I’ve got something functional but haven’t managed to keep pace with luma’s changes. Really the only big ones I don’t have working are the alarm panel and automatic backlight brightness by sunrise and sunset. The former I probably won’t get to but the latter is pretty high on my list… if I can ever get my pi to cooperate. I’ve got an Intel NUC on the way later this week since I’m tired of my pi locking up every single day or multiple times per day. HassOS has been so much worse than ResinOS ever was.
That aside, later today when I can get physical access to it so I can reboot it I’ll pull the flow out of it and post it here.
Upgraded the MQTT Add-On to 4.1 last night and both HASwitchplates became unable to connect to the broker. Restored 4.0 and all is OK. Same problem whether 88.2 or 89.1.
Have not researched yet.
@luma Trying your PCB order like http://www.allpcb.com/setinvite.aspx?inviteid=34099&url=https://www.allpcb.com/
It does not seem to work.
I did buy a board from you. To be honest, I just trying to personally experience the PCB “short-run”. Because yours has been printed once, I thought I would use it for my learning experience.
Do you have a new one or an updated link. I would love for you to get some credit on all the hard work you have done.
Unfortunately their referral system is broken at the moment. Nothing much for it but to wait until they fix it on their side. Thanks for trying though!
BTW here’s the current nodeRED flow. It still needs cleaning/has comments/etc. But should put you a pretty long way to getting started. As before, I avoided functions as best as I could.
Actually, looks like to whole system is down.
After some searching around, I found some places that give “instance quote”.
They need dimensions, thickness, layers for a quote, I have not received the board I order from your Tindie store. I just order it today.
Do you know those values off the top of your head?
If allpcb is down, who would you use next?
I sure after uploading files, they give you an exact amount. Just curious, how did you vet them?
I found this URL https://pcbshopper.com/ I was using 75 x 26 mm. Silk screening did not seem to make a difference in price.
60m x 40mm, all other options can be default with every PCB shop I’ve ever used (1.6mm FR4 board, dual sided, 1oz copper). PCBShopper is a great solution!
Looking at the parts list and this image PCB Picture, what is the transistor for? Switching the display?
Also, the header to the right of the antenna? Part of the radar?
Do you have anywhere you are discussing the radar? I have one that I was going to mess with from another project and would like to play with it.
Correct on both accounts. On occasion the Nextion firmware update process fails, and when doing so, leaves the display in a hung state that requires a power cycle. This is problematic when mounted inside the wall, so I added the transistor/resistor to act as a simple low-side switch to power cycle the Nextion on every boot, allowing the user to run the update process again.
The header is there for whatever expansion idea we come up with next. I discussed using an RCWL-0516 connected to that header but found it was experiencing way too many false positives to be useful. Not certain if it was the LCD screen mounted directly in front of it, or just crappy sensors, but it for sure wasn’t usable so I scrapped that plan. That header has power, GPIO, the one analog IO port, and serial debug broken out to it for whatever purpose you might think of.
Excellent project, i’ve had one screen up and running on one setup for a while now without pcbs. Have just got my pcbs from ALLPCB and everything set up in a new HA installation with default values and have triggered the first time automation - (plate01 accesible at web address and shows mqtt connnected etc…) but Nextion display just stuck on HASP initializing, any ideas?
If it’s not page 0 then also check your connection. I thought I checked and double checked by my connections were switched for rx and tx. Switched them and it was good to go.
thanks but no further along, blue to D7 and yellow to D4 as per assembly documentation, tried switching and rewiring but no change. Checked active screen as per myle’s suggestion as well still stuck on page 0.
don’t know if this helps debugging but have this output from plate webpage:
If all you are seeing is “HASP Initializing” with no QR code that suggests the WeMos is not sending data to the Nextion. Can you maybe post pics of your setup?
Thanks - Replaced the wemos and that problem now resolved. Short lived success though as now the touchscreen is unresponsive - can change pages, colour etc through the home assistant interface but no response to touch on Nextion
So similar process there, you need to make sure that data both to and from the panel is working correctly. If you can make HASP switch pages and the like, that means TX from HASP is getting to RX on the panel. If button presses aren’t being picked up, check to make sure TX from the panel is making it to RX on the HASP. If you have a serial connection open you should be able to see user interactions sent by the panel displayed in the serial log.
