It would be great if more smart devices had a LAN-only control mode like my 3D printer, TV and AV receiver.
I would be perfectly happy if my iRobot phone app only worked from inside my network.
Doesn't apply to iRobot but there are lots of robot vacuums that can be flashed with an open firmware with just a USB UART cable: https://valetudo.cloud/pages/general/supported-robots.html
As for the other devices, my 3D printer, projector and AV receiver are all locally controlled.
Big +1 for Valetudo. I use it on a refurbished Roborock S7+ I got on eBay and it's fantastic.
How was your experience rooting it?
I've been really wanting a Roborock for a while but I saw that changes starting on I think their S6 model made rooting it much more difficult and required a pretty extensive disassembly process.
I'm pretty comfortable with electronics teardowns but the thought of having to fully disassemble my brand new device to root it made me decide to wait a little and see how things shake out. I haven't looked into it seriously for maybe a year or so though so I don't know what has changed.
Same experience as domi, had to take the whole thing apart. It was pretty straightforward as the guide was excellent. My only regret is forgetting to enable SSH access before reassembling it.
I rooted both of my Roborock S6.
If you can solder and have an UART USB cable, it's not really hard to do. Technically you can flash it by just holding your UART adapter against the solder pads but soldering them on definitely makes it easier.
There's a full video guide on how to dissassemble and root here: https://www.youtube.com/playlist?list=PL9PoaNtZCJRZc61c792VCr_I6jQK_IdSb
Firmware and everything else is here: https://builder.dontvacuum.me/_s6.html
Also, if you don't have a Roborock yet, the Dreame models are significantly easier to root. Don't even have to disassemble most of them.
Thank you. Funny enough it looks like I've already watched both of those videos last time I was looking into this. I'm comfortable soldering but it was yet another barrier to me actually making a purchase.
I'll check out Dreame, I have not heard much about them.
I've had two Neato's in the past and I really miss having one but I now live in a split-level house and the convenience factor drops down a lot when you have to carry it between floors all the time rather than just coming home to a freshly cleaned carpet.
Roborock, Dreame and Xiaomi are functionally almost identical. Some of them even share the same parts.
If you want to root them, get a Dreame or a Xiaomi. Most of them are rootable without disassembly, see the list linked above.
Make sure to read their disclaimers, they're really not interested in expanding features, so make double sure it's sufficient for what you want.
At that point, I wouldn't trust ANY device that cannot be controlled locally, either natively or at least through some hacks.
I think it's just using MQTT, so block network access and use HomeAssistant
Your 3d printer has a NIC?
It's pretty common for newer 3D printers to have WiFi. Start/stop jobs, monitor cameras, or just to have a more capable UI than the built-in screen. Lots of people add this capability to older printers (or new ones with sucky interfaces) with OctoPrint.
I have an ender 3 and Im glad it doesn't do any of that. So much more complicated
And some brands of 3D printers have started placing those functionalities behind remote servers and paywalls
cough cough Bambu Labs cough cough
BambuLab A1 Mini. It has a WNIC.
Hmm. Interesting.
My cheap Conga robot came with a remote controller. It stopped connecting to its server long ago, but I can still use it. The battery is getting worse and worse, though.
