* Corrected an issue with the logging that could result in logging issues.
* Removed some of the logging entries for successful events like Weather updates, Real Time Clock updates etc.
* Correct a bug related to buffer sizing that could cause instabilities.
* Added Data Fields for Average Monthly High Temperature values to the System Settings page replacing the single Baseline value. Now adjustments will be correct for each month of the year. Data for your location can be obtained from Weather Underground or other sources to input the Monthly Average High temps. We are looking to automate this data download in a future release. The mobile app will be updated to support editing these fields in a coming release.

Both Wired and WiFi Versions 2.00.01
* Insteon Event processing improvements.
* Corrected labels for the Days of the week for the Temperature values when viewed on the Mobile App Weather Tab are incorrect and duplicated days appear.
* Improvements to the NOAA weather processor. There was a condition that could potentially stall the thread preventing further updates.
* Updated the text that is displayed for Open/Close sensors to show "Open" or "Close" on the web and mobile app similar to the I/O lincs status.

Both Wired and WiFi Versions 2.00.00
* Added Insteon Scene programming to allow controlling numerous devices at the single press of a button.
* Added Watering Scene programming to allow custom watering schedules based on day of month, time of day, unlimited start times and more.
* Added NOAA Forecast data to allow preemptive Rain delay enabling based on the percent chance of rain in the coming days. (User defined level and days to look forward)
* Added Watering Run Time adjustments based on daily forecast temperatures. If enabled you can create a stepped or linear adjustment based on a baseline temperature value. This will increase or reduce watering based on the values entered. A simple Excel spreadsheet with graph and user entered fields can be downloaded using the link below to enter your with the values and see the results.
* Added Insteon Thermostat programs page to allow multiple Thermostat programs setting temperature, mode, time of day etc.
* Added Insteon Scene programs page to allow the scheduling of Scene programs you have created.
* Added Insteon Events programs page to allow external Insteon events to trigger Scene programs you have created.
* Added Mobile App Push Notification option to Insteon Events and Rain Delay Events. If selected HydroFLASH sends your mobile app a notification when any of the selected events you choose occur. The settings for these are on the System Settings page (Rain Delay push notifications) and on the Event Programs page (for each event). You also need to enable the push notifications option on your HydroFLASH mobile device under your Controller Edit Menu. (Currently Android Only, iPhone update will be coming soon)
* Watering Scheduler now runs internally at a 1 second resolution. Program Times are entered just as before in Hours:Minutes so no changes are needed to your watering programs. What this does provide is the ability to have HydroFLASH increase or decrease the run time by small amounts based on the temperature adjustments if enabled. Additionally the Monthly percentage values that are applied will effectively reduce watering in meaningful amounts for stations with short run times. For example, stations that are set to a 1 minute run time with a 50% reduction will only run for 30 seconds. Previously there was a 1 minute minimum and the percent adjustment had little or no effect on stations with short run times.
* Added Insteon logging option on System Settings page. Keeps log file from filling up in the event a device goes off line. Only enable if you are actively diagnosing a Insteon communication issue.
* Watering Program End Times are now calculated and displayed regardless of having the Start Time Enabled check box checked or not. This is for referencing the End Time value if using a Watering Scene macro to create a schedule so you can schedule the correct times for repeated Watering Scenes.
* Added Manual Scene control to the Manual Insteon web page to allow manual activation of scenes.
* Added Scene Edit page to the Insteon Programs page to allow the creation, editing and deleting of Scene macros. Simple interface to allow editing and management of Scene macros. Will be adding this to the Mobile app soon.
* Simplified the Wireless setting page, eliminating some settings that were not needed. WPA2 and WPA-Personal (WPA-PSK) are functionally under the same menu selection. Updating to this version should not require you to change any settings on your Wireless version.
* Updated Wireless driver. We need feedback on this as we have had some of you have issues with HydroFLASH disconnecting from your network after extended time periods, while all other features working correctly. There have been other improvements in the lower level kernel components that fixed other issues that may have been related to this issue so again feedback is needed if there are any noticeable improvements (or issues) when using the updated software.
* Updated the File Management to allow moving up and down the directory structures with the additional option of being able to select individual files for deletion. (Careful here as you can delete your program, scene or other files). This is more of an maintenance feature should you need it.
* Cleaned up the System Settings page adding headers to group similar settings and some help information.
* Cleaned up the Status page placing METAR data in framed box and added NOAA Forecast Data with Probability of Precipitation and Forecast High and Low temperature values.
* Added a link on the Status page to the NOAA weather site to provide a look at additional weather information.
* Daily METAR Temperatures (High and Low Values) are also collected and stored for the previous 7 days and are used as a backup to the NOAA temperature data should it not be available.
* METAR Hourly Rainfall amounts are now tracked for a 24 hour period vs the previous 12 hour period and stored in the event of a power cycle.
* Added information to the Status page indicating the currently calculated Watering Time Adjustment percentage.
* Added Weekly Temperature data to Mobile App Weather Display under the More Tab.
* Fixed a display issue with the temperature data on the main Status page.
* Added link on the settings page to the Excel Watering vs Temperature file for downloading.
* Added link on main status page to the forum.
* Updated the User Manual.

