CHAPTER 26
Troubleshooting
26.1 Network and access
| Symptom | What to do |
|---|---|
| Green LED blinking non-stop | The Wi-Fi setup was not completed or the password is wrong. Redo Chapter 8, double-checking the password |
| Green LED off | The equipment lost the network — it retries every 1 minute. Check that the router is up and the signal at the spot |
| Blue LED off (no internet) | Local control keeps working. Without internet there are no e-mails, no cloud and no app away from home. Check the router's connection |
| The network does not appear in the setup list | Signal too weak where the equipment sits (the cut-off is −75 dBm), or a 5 GHz network. Move the router closer or enable the 2.4 GHz network |
| The equipment keeps dropping off the network | Fix the router's channel at 20 MHz (B/G/N mode), avoid mixed channel-width mode, and check the signal in System → System Status → Network |
| The IP changed and I lost access | Check the router's device list, or the app's System screen. Then reserve the IP on the router by the MAC address |
| No access through the app, but the Local Manager works | System → System Status → Network: check Internet, MQTT and the last cloud sync |
26.2 Outlets and Powerbar
| Symptom | What to do |
|---|---|
| Outlets showing "Not Detected" | The Powerbar is not responding: check the network cable in the BUS port, the bar's power supply and the A/B switch |
| Both Powerbars show the same state | The address switches are on the same letter. One must be on A, the other on B |
| An outlet does not obey a rule | Look at the rule's status (Conflict?) and the outlet's mode — in manual mode, rules do not act. Check the rule order too |
| An outlet turned back on by itself after I switched it off | The system returned to automatic — through the Time Limit in Manual Mode — and the outlet's mode took over. That is the configured behaviour |
| Nothing turns on and the system refuses commands | Check the padlock (protected mode) and whether there was an Emergency Stop — in that case, Power → ALL AUTO restores it |
26.3 Sensors and dosers
| Symptom | What to do |
|---|---|
| A sensor with an unstable reading | Move the sensor cable away from power cables; check the connector; on probes, check the age and redo the calibration |
| Sensor "Not Detected" | Check the connection on the correct port. BUS modules are detected at start-up: restart the equipment after connecting |
| A sensor alert with the value "-" | A missing reading: a communication failure or a faulty sensor — it is not a water problem |
| A doser does not dose | Check, in this order: Disabled mode? Not calibrated? Reservoir insufficient? Are 3 dosers already running? System locked? |
| An inaccurate dose | Recalibrate (Chapter 21) and check for bubbles and the hose length |
| Empty graphs | System → System Status: check SD and FS in the Controller block. The history lives on the memory card |
26.4 If nothing solves it
Talk to support (Chapter 29) with the equipment's UUID at hand and, if possible, a screenshot of the System Status screen. In many cases we can diagnose remotely.
