Yes, Pushover has not convinced me. I found this on their FAQ:
From here: Messages on our servers are stored in plain-text but are only stored long enough to send them out to your devices, which then check-in with our servers and trigger those messages to be deleted from our database
At least they are being transparent but that does not solve the problem. Security and privacy should be top priority for an ecosystem like OpenHab. Any notification leaving my local instance should be encrypted on my instance and only be decrypted when it reaches my phone. The fact that it stays, even for only a short time, in clear text on their servers is not acceptable.
I thought the local email server would be the only option I had to choose from. I’ll see how easy it is to install a local Postfix instance and may use that.
I’m not a programmer but why would it not be possible to have something like the OpenHab android app running a service in the background that listens for notifications coming in on the same local network?
I understand why some/many people may want a Pushover type solution or may want to connect to the cloud but for those like me that don’t want/need to expose my domotics on the Internet due to privacy/security concerns should also have an option to chose from? I guess the mail binding is one such option. Are there others in the pipeline that people are aware of?
