Use of Wild Cards to search channels

We operate roughly 600 data loggers on Think Speak where there are roughly 150 gateways and each gateway communicates with a node. Our channels are labeled node# - gateway number and each number is 16 diigits. We have not found a wildcard search function so must have each number exactly right or we cannot find our channel. In some cases we wish to query a gateway and see which nodes are successfully communicating with it.

My simulink program require a feedback loop from an AC signal. How does one create a mean/ median value from a sinusoidal signal. Specifically, I want to average a power signal for last 0.1 sec and then adjust PWM signal.

Regarding Recent Spam Attacks

Over the past several months our communities have been the target of ongoing spam attacks. Spam is a common issue online and spam prevention is something we include as part of our standard development processes. The most recent attempts appear to be specifically targeting our sites with a combination of manual and automated attacks, probing with a variety of content attempting to bypass our filters. Regrettably, the attacks sometimes make it through our defenses, cluttering your inboxes and the content in our communities.

Rest assured, we are dedicated to continuing to evolve our tools and improve our capabilities to meet the goal of eliminating all spam in our communities. We appreciate your patience and understanding as we work to get there.

Sincerely,

David Wey
