Any interference issues with a c4 next to a c7?

Just picked up a c7 to add to the c4.. and I'm probably going to run both for a while with radios active.. I am planning on putting the two right next to each other. Are there any z-wave or ZigBee interference issues with the two being right next to each other?

Logic says yes, experience tells me no. I have had four hubs on different channels right next to each other (inches apart) for years without a problem. YYMV.

The key is to run them on different Zigbee channels. I have two hubs. One runs on channel 20 and the second one runs on channel 25. Z-Wave does not have an option to change channels, so it must not be an issue there. Also, I have my WiFi 2.4 GHz channel set to channel 1 to keep WiFi and Zigbee as far apart as possible.

I have a C5 and C7 next to each other, both on the same zigbee channel and have had no issues (as far as I know…)

I had a C4 next to a C7, never had any interference issues. But it didn't take me long to decide to retire the C4 for another C7.
