2021-06-12 First light on zigbee environment sensors 4 days ago
The package with the zigbee environment sensors I ordered arrived this morning and I had to get the first test done right away.

Joining the network/resetting the sensor is easy with a long press of the button and it showed up:

2021-06-11 I will need a fresh raspberrypi install for zigbee2mqtt 4 days ago
I started looking at the instructions for running zigbee2mqtt and the instructions for installing npm/nodejs gave me a lot of error messages on the raspberrypi running in the utility closet and checking the smart meter.

It turns out it needs an upgrade from Raspbian jessie. This Raspberry Pi is dedicated to reading the smart meter since August 2016 and it has been running fine gathering the smart meter data.

The raspbian forums state that it is better to upgrade by reinstallation on a different SD card. So I guess it's time to rebuild the smartmeter Pi if I want it to run the zigbee sensor network.

Update:
I installed all the software on a linux laptop and now I have a running zigbee2mqtt.

2021-06-09 The Electrolama zigbee stick comes in from England: time to pay taxes! 1 week ago
The zigbee stick I ordered for environmental monitoring at home is making its way over here and I received an sms about the duty and tax to be paid for importing it from the United Kingdom. Indeed, since brexit taxes have to be paid.

My first reaction when receiving an sms about a package was to think of malware attempts since that has been in the news recently. So I checked carefully. It's good dpd also sends an e-mail with the same information, and I can check the validity of the links and the source of the e-mail a lot better on a computer.

2021-06-07 Wireless enviromental monitoring with zigbee 1 week ago
Since January 2008 I measure temperatures and other environmental data in and around the house with 1-wire sensors and adaptors. These work fine but need wires between the sensors and that isn't ideal for quick spot measurements.

So I looked into other options recently, and found affordable zigbee temperature/air pressure/humidity sensors. And an USB zigbee interface which works with linux and with a lot of the available application software. Because the next problem is going sensor - zigbee network - zigbee usb interface - some magic - database of measurements.

Because I see myself wanting long series of measurements from a number of places in the house and testing without breaking those series I ordered two USB zigbee interfaces and eight environmental sensors. I guess I want production and development enviromental monitoring.

The zigbee stick is not the cheapest solution but it is documented to work with zigbee2mqtt and buying one supports work on that software.
