202U - How many can there be in close range?

I’m using the 202U with multiple 202Us in a backyard area. What is the limit of the number of transmitter/receiver pairs can there be in this limited area? Thanks

It depends on how you use the remotes.

Since all remotes transmitting at same 433mhz frequency (they do have different codes, but on same frequency), so if multiple remotes are transmitting at the same time, only one / or none would work.

If you only use one remote at a time (for example, use remote A for a second, then use B for a second), then there is no limit how many can be in close range, because all our remotes have different codes, and receiver only respond to programmed remote (codes).
