I have a few Ruuvitags around the house. They work fine with the official iOS app and I see all data without issues, although the range is pretty bad. So the tags are fine. I want to collect some data (like everyone else) automatically and be able to draw some nice charts and correlate stuff with our solar panel data.
So, I have an Intel NUC and installed a fresh Ubuntu 22.04 (23.04 required too much memory and the installer died). I’m using the Python library at https://github.com/ttu/ruuvitag-sensor. When trying to find the sensors none are ever found.
% pip install ruuvitag-sensor
...
% python

>>> import ruuvitag_sensor.log
>>> from ruuvitag_sensor.ruuvi import RuuviTagSensor
>>> ruuvitag_sensor.log.enable_console()
>>> RuuviTagSensor.find_ruuvitags()

I left it running for a while and nothing was ever found. Some setup data:
% hciconfig

Doing a manual scan does find a lot of stuff and also the sensors:
% sudo hcitool lescan

If I use the nicer library simple-ruuvitag from https://github.com/ruuvi-friends/simple-ruuvitag:
% pip install simple_ruuvitag

With this library I can create a small app that’s pretty similar to the official one:
import datetime
from time import sleep
from simple_ruuvitag import RuuviTagClient
macs = ["dc:2c:0d:0d:db:9a",
"fd:07:ae:49:b0:bc",
"FF:28:1A:19:B1:98"]
def handle_callback(mac_address, data):
mac = data["mac"]
temperature = data["temperature"]
humidity = data["humidity"]
pressure = data["pressure"]
print(f"{datetime.datetime.now()} {mac}: temperature: {temperature}, hum: {humidity}, pressure: {pressure}")
def main():
ruuvi_client = RuuviTagClient(callback=handle_callback, mac_addresses=macs)
ruuvi_client.start()
while True:
ruuvi_client.rescan()
sleep(5)
if __name__ == '__main__':
main()
This app gives me:
% (venv) sudo ./ruuvi-server.py

It seems to catch all the announcements and the data looks sane (assuming you think 9.43C in June is sane). So clearly the machine is able to get all data, but why would the official API not be able to do anything useful? The simple-ruuvitag library works fine, but it hasn’t been updated in three years and it’ll likely break sooner or later and I would rather be riding the official train.
Any ideas?
