  In the event monitor of FHEM I can see also the following message when I make a "get all": "2022.01.02 14:17:08 3: Neuron (NeuronL513) error decoding response: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 5830 (before "NaN, "circuit": "3_0...") at ./FHEM/00_Neuron.pm line 424." As I can see the error occurs on AI 3_01 or an other till AI 3_04.

  It is a problem related to power-supply. It was some voltage peaks while connecting anything to the same circuit as power-supply. I've a better one (Phoenix Contact) and it's working stable now. Topic closed.

  The issue was caused by a combination of 64bit Linux kernel and bundled pigpio subsystem (used for peripheral access). After pigpio updating, Evok works on a 64bit platform properly. This change will be part of the next release.

  Sysfs interface support for extension modules (Pt.2)

  Hi @tja, this is not planned, nor it makes sense from the architecture point of view. The SysFS endpoints are generated from the Unipi kernel module, which is aware of the HW it is running on, but not aware of any peripheral devices. The only way right now is the Evok, or you can directly poll the devices over ModbusRTU. We have some internal discussion from time to time about adding support for extensions to our ModbusTCP service. So far, no work has been done on that part. Best regards, Martin

  Hello @sknobloch, if your program is some script or binary, you should use systemd for starting and keeping alive. This tutorial shows how to work with it: https://medium.com/@benmorel/creating-a-linux-service-with-systemd-611b5c8b91d6 Best regards, Martin

  Hello @smontosa, please try to download the current version 2.4.10. The issue should be fixed. Please note that watchdog settings (same as other parameters) are stored in RAM memory by default. To burn it into non-volatile memory (FLASH), use the appropriate coil 1003 or call the separate REST request on the same endpoint with parameter nv_save=1.

  Hello @mglowinski, sorry, but this feature is not supported in Unipi 1.1 series products. Please consider buying Neuron/Patron series PLCs which can do it.

  Hello, unfortunately, the Unipi 1.1 does not have a watchdog device. You can see all available devices/circuits in reply to the "all" GET request. Example (can be invoked from your web browser): http://<your_unit_IP>:8080/json/all

  Hello @mglowinski, the Evok doesn't have such logic. If the DI doesn't support counters (which does not on Unipi 1.1), the Evok is not able to share this information. This has to be done in your software. Best regards, Martin

  To make extension relay module (EMO-R8) working with EVOK below steps needs to be done: Open /etc/evok.conf file Uncomment relays assigned to EMO-R8: Each this line begins with a character ; This character must be removed for all lines related to the configuration for EMO-R8: ; ;Example of 8xRelay extension module addon (EMO-R8) on address 0x21 ; [MCP_2] i2cbus = 1 address = 0x21 [RELAY_9] mcp = 2 pin = 7 [RELAY_10] mcp = 2 pin = 6 [RELAY_11] mcp = 2 pin = 5 [RELAY_12] mcp = 2 pin = 4 [RELAY_13] mcp = 2 pin = 3 [RELAY_14] mcp = 2 pin = 2 [RELAY_15] mcp = 2 pin = 1 [RELAY_16] mcp = 2 pin = 0 Save /etc/evok.conf file Restart evok

  Hello @Achilleas-Kotsis, the issue is not with the unipi-kernel-module, but with the unipi-firmware 5.52. We have removed it from our repository and advise to downgrade to 5.50 (and flash it to the HW via /opt/unipi/tools/fwspi). We are working on the fix. Thank you again for reporting this issue and have a nice day, Martin
