Hello, I have a water meter connected to Homey. Now I would like to calculate the water rate, like litre/min or m^3/h. Is there any example flow for this, please? Regards, Metatron

Pls provide the data it sends now, longpress the watermeter tile and share the screenshot. Example of my power/gasmeter: [Screenshot_20210503-155407_Homey]

Hello, thank you for your answers! First of all, I have only “analogue” water and gas meters, which I have “digitalized” myself with AI-on-the-edge-device . This means, I get meter readings about every 3-4 minutes. This solution works pretty good. In Homey, I created MQTT devices respectively. I a…

This is very hard to do. Every time you get a pulse, the amount of water used changes. But you’ll never know if you’ll get another pulse quickly or not for hours. There’s an app [APP] Insight Trends that might help you to do what you need. It uses the insights to detect for instance rapid changes. …

Hi Edwin, thank you for your reply. Why should I not get a measure for hours? I configure the interval for the AI Raeder, like very 3 minutes, and it is taking pictures within this interval and recognizing the reading. Only if it missreads, then it might skip the results?

It may get new values, but usually Homey does not trigger when a value remains unchanged. It will probably be the same for you. You also mention 3 min per reading. That could be a really short, really big waterflow, or a long and low one. But the more polling you need, the more load on Homey. But I …

Hello, I try to calculate the difference of water, but it is not working. I triggers fine, but does not caculate a difference? Here is the flow: [WhatsApp Image 2021-05-05 at 22.55.24] there is no “and”, [WhatsApp Image 2021-05-05 at 22.55.51] And here the output [WhatsApp Image 2021-05-05 a…

One thing to check if there are no spaces in the equation. Homey seems to have problems with that. Maybe It will mean the equation ends up being a string or something like that. (I didn’t look into what you’re calculating per se, I assume the fact it isn’t a number that is your biggest problem). Did…

Hello Edwin, I generated the equation on IOS and indeed, I found spaces, thanks! Let’s see how it works now. I see you points, but don’t think they are too severe. My meter send data in a fixed interval, let’s say 3min. So whenever I encounter a change, it must have happened within the last 3min.…

For showering, I and many others use a humidity sensor (Aqara or similar) to see a steep humidity rise in order to turn op ventilation and such. Advantage is you can separate it from e.g. the washing machine taking in a lot of water. It is also more to the point in case of ventilation, as it is the …
