This is basically the same question, unless you are interested in historical data. https://astronomy.stackexchange.com/questions/57236/automated-and-hopefully-free-systems-i-can-subscribe-to-sending-email-or-sms-t

@james I am interested in other variable stars as well

I'll second the AAVSO, they have a lot of information for beginners, and advanced equipment isn't necessary.

The [AAVSO](https://www.aavso.org/) (American Association of Variable Star Observers) organises and tracks many variable stars. For example you can see the [latest observations of T CrB](https://app.aavso.org/webobs/results/?star=000-BBW-825&num_results=200) (is this your "blaze star"?). At the time of posting, the most recent observation is within the past few hours and shows it at a nominal 10.3 in the visual "V" band.

They don't do "alerts", but it is simple enough to check their website, type in a star's name (eg "T CrB", or "Algol") and generate a [light curve](https://www.aavso.org/LCGv2/).

You can also subscribe to the [Time sensitive alert](https://www.aavso.org/forum/5012) forum, and get emails about stars that are rapidly changing brightness (as observed by AAVSO members)
