Jason,
Agreed. I have pretty good luck with full page (zooming around) with Dash, but I get what you are saying.

Are you doing that using meta tags for the viewport?
Thanks,
Jason

Just straight off of the dash_app. No changes.

The ARM compute instance I setup had 1 CPU and 6GB or RAM and finally broke last night. I’m running PostgreSQL, Redis, Apache Airflow, NodeRED, Jupyter, and a Dash app on it. The final straw was the Airflow job that refreshes the data in the Redis cache every minute. Once running, CPU utilization averaged 100% and navigation of the Dash app was no longer possible. Fortunately, Oracle Cloud Always Free offers up to 4 CPUs and 24GB of RAM for the ARM instances as either four separate compute instances or one single compute instance. My compute instance now has the max CPUs and RAM available and all is running smoothly again! Highly recommend folks grab one of these because they are absolutely free! I haven’t paid Oracle a dime and much cheaper than AWS and others!
Thanks,
Jason

I would like to post my skyweather data directly to excel so I can use Power BI to play around with the data rather than have a paid for app on my phone

I signed up for an account and am working through a basic network set up. Are you doing a push to a remote Mysql? |

I'm putting together a diagram so hang tight. In short, I'm using NodeRED lol. It's like my Swiss Army knife :-)

My home weather station is coming together nicely. Need to optimize the Dash app for the screen and play around with layout some more. The dream is to wall mount the touch screen and have it running all the time in my home somewhere my wife lets me hang it lol  Thanks, Jason |

One of the more challenging aspects of replacing Blynk has been notifications. Within my Blynk app, I've added notifications for various reasons and a Dash application doesn't provide that capability. I think I have a solution. I've created a generic messaging applet in IFTTT that will receive data through a Webhooks and pop up a notification on the IFTTT app on my phone. Not elegant and quite as slick as Blynk but it works lol
Thanks,
Jason

Not perfect but I know when my boat moves to far on anchor or has a high water alarm |

Took a bit of a break from trying to optimize the Dash app for mobile and finally sat down this morning to do a bit of poking around. The page has been formatted for mobile phones in vertical orientation. I'm hoping folks can navigate to the page and share feedback if anything looks really wonky on their phones. Thanks, Jason |

Up at the University of Idaho, they are looking to use something else but Blynk too. They have a big AI / Vineyard / Datawarehousing project that has some SDL legacy software using Blynk but they want to change. I just sent the lead PhD student your link.
Jason, on my iPhone, the graphs are not very useful. I can't get to the zoom out menu.

I actually disabled those menus to get back space :-) Only way to zoom out now is to double tap the menu. The Dash components tend to have a lot of whitespace that I don't like so I've been messing with ways to reduce it.
Please let the student know that I'm having difficulty with the webpage receiving updates over a longer period of time and the site either crashes or simply doesn't update. I've not had time to dig in too deeply to troubleshoot but I'm wondering if it has something to do with gunicorn workers/threads that may be dying over longer periods of time.
Thanks,
Jason
