This project collects data from a digital power meter using a Tasmota based device. The "server" based SW could be installed using a Raspberry Pi with a MQTT broker installed. Details about installation of MQTT broker could be found using aunt Google ;-)

Main part of the SW is subscribed for the MQTT topic from the Tasmota device at the MQTT broker and stored the data in a SQLite3 database. accessing the data is done via a web interface.

All the Raspberry Pi SW could be found in github.

To display the data I created a iOS, iPadOS and macOS application which will be available in Apples App store shortly.

Currently there is one drawback: The raspberry Pi and the SW needs to be available under the server name "hap-nodejs". Otherwise the access from the iOS, iPadOS and macOS app does not work due to self signed https access to the DB web interface.
