Relay switch with remote: use correct product id.

Expose inching control (experimentally)

- value is base64 encoded, seems to be always 4 char long
  (3 bytes after decoding) despite docs saying up to 255 char
- First byte is enable/disable switch, either 0 or 1.
- Second and third bytes seem to be number of seconds.
- Range unknown, but enabled up to 1 hour.  Max is 65535s if
  bytes do not extend further, which is short of 1 day, but
  long enough to represent 12 hours.
