There are a number of places that the Peplink Balance One (and I assume other Balance products) take a static number where I really need a schedule.
For each WAN connection I can specify download and upload speeds. However, neither of my ISPs comes anywhere near their rated throughput on a regular basis. I might see the rated performance at 4AM, but only 70% of it during daytime off-peak periods and 30% during evening peak. This is particularly true of my lower-latency fixed wireless ISP. My other ISP is Hughesnet, so I always have high latencies. But it has more predictable throughput. Unfortunately it is metered. The combination makes it very difficult to create the right rule-set. However, if I could apply different speeds during different times of day it would be easy to create a rule-set to balance all these factors.
I already mentioned Hughesnet, and the ability to managed the metered connection is one of my favorite features of the Balance One. However you have no provision to deal with the bonus data available between 2AM and 8AM. Other satellite providers offer their own off-peak extra quotas (or no quotas off-peak). So it would be nice to specify schedules here as well!
