Mounting space, power, Wi-Fi, wash signals, and plumbing to have ready.
Have these ready before install day.
| Mounting space | A wall or rack near the chemicals, out of direct spray, with room to open both pump heads. |
|---|---|
| Power | A standard outlet near the device. One power supply runs two Doza units. |
| Wi-Fi | 2.4 GHz Wi-Fi with internet at the mounting spot. Guest networks with a sign-in page don’t work. |
| Wash signals | A controller output for each chemical function, 24–120 V AC or DC when on. |
| Plumbing | For each chemical: a container, suction and delivery tubing, and an injection point on the wash line. |
| Calibration | A measuring cup, graduated cylinder, or digital scale. |
| Account | A DozaLink organization with an active subscription and the site added as a location. |
Check the Wi-Fi signal
Stand where the device will be mounted and check the 2.4 GHz signal on a phone. If it is weaker than −80 dBm, improve coverage before installing, for example with an extender, mesh node, or outdoor access point.
On iPhone, turn on the Wi-Fi scanner in Apple’s AirPort Utility (Settings → AirPort Utility). On Android, an app such as WiFiman shows signal strength. The numbers are negative: −65 is stronger than −80.
No Wi-Fi at all? Doza can run local-only, without remote changes, reports, or updates.
