Working on my #liquidClock

It's awesome how little code it needs to work.

The strategy for datetime updates is to get a hourly timestamp to synchronize via mqtt.

Of couse we have #neopixel lighting in the living room. #dollhouse #iot #yot

This is the #iot #yot dollhouse.

What this story solved:

I once improved a dollhouse with an old house gong ding-dong bell. Then I added an #Arduino to trigger it with my not-so-smart doorbell of my real home. It was awesome. But some weeks ago it stopped working, so the solution was, to fix something in a remote datacenter in another country on a virtual server. To make a ding go dong.

That does not seem right.

Thanks for reading :)

Last thing to say is: In the recent years I began to call #IoT the term #YoT , because you should really ask the question if it is worth to connect all the things

I only depend on mosquitto_sub and pub for live demos and debugging, so the charmful workaround was to register another listener for the default port like
`listener 1883`
`protocol mqtt`

Now I am happy again, my bridge works and all my privacy is gone again.

Updating to the #snap release of mosquitto was the most simple way to fix the first problem (reconnects).

The second problem should be no problem, but the shell clients seem not to allow unencrypted 8883 connections. There are some command line options that should circumvent the problem `--insecure`.
But *protocol error* still occurred.
Related problem 5 years ago :/ https://stackoverflow.com/questions/56361192/configuring-mosquitto-mqtt-broker-to-listen-on-multiple-ports

Another #IoT journey report.

My broker was no more compatible to the bridge at home so continuous reconnects every second was the result.

Another problem is that I serve non-encrypted mqtt over 8883 what confuses the #mosquitto clients.

(8883 is the default for TLS encrypted connections)

Changing that port is not an option as enough devices in the #hackerspace and at friends homes depend on it.
