  1. The global source for the system is 100W Meanwell 12V AC PSU with battery backup. For the RPI's I use 60W Meanwell 12V to 5V converter that feeds 5.1V into sensor RPI over HAT power port and one other Openhab RPI over USB-C. I now see that HAT power port is indeed has spec from 5.3V volts up. That could be it. I will power it directly from 12V line to be safe. So far it happend only once.
  2. RPI OS with the snapshot brickd pi@morele-sensor-1:~ $ uname -a Linux morele-sensor-1 5.4.72-v7l+ #1356 SMP Thu Oct 22 13:57:51 BST 2020 armv7l GNU/Linux Nothing could be short as it quite fixed on the test stand, and has not been touched except of the removing the power to RPI that fixed problem. Suprisingly all 4 ptc behaved the same.
  3. Ok so I have it working with the new snapshot version but I had today a very strange case where the RPI booted and all 4 x PTC sensors started returning -246.88 readout all 4 the same readout while the remaining 2 bricklets (VC and Humidity2) on the same large HAT were fine. A reboot not helped but removing power from the HAT fixed it.
  4. ok installing, now, I have a 3 way valve governing 2000l of boiling hot water on that one RPi to manage
  5. so you say that RPI OS can fail any time if I put load on the CPU?
  6. Hi is there any known problem with the following setup as in the title? This is the first time I see that, using the TF parts for years now. But I think it is first time I use RPI4. brickd instals fine. But there is constant stream of errors. brickv connects and sometimes after 15 min will maybe see one bricklet but it will timeout a second later. when run in a foreground the log looks the flowing HELP! sherlock@morele-sensor1:~$ sudo brickd --version 2.4.2 sherlock@morele-sensor1:~$ sherlock@morele-sensor1:~$ sherlock@morele-sensor1:~$ sherlock@morele-sensor1:~$ sudo
  7. meh, this is a no go for me, I need a text file config as often I do auto generate things from a template file for repetitive controllers. (like when I have 10 roms with 4 fancoil heaters each). Would that still be a problem when a user would be very careful not to do any things in PaperUI?
  8. Ok, but in the docs somehow I can find of the basic thing definition example by text , hope that is still possible by the text file, and you are not relying on the PaperUI.
  9. Hi, I see that on a German forum there is nice discussion on the Beta OH2 bindings, I wish we have the same here in English./ What is the status of the binding?, is it any good for production use? Can we have some documentation? I'm just starting a new major automation project that will be OH2 based and wonder if I can start using that binding or I have to rely on the custom Python/MQTT bridges for all of inputs and outputs.
  10. I just rebooted the RPI remotely and that fixes the problem, so it looks like the callback function "expired" I have not checked that unit with Brick Viewer but I'm quite sure it was running fine as that motion sensor does have a temp sensor that was reporting the temps fine all that time when the motion sensor was stuck. Next time I catch that I will try to connect with the BrickViewer at that very moment it fails.
  11. forgot to set notifications on that post.
  12. Hi, I have deployed a network of motion sensors on the campus that have fairly simple construction RPI zero -> MasterBrick -> motion 2.0 bricklet. a python script as a service is running on the units with a callback function to send motion as MQTT message. Sometimes (once every 2 weeks) one of 15 units stops motion detection. The script is still running. And restarting it does not fix the problem. Rebooting a whole sensor with RPI is a solution to a problem. But I have no idea how to detect a problem appeared. TIA
  13. C'mon translate that to english, I'm waiting for those proper binding for months.
  14. Hi, I need to read 2 x NTC 10K termistors values, Can that be done with any tinkerforge brick? Maciej
  15. not sure about that one as it has rtc and stuf. but I successfully used this dumber one https://www.aliexpress.com/item/32888533624.html on zero + hat
