It may seem like a complicated stack compared to monitoring with rrdtool, but the wireless environmental monitoring with zigbee plans are starting to work. The zigbee stick arrived, I found out I needed to upgrade the Raspberry Pi in the utility closet to be able to run zigbee2mqtt so I did that: Raspberry pi monitoring the smart meter is now installed and the zigbee environment sensors arrived and the first one joined the network. After some changes to mqtt-to-influxdb-forwarder I was able to get the data into influxdb. The final step was to tell grafana where to find the data and create a dashboard visualizing the results, see the screenshot. I'm also improving small things in using zigbee sensors and improving data collection. After learning about not leaving the network running with permit_join true I had a look at the configuration messages I can send to zigbee2mqtt. It is clear zigbee2mqtt is not just from zigbee sensors to mqtt messages but also the other way around, both to adjust settings in zigbee2mqtt itself and to send commands to zigbee devices. I did change the friendly_name of the first sensor to the name of the room it is in, and it's now showing up in the statistics under that name. This does break the history, so I should change the name as soon as I add a sensor to the zigbee network.
