I installed 2.2.1 rev0 in my OS 2.3, after a hard reset and followed by another hard reset.
The email notification settings are not visible (app 2.4.1 both on PC and Android).
Do they work for OS 2.3 ?

[Nicola]

What about OS 2.3, has its timeout also been reduced to 5ms ?

[Nicola]

Now it all makes sense, thank you!
And if one wanted to modify the UI, I see that the repo can be cloned and run locally, is that the way to do it?
And next one could host his own modified UI somewhere else and change the firmware to redirect to an alternate address?

Thanks!

So it’s clear, too many pulses and the flow count (2582 in my example?) is or may be off. I will experiment with a 10 to 1 frequency divider.
But what about the math:

First email: “Station XYZ closed. It ran for 2 minutes 0 seconds. Flow rate: 1363.91”
Second email: “Flow count: 2852, volume: 85.56”

Whether 2852 is wrong or not, where are 85.56 and 1363.91 coming from? Irrigation time was 120 seconds.

[Nicola]

Also: I understand OS may miscount the pulses from the sensor, but once it gets that figure, right or wrong it may be, the rest of the math should add up.
If my sensor really does (per datasheet) 50 pulses / sec when the flow is 100 l/min, the “Flow Pulse Rate” parameter to configure in OS UI should be: (100/60) L /sec = 50 pulses –> 1.67 L = 50 pulses –> 0.033 L/pulse; the UI allows 0.03 and 0.04, so I set it at 0.03 L/pulse. From practical testing, monitoring the level of the reservoir, I figured that the correct figure was somewhere between 0.03 and 0.04 so close.

I then irrigated 120 seconds, and from IFTT I get two emails at the end of cycle:

First email: “Station XYZ closed. It ran for 2 minutes 0 seconds. Flow rate: 1363.91”
Second email: “Flow count: 2852, volume: 85.56”

My OS is set to Metric. What’s the unit of measurements of these three figures?

From the flow count = 2582, as it run for 120 seconds, the sensor was giving 21.5 pulses/second. I presume all the calculation start from 2582, right or wrong it may be, so now:
1) Since I set 0.03 L/pulse, 2582 * 0.03 = 77.46 L total: why is volume showing as 85.56? The math just does not ads up..?
2) What’s the unit of measure of the flow rate? L/hr? L/what? Still gallons? Because if I take for granted 85.56 L / 2 minutes, that is 2566 L / hr. Where is 1363 coming from?

[Nicola]

I found the data sheet of my Hall effect 3 wires flow sensor: it produces a square wave, with frequency [Hz] = 0.5 x Q [liter/min]. As I know my typical irrigation flow is 100 liters/min (recommended range of my 1.5″ flow sensor is 10-150 l/min), the maximum frequency is 50 Hz = 50 pulses per second. Is this too much to handle for the OS ? Also I am irrigating in 15 minutes cycles, so total flow count is something like 50x60x15 = 45000, too high ? Thanks for checking into this.
Again I would gladly go with the 2-wires flow meters, but at 1″ thick they are 10″ long, I have no room in the pipes to install them.

[Nicola]

Not the UI, I am getting negative numbers in the email body sent via IFTT, for instance:

Station Z4 Acqued Lato W closed. It ran for 5 minutes 0 seconds. Flow rate: 1818.-90

Do you have a public IP ? What are the first two digits if you go to a site like https://v4.ident.me/ ?

If you have a static public IP, you forward a port in our router to the fixed local IP of your OS, say port 121 for instance, then you can connect to it from outside the lan or from the android app using your_ip:121

If you have a dynamic public IP, you need to setup an account with noip, dyndns etc with your own alias, say myLANip.dynddns.org, and setup your router to refresh it when it changes, then you can connect to it using myLANip.dynddns.org:121.

If you don’t have a public IP, such as your double natted behind an LTE connection, you are out of luck I am afraid, you can only setup a small pc or raspberry always on in your lan with anydesk, teamviewer, remote.it etc, and use it to log into your OS.
See my other post on this very topic.

[Nicola]

There is no access to both gateways, the almost totality of LTE providers don’t give you a public IP, they do the first level of nat. Starlink does also the same, in all these cases the IP that you see in sites like whatismyip.com is not a public IP and you cannot update a dyndns service with it.
My old slow DSL that I used for years has been discontinued by the provider because of bad old phone lines that they deemed too expansive to replace. They proposed a FWA that is also natted as Starlink and LTE modems.
I am sure I am not the only one with this problem, do you have any plan to provide some cloud access, even if for a fee? It’s a huge limitation otherwise, only option is to remotely access a LAN PC/raspberry via VNC/TeamViewer/Anydesk/etc and log from there.

[Nicola]

To add to it, sure I have a small PC with Teamviewer running in the LAN and I can use it to log into the OS webpage, but it’s not nearly as practical as using the OS Android App…

I saw in the donwload section what looks like a firmware 2.1.9 v3:

os_219_3.hex 2020-04-06 00:00 218K

Is that it? what are the difference with v2/v1 ?

[Nicola]

I had a very similar experience (OS 2.3, fw 2.1.9). As the unit is located in Italy, I changed the time server to ntp1.inrim.it (193.204.114.232) and it works well now.

[Nicola]

Same issue here: OS 2.3 AC, it came with SD card. first attempt to turn it on, 0x2D. Put SD card in Windows 10 PC, Computer Management does not see it among the drives so I cannot format it. With no card, OS also boots in 0x2D. I don’t have a spare small SD card, what can I do? I think it came with 2.17 fw

[Nicola]

I second this user request, I use two OS and need to get personalized messages from them.
Thanks for the workaround.

[Nicola]

Upon further testing:
If time is entered by clicking on the arrow buttons, it maxes out at 18h, and saved correctly.
If it’s entered via keyboard, like 24h l, it shows 1d also after saving, but then preview programs show 5h47m47s. Same thing when entering 23h59m59s

Looks like a bug…?
