Last week, while my back was destroyed, I got fed up with running my #homegrow lights by hand. (#Snarkhome is still having #zigbee issues and I regret ever buying a zigbee radio. #Zwave has been so much more reliable, especially over a scale of decades.)

I repurposed an old (and terribly fucking unsafe! do not recommend!!)
#switchbot plug under #esphome to run autonomously on a schedule. All it depends on is wifi + internet, and if my internet starts going down I'll just go back to plan A and build one from scratch with an RTC. I doubt a #marijuana plant keeps better time than a cheap crystal oscillator. (As a bonus, it participates in #bigear so I can remove one of the annoying rover boards. Who builds an embedded board that doesn't boot without manual button pushes!?! Ahem.)

On the first run,
#HomeAssistant sends down the sunrise and sunset times but after that it relies on stored values and SNTP. I still need to test that, but first I want to watch it go on and off for a couple of days. (And maybe make a second one so I don't have to blink the grow tent every time I want to screw with it.)

I also reworked my traffic light sensor from scratch. Now it also checks the
#ble illuminance sensor, not just power drain and relay state, and it doesn't go unknown periodically when HA can't get the attributes updated correctly. (Bad news there is that I did not calibrate the power sensor yet, and it seems to be reading just high enough to be irritating.)

Closing rant: Why can't I CW the post but not the media? This screenshot is significantly less spicy than the text. Not even a mention of
#weed. BUT! Since I have to CW the pictures anyway, you get a bonus pic of Madam Prez (Prez Candy, listed as President Kush x ARC x 91 Chemdog.)
She's in flower week 7 and might be coming down as soon as next week. This grow is an experiment in pure low stress training. No pruning, barely any leaves off even, just wired her down horizontally, then repeated on her larger branches once they popped. It seems to have worked. I wasn't expecting much, but they are forming up some lovely secondary colas. With a little actual training it could be insane.

I swear that #BigEar had nothing to do with the #toothbrush story.

Don't look at me like that. I'm disappointed in me too.

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.

Wait how come the new hydrometer is showing on that dashboard? Did I accidentally rename an old one?

Nope. Turns out I used auto-entities and it was magic enough to pick it right up.
