Hi, I have a dashboard with 20 gauges on it, once a month I have to open a new window and type "scrot -d 20" , I then minimise the window and the screenshot is taken, I then manually send the image via e-mail to a friend, my question is could this process be automated so that it could be done if i …

Hi, honestly it depends on how much time / effort you want to spend on it plus the environment you're running on. Looks like Linux? If it is simply once a month is it worth automating? I think you could cobble something together with a shell script for this... Read and format the current date. …

Hi, It is on a raspberry pi running node red , I have found a suitable sheduler called cronplus which can stipulate the time of month trigger, there are a few screenshot nodes, but i just don't really know where to start putting them togethor to send via email, any help grately appreciated cheers …

The problem is, node-red (including cron-plus) work at the server side. The browser is 100% client side. You could, as suggested, trigger a shell script IF node-red is on same machine as browser.... Cron-plus > exec shell > (opens browser) Uicontrol (detect connection to dashboard) > exec shell (…

If Microsoft's new browser testing/automation library Playwright installs on a Raspberry, it might be quite a straightforward route for getting the screenshot. You would create a standalone Node.js script to do that, then use exec node to run it. Here's an example code snippet from their documentat…

Hi, Everything is on the pi, the screenshot that i want to take is of the node-red dashboard which constantly displays my 20 gauges,on the pi, so everything is server side. Thanks Stuart

Why? Why image? 20 gauges is 20 values. Gauge shows current state of some measurement. Why the friend needs picture of gauges. You can easily format the email content as current state of your measurements as json which in other end can be feed to local node red and show the state with gauges. But wh…

Hi hotNipi, i am just looking for an easy option, the gauges are 20 temperatures that are updated every 3 mins via mtqq sensors on the network, i need to email the temperatures once a month to a collegue, all very easy when i am there but the childrens charity that i work for are having to fulough …

It really depends on how your flows are created but simple strategy will be to hold one global object of all measurements which have named parameters of different measured targets. Then with every incoming measurement update also the global object and if time comes for report just read values from t…

Hi hotNipi, yes it is more complicated than it seems, i seem to remember asking about this some time ago and nobody could help, in my mind what i would do is just put the values into variables as they come in, then an email could be made from adding the variables, but i beleive there is something o…
