 *  - RotationSpeed → 0–100 % mapped to pump programs 1–4
 *
 * Program mapping (speed → program):
 *  1 – 25 %  → Program 1
 *  26 – 50 % → Program 2
 *  51 – 75 % → Program 3
 *  76 – 100% → Program 4
 *
 * Cloud API payload format:
 *  Start program N: { "zp{N}e10": "3" }
 *  Stop  program N: { "zp{N}e10": "2" }
