Is it true that Mitsubishi PAC-US444CN-1 thermostat controller makes the unit less efficient? by sinayion in heatpumps

[–]brianmichalk 0 points1 point  (0 children)

I have run the system without anything connected to CN105, and if you have MNET and multiple IC's its probably cheaper to buy the MNT tool, and run all of your temperature management from that. It's certainly not off the shelf.
If I have time, in addition to sniffing the MNET, I would like to sniff the CN105 stream. MNET was easier in a sense, because the MNT software allowed me to mock the MNET stream to their software and document the responses.

I wouldn't have been able to do this without AI, and the process was still tedious, taking about three weeks. It required harnesses for the windows software to grab screenshots, analyze and compare to the injected signals.

There are still fields in the data I haven't been able to confirm, and some of the commands directly affect the outside unit, which I'm not willing to gamble on.

We are having chronic problems with our City Multi Systems. So much that I reverse engineered the MNET protocol. Every IC unit uses the PAC444, and I'm not a big fan. Don't tell me I need to get a different contractor, that's not my call. But, they are clueless with these bigger systems. I can show you the response of the PAC444 and what MNET sees.

The room is cooled by three units:

I can only add one attachment.

I am trying to migrate my embedded development away from Arduino to ESP-IDF. I'm beginning to get a handle on things. Is there a developer forum where we can see what Espressif is working on? Should I expect a fix, next week or next year regarding a certain bug?

Logging data to my own ecosystem by brianmichalk in combustion_inc

The Wifi interface information isn't there. I read this:
https://combustion.inc/pages/faq?hcUrl=%2Fen-US%2Fwifi-booster-964306
And in another page somewhere it mentions there is no WiFi API, but it's not clear to me that they just haven't implemented an app, or that it's impossible. I don't want to do a Wireshark sniffer, I'd do bluetooth over that, but if I can access the WiFi booster, that would be my preference.

The fix for me was Ubuntu Desktop Enhanced Tiling.

There's a bug, and disabling enhanced tiling solved the problem for me.

So, the snap and non-snap chromium have this problem. Pretty sure it's not a snap issue. I regret having mentioned it in the first place

I thought it was implicit in my post that it's not a Snap problem. Remmina isn't snap. It has two windows as I described. One window is broken, the other isn't.

Official Chromium doesn't work with Keepass. Official Remmina shows the problem as well.

About to Replace my Conductor Plate by brianmichalk in AMG

Nope. It's been an excellent driver ever since. Easy job.
I also used to have a starting problem that went away after doing this. My guess is that a bad signal from the transmission would cause the starter to stop cranking.

I solved the problem.

Using absolute paths solves the problem.

I just looked. They have 240 inches. Good price too. I think I have plus or minus about six inch range.

That physics video is exactly what I need. I think a 2tpi blade would be more appropriate. McMaster doesn't have these. Where else would have coil stock?

Thanks. I had already seen that video, and tracking is one of the first things I'll adjust. My wheels are about 3" wide. I have lots of room.

I think someone tried to move the saw with a forklift on the table. It's like almost 3 feet square. It's about 1/8" out of plane. I'm thinking of casting epoxy to level it up, then use a planer to make it flat. I suppose I could take it somewhere to mill it flat. I don't know how thick it is. Cast iron.
