First a quick rant: DO NOT BUY SWITCHBOT. They are unsafe and have no warranty and they can suck whatever piece of my anatomy they find most distasteful. We couldn't afford to replace them, but we had to anyway because Fire is Bad.

Ahem. Anyway. Yes! The grow is driven by
#HomeAssistant (along with the rest of the #snarkhouse.) I can post the grow hardware BoM (my lights, plugs, etc) if you're interested, but the basic stack is #HomeAssistant as a #Truenas VM with everything else on ARM64 under #k3s. The control plane is CM4 on #TuringPi2, and Zigbee/Zwave pods talk to ser2sock + node-feature-detector to find their USB radios. (They are plugged into the client port of the Turing, so I can move them programmatically.)

On the far side of the radios, a cheap
#esp32 Rover handles #bigear listening as well as the MiFloras and #BLE hygrometers. Inside the grow tent, an #esp32cam on a 3d printed mount watches over the grow. Power relays are a mix of old #Securifi peanuts and new #ThirdReality switches. (DO NOT BUY SWITCHBOT.)

Edit to add: I use power use to confirm that the lights and such are working, and templated 'traffic light' sensors (ok/error) confirm that the schedule, the switch and the power drain all align. If it goes red, the house starts shouting at us about it.

Wanna know what LEO is doing nearby? Me too.

uses heavily. I think I am going to build some more interesting listeners this winter. (I'm disenchanted with pure + as a framework. Maybe raw mqtt..)

I am also having more and more trouble saying "I don't need a ham license" with a straight face.

Sunday the soil root stuff arrives and they go into little pots. The yellow 3 get ready for outside while the others stay here (gender permitting)

The absolute best part of the #BigEar project is that I can just buy random #BLE sensors and throw them anywhere. Security is such a joke (its just broadcast) but the threat model is "someone driving past might notice that my pool is warm." 🤷 🌡️

(I do mean REALLY anywhere though, within about 4 yards/houses in most directions, using zero equipment outside the main house. Later I'll waterproof one and try it on the fence..)

Y'all shouldn't be buying
#oralb toothbrushes or really ANY #bluetooth bathroom scale. Just saying. (And yes, I can probably see your growroom sensor too.)

This is the one on my desk. No ads on mine 😸

Just a busted printer while I wait for them to actually ship my parts. (The extra week pre-ship delay has me irritable.)

On the right, the thinks the cat is nearby, the weather is HOT but wind/rain are low (good for flying ) and both the air and the pool are nasty levels of hot. (Air via , pool via a floating sensor.)

@mharleydev
Definitely. If it were me, I would just mad-scientist the extra fob to an or and stick electrodes in it's brain. (It probably runs off 3V, so you could power it from the ESP and save batteries.) That also prevents physical alignment shifts; it won't ever accidentally push panic instead, unless you soldered it wrong.

This approach is basically what I imposed on our coffee maker. It has a wifi plug as a current sensor purely to detect manual runs, and a little esp32+relay inside that bridges the button contacts for automatic runs. The whole thing hides under the pot (no warmer in this one) and is only visible because of the extra usb wire. (Since the upgrade, it also participates as a listening-post.)

As it has evolved over the years, I've been too lazy to look for DC inside. If I ever do V2 I will fix that, and get rid of the relay and wall-wart in favor of instrumenting the switch+led directly.

I had to adjust the thresholds, so I have held off on installing the remaining sensors. It's working under a foam mattress though, very impressive. If paper ends up not working, I've saved up Amazon bubble envelope mailers to try instead.
And the node doesn't seem to care about the added load, as hoped.

Continued thread

Success! It is running on the node, stuffed into a quick from github.com/mrWheel/YAPP_Box . Today I'll wire the partner's side and add some automation. (If you are playing along at home, you want to mess with the attenuation settings in esp_touch to expand the sensor range. It starts around "6-7" but you can get up to "10-30". Much more reliable.)

The wild sleeps on a specific pillow in a specific spot, and there is wiring access, so I might give him his own personal sensor for funsies. The foot-of-bed sensors are less useful anyway.
