C++ source, HTML, Javascript & JSON format.
- MQTT transmission of data each hour,
- log history each hour in flash memory,
- adjustment (setting.h) of the unit of diffusion,
- retention of records on system time synchronization defect and re-indexing on synchronization recovery before historization,
- monitoring of the consumption for detection of possible leaks in the water network,
- configuration of the monitoring parameters via the Web interface,
- MQTT alerts about possible leaks to the home automation device (Domotics, Jeedom, ...).
- 3 configurable SSID,
- web interface configuration,
- definition of IPs (such as the reverse proxy) excluded from configuration changes; allows secure exposure of the (only) home page to the Internet,
- debug trace available by telnet console (#ifdef DEBUG),
- firmware update via WiFi, without loss of data or setting,
- accepts HTML commands from the home automation software: current counter value, log history recovery in JSON format, clear current history, backup of current measures with reboot, ...
- modem sleep option allowed between measures...
- connection to pulse sensor (open collector or dry contact): 3.3v/5mA, bounce filtering.
Http requests available (except from EXCLUDED_IPV4_FROM_TUNE):
| http://IPAddress | WEB User Interface |
| http://IPAddress/getCurrentIndex | current counter value |
| http://IPAddress/getData | data file - all measures saved [Unix date, counter index] |
| http://IPAddress/getCurrentRecords | not yet indexed measures (on NTP error) |
| http://IPAddress/resetHistory | current data file will be erased after DELETEDATAFILE_DELAY (ms) |
| http://IPAddress/modemSleepAllowed | UI available during AWAKETIME (s) before and after each hour (minimum power consumption) |
| http://IPAddress/modemSleepDenied | WiFi always connected and UI always available (maximum power consumption) |
