@MrPinrel,

Short Answer: Yes, You should have no problem using a lesser deco node as a satellite node, as the features of the network are mainly determined by your main node and all of our Decos are meant to work together to provide easy upgrade paths.

It is worth noting if you have done a lot of configuring and tweaking in the Deco app that there are a few features, such as node selection, that require each node to be compatible with the feature. If you use these features on your network now, I would recommend being careful to not choose an extremely old model that may not have received the 1.6.0 firmware yet, however the firmware is being rolled out to more and more models each week.

In general, you will not see any decrease in your network performance but will be limited to the speeds of the satellite node. A lesser node would only become a bottleneck if attempting to daisy chain deco connections through it, for this reason, I wouldn't put it in the middle of your home, but for your case it would work perfectly.