Both Wired and WiFi Versions 1.01.49
* Added 12 hour Precipitation totals and triggering rain delay based on a user entered value on the System Settings page. Also added a check box to only use the 12 hour precipitation data in the METAR as a rain delay event trigger if desired, otherwise it will use any METAR data rain trigger. Trigger level is variable in .01" of rain in the last 12 hour window.
* Updated Mobile App interface to support most of the System Settings previously only available via the Web Interface. Requires Mobile App update, Android will be available via the play store shortly and iPhone will take a few days to be available due to the Apple approval process. We will announce when both are available via a Forum email / post.
* Added SNTP restart flag to restart / re-lookup server IP addresses in the event the SNTP server returns a time out. This seems to occur on rare occasions when a server from the pool goes off line or other error. Restarting will get a new set of address from the pool.
* Changed HW reset button to 3 seconds vs 10.
* Added world time zones.

Both Wired and WiFi Versions 1.01.48
* Modified the default hardware reset value for the 'Wireless Frequency Band' to use B or G vs ALL to so that HydroFLASH will always fall back to those modes following a hardware reset. This addresses an issue where some routers loose network connectivity with HydroFLASH locally or via cloud, or fail to communicate with specific N type routers (Latest Airport Extreme's and Airport Express Extenders have exhibited this issue along with others).
This issue and appears to be strictly related to the N mode operation based on our testing. We are now looking into the root cause and will advise.
For users that are having any connectivity issues please go to the System Settings page on HydroFLASH ensure that the Frequency Band selection option is set to "BG" as this is the recommend setting. Updating your firmware to this version will NOT automatically change your selection. It only ensures that if you were to reset the device it would default to that mode.
* Updated the SNTP server (Time Server) process so that if DNS is not available at power up, HydroFLASH will continue retrying periodically to acquire name service and then start up the SNTP servers. This will ensure that your RTC (Real Time CLock) is correctly updated.
* Minor change to the METAR retry logic to improve performance.

Both Wired and WiFi Versions 1.01.47
* Eliminated Requirement to change your SSID to HydroFLASH when setting up HF to join your network. HF will now join any open network it finds following a reset.
* Fixed Bug that would corrupt your Config Files (Watering stations, Insteon Devices, User Settings, etc) when changing login password or network settings.
* Adds Odd and Even Watering Days option to Settings. Allows setting Odd/Even/Any Day on a station by station basis so that drip system can be run any day (local ordinance dependent).
* Added Insteon Modem detection at start up and add info to log file.
* Modified wireless settings to enable TKIP+AES when setting WPA2 Mixed Mode from web page. This should now allow correct operation of WPA2.
* Changed layout on settings page to have station and monthly watering options side by side.
* Added Real Time Clock Test at power up.
* Added new LCD display to indicate Cloud status, Connected , Polling, or Connect Error and added it to the main Web Status page.
* Added 2 repeat download attempts for METAR download in the event there was a failure to connect to the NOAA servers.
* Added local IP address to Log file Header.
* Updated User Manual
Note: After installing this update following the reboot of HydroFLASH, go to the System Settings page and click the Save Settings button once to update your system settings file.

Both Wired and WiFi Versions 1.01.46
* Modified File System behavior to eliminate potential loss of user settings when making network config changes.
