An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine or advice forum.
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions, identify objects or get advice. We accept very few questions, and they must be over topics much more difficult than what is easily discoverable with a search. Also see rule 1, “comment baiting”.
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. Not hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.
8. All polls must have an "Africa, by Toto" option. Why? Because we hear the drums echoing tonight.

Same.
My next thing is to try to automate a clunky old window A/C unit via infrared. I might do it with an Aqara M3 hub but I’ve got some Raspberry Pi Zero W laying around too.
Any suggestions for copying a garage remote? I’d like to automate a garage but don’t want to mess with the wiring (this is a rental after all). I know the remote can be copied because my wife’s Jeep cloned it already.
One of the first projects I did was an IR setup for my AC window unit! At the time there weren't an overwhelming number of options, but I settled on a Broadlink IR remote like this one: https://www.amazon.com/Broadlink-RM4-Universal-Control-Compatible/dp/B07ZSF46BX
I don't have it running anymore, but I remember I was able to train it on codes through HA. The training process is subject to a little randomness in the IR signal from your remote. To get the codes right I wound up sending the training signal several times (I'm a nerd so I definitely did at least 10), then copying them into excel to find the statistical most common hex pairs to make up the code I saved in HA, e g.,
FC:G3:D4CC:G3:B4CC:G5:D4Becomes
CC:G3:D4, and that dramatically improved the success rate of using the trained command to control things.For the garage opener, honestly the wiring on those are pretty simple, easiest option is definitely to get a specialty made controller like https://www.amazon.com/Smart-Garage-Opener-Chamberlain-myQ-G0401/dp/B08GD3D9YJ, but a simple Shelly relay can do the job in most cases.
If you're really wiring averse, you could try something like this: https://www.amazon.com/Automation-Ceiling-Fireplace-through-Control/dp/B071GVGVVH
It says its not for garage doors so be prepared to have to return it.
If youre feeling really clever, you could also consider something like a Switchbot with a dumb remote, and just keep the remote in your garage. https://www.amazon.com/SwitchBot-Smart-Switch-Button-Pusher/dp/B07B4D9KVX
