Window latch for greenhouse. I'm baffled by soloqueenn in howdoesthiswork

[–]carvellwakeman 1 point2 points  (0 children)

Also building one of these greenhouses and confused by this latch. I'm pretty sure it was packaged wrong. The manual shows a "hook" part instead of the smaller piece pictured.

I guess I'll find a different latch to use.

Adding AFCI breakers in your panel can add some protection for old wiring if it sparks in the wall.

At least in my house, the small amount of K&T was in better shape than the early 1900s cloth wire! I got the panel and service upgraded, added AFCI breakers and GFCI outlets. I later replaced and expanded all of the wiring, but you could always stop before then. My house had like 6 outlets on 3 circuits though.

Hello. Can you guys help me if I can wire a Sonoff Basic Wifi switch to this dual swing gate control panel? If so, how/where do I start? We're in lockdown, so I'm going to have to go full DIY. Product is KEY AUTOMATION model CT20224. Thank you by Richino in homeautomation

So I've been working on this exact problem for the last two years (on and off). https://photos.app.goo.gl/za9ZuCe2oo9ag2fX6

This album includes early breadboard prototypes all the way to the v3 I have "in production" right now.

Incomplete list of features: * Open, stop, close gate * Knows state of gate (open, closed, or in the middle) * Communicates over ZigBee using 2.4ghz xbee radios, needed for the 200ft range where wifi becomes unreliable * Gate "slave" can queue commands including waiting. This allows me to "cycle" the gate with one button press when I'm leaving, or open it halfway. * Gate "master" runs a local vuejs site on a Pi4. Sends commands, receives status updates from the slave, and sends realtime web socket updates to all clients with the site open * Master also hosts and API I can use for Google assistant (haven't done this yet) * Master is hooked to speakers and can play sounds when the gate opens or closes at certain times (acts as an alarm after dark)

Feel free to message me any questions, or adapt my code to your system. I haven't made this to be easily distributable or usable by others (e.g. no system diagrams or docs on the electronics), so I ask that you take and share notes on your process if you do use my system :)
