True, but this is MUCH less of a problem with IQ compared to M-Series. I just installed 212 IQ micros on a building with 268 existing M-Series. The M-series required ferrite rings and the IQ worked flawlessly without any filtering (although it took about 3 hours for all of the IQ micros to initially come alive initially). This is a grocery with a lot of noise / motor loads.
