Prevent unnecessary writes

[amarcolini]

I'm aware of PhotonFTC's asynchronous read capabilities, which help cut down on calling reads too often / unnecessarily. I think a great feature addition would be adding the same capabilities for writes. This could come in the form of:

• Having the ability to set a write frequency for certain hardware devices. Writes would be called normally, but they would actually only be sent per the desired frequency.
• The same as above, but instead of a frequency, PhotonFTC could use a tolerance (e.g., if the called write is different enough from the last issued write, then it would be sent).
• A mixture of both.

I'm also available to contribute on this.
