Dennis,
The following is copied from Ken Bauer’s website:

“Basic System Specs
– Radio Frequency: 902 – 928 MHz IMS license free band. Each system is preset to a unique channel
within this band and also is programmed with a unique digital code.
– Range: 5 km or more line of sight typical, but varies with installation and conditions.
– Response time: up to 1 second delay from transmitter activation to DT.
– Compatible with all Red Magic (RMT, RMT2) and Smart Magic (SMT) timers.”
So you see there is a insignificant chance of interference.
I recommend Ken’s products and suggest you read his info carefully.
