Today, the KNX actuators are being replaced because they smell strange and occasionally emit smoke after the overvoltage damage.

Looks nice with the sunrise!

After removing an actuator, it doesn't look as nice anymore, but in the end, everything shines like new again.

I'm just glad that the KNX power supply has protection, and the KNX button modules are not affected.

Fortunately, only a few actuators were affected, but numerous household appliances, lamps, their power supplies, and heating controls suffered .

Der #Balkonsolar Anlage, die ich von Seiten der IT betreue, ist ein #Shelly #1PM gestorben.

Der hat von gestern 19 Uhr bis heute FrΓΌh 9 Uhr permanent "#Overvoltage" Fehler geschmissen.
Also in einer Zeit, in der die PV keinen Strom geliefert hat.
In der WebUi wurden wohl mal 293Volt angezeigt.

Der #EM3 hat in dem Zeitraum auf keiner der drei Phasen eine Abweichung in der #Spannung gemessen.

Die LED vom 1PM leuchtet jetzt dauerhaft rot.

Hat jemand eine Idee?
