Not op but I grow pollinator gardens in my community garden which typically attracts bees, hummingbirds etc.; check with your local nursery because there should be a native plant seed mix you can buy.

You may be a little late in the season (assuming northern hemisphere) for most seed mixes because I’ve mostly seen suggested sowing in fall or late spring

I have been living in Vancouver’s downtown east side (de facto epicentre of drug use) for nearly a decade and this is the first I’ve heard of the programme. If it’s been on for a while there’s been no change. If it get reversed there will still be no change

Otherwise I’d have to install a gui

If you’re already using an esp32 why not just get a simple ultrasonic sensor and measure flow on an indoor inlet pipe? You may need to know the pressure (probably 1.7 kPa) and temperature but that should be possible to calibrate against your meter readings

Then your project just becomes a simple pipe clamp that can be indoors
