyConfig.h because you usually want the gateway and all the nodes on the same channel. Other radio's like the RFM69 list the frequency instead of using a channel. They can be overridden in the sketch as well. You can find the defines that are needed in MyConfig.h

Related: https://github.com/mysensors/MySensors/issues/1516 The best way is probably to replace the TinyGSM folder in MySensors with the latest upstream version try to upload the sketch and see what breaks Troubleshoot and fix all errors found go back to step 2 for all supported boards and configuration options upstream any necessary changes

@NielBierman Why are you using VARs when there are already moisture and temperature categories available to you? Just give each temp and moisture sensor a unique CHILD_ID (simply by adding 1-8 in the name) and you are done!

In general, yes, the MySensors framework (library?) should support FOTA a couple different ways (read more at link). Were you aware of this, or is there some problem with your particular hardware? @NielBierman said in FOTA possibilities for remote sensor network: Raspberry pi I don't know yet whether you even need to change your gateway from microcontroller (uC) to Single Board Computer (SBC) or not. However if you do (or are looking for a controller, or whatever), by all means, please do yourself (and all of us) a favor and do a little more research as there are lots of better options out there for SBC nowadays, than RPi! For me, uC have been fine for gateway although I do use some SBC for controllers, MQTT broker, and various other GNU/Linux based servers/services and they are wonderful for that. But perhaps your needs are different from mine.
