@Matt Did you manage to write a better PID implementation in Mervis that you could share? When using the built-in PID logic for controlling hydronic underfloor heating valves (huge time delay), it only acts as a pure PI controller.

The problem has been solved by flashing the latest firmware.

Here is a picture

Hi All, I just got a PRO380 to measure energy from my solar panels from my Neuron device. Since I don't want to run (learn ;-)) NodeRed and there is no turn key solution for native integration of the MOD380 in Evok I searched the internet and found this; https://github.com/volkszaehler/mbmd This spins up a webserver with API and MQTT / InfluxDB integration for different energy meter including the PRO380. Works like a charm for me. Some steps I did; Connect the meter to a RS485 port on the Unipi and enable the dip-switch Make sure that for that particular RS485 port there is no config in /etc/evok.conf (So yes, you need a unused / free port). When I had the port configured in the conf file I did not work, presumably because Evok is intercepting the traffic) Download the pre-compiled binaries from GitHub and extract as documented Perform a scan over modbus to see if your device is found with the command /usr/local/bin/mbmd scan --rtu -v --raw --comset 8E1 -a /dev/ttyNS1 . Note that ttyNS1 is my SECOND port on my device (2.01). Adjust this as needed for your device. My Output was the following (I changed the ID of the PRO380 to 5 on the device: 2020/11/25 09:47:52 config: creating RTU connection for /dev/ttyNS1 (9600baud, 8E1) 2020/11/25 09:47:52 starting bus scan on /dev/ttyNS1 2020/11/25 09:47:56 device 1: n/a 2020/11/25 09:48:00 device 2: n/a 2020/11/25 09:48:04 device 3: n/a 2020/11/25 09:48:08 device 4: n/a 2020/11/25 09:48:10 device 5: INEPRO type device found, VoltageL1: 239.90 Start the webserver with the command /usr/local/bin/mbmd run --rtu --comset 8E1 -a /dev/ttyNS1 -d INEPRO:5 --mqtt-broker tcp://1.1.1.1:1883 --api 0.0.0.0:1380. Also make sure you adjust the ttyNS port numer. As example I included a MQTT broker IP. Please read the docs for further config or InfluxDB integration. Do Note that I redirect the webserver port to 1380 because 8080 is already in use. Go to the IP of your Neuron device on port 1380 and see what happens. I see the information coming up nicely. :-). There are API possibilities too to extract data, or push via MQTT or InfluxDB. If this is what you want to keep, set up a service to start with your device, how to is also in the docs. Perhaps this helps someone. It fairly easy to use. :-)

Hi Tomas. Yes, after reinstalling OS on industrial SD card everything its ok. I think the problems became becouse of the wrong settings in Mervis DB and Proxy, also probobly i was saving the project in proxy profile, im not sure. After reinstalling OS i didnt use Proxy or DB and it was ok, few days before i try to connect the controller to db and proxy and problem apear again, lucky i was able to disable them and after cold reboot everything its working fine. I think my settings its wrong, what its correct URL for DB and Proxy server, on Mervis KB site they are the same for diffrent version of Mervis. I got mervis 2.3.0 installed. Also i have some questions: How to in HMI editor create momentary pushbutton? Can i set the delay timer time from HMI and how, i try various options but didnt work. How to create and use fupla blocks, i manage to create one (i think) , it is in solution properties but cant use it, i try to drag and drop but not working. How to do this? Can modbus client and modbus server can be use at the same time? Also i have finger print sensor https://www.ebay.co.uk/itm/USB-Fingerprint-Reader-Scanner-Biometric-Door-Access-Control-Attendance-System/283645765047?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 Any chance to connect it to the controller using UART or USB? Regards.

FYI, it looks like OS 2.2 just doesn't have mDNS/avahi enabled. I've tried it on the M525 and an M505. I was on a different network so I was trying to find the IP address with avahi, and then resorted straight to flashing it when I couldn't find it. It looks like IDE 2.1.3 doesn't support the M525. I've got a solution with two existing M505s I wanted to add it to but it doesn't even show up as an option in the manual device list. Do I have to upgrade my solution to IDE 2.2.0 to add the M525? It looks like this will require me to upgrade the OS on the M505s (from 1.9), correct?

So. Now I solved the problem: After a sudo apt-get remove --purge evok && sudo apt-get update && sudo apt-get upgrade && sudo apt-get install evok and with this new configuration in the evok.conf I got it: [EXTENSION_1] global_id = 2 ; Mandatory, REQUIRED TO BE UNIQUE device_name = xG18 ; Mandatory modbus_uart_port = /dev/extcomm/0/0 ; Mandatory ;neuron_uart_circuit = 1_01 ; Optional allow_register_access = True ; Optional address = 1 ; Optional, scan_frequency = 10 ; Optional, scan_enabled = True ; Optional, ;baud_rate = 19200 ; Optional ;parity = N ; Optional, ;stop_bits = 1 ; Optional

Hi....On the off chance that you need to depend on a steady framework and find support in a crisis case the main route is to ask the network and ideally they will support you, if not. you can help yourself are the issue won't fixed. In my ealry days I attempted to not depend on these open source frameworks because of the missing profound help as referenced in the first post. Be that as it may, OH is so cool and from my perspective truly steady and relyable. Very day a great deal of new stuff is comming and a ton of more gadgets and capacities are actualized. Indeed, we as a whole are simply working here in this network for nothing and attempt to support every others and the is no genuine countable assistance.

Hello @Lebowski, in our PLCs we use the full-version. Best regards, Martin

Hello @Achilleas-Kotsis, I have tried to upgrade the system from a few older images (also with DKMS drivers) and this kind of behaviour did not occur. The issue seems to be coupled with the filesystem write operation and the following sync (should be invoked by umount command in the script). Moreover, the .inc file should be updated formerly within the upgrade process (as the step of unipi-common package postinst script). Can you retry the whole process with a new uSD card? This kind of problems sometimes occurs on corrupted cards as the write operation is not fully synced in fact.

Seems like the problem was a bad Connection or so. Testet something else and had to reconnect the rs485 wires and now it works. Bit weird that mbpoll worked without a problem...

You take any cheap 20$ China Raspberry hat and there is a 2-Page manual (in bad english) that gets you up toggling your inputs and outputs in like 20 minutes. I have now been digging for at least a solid 5 to 8 hours in the unorganized pile of stuff available here. Best I have found out now is Unipi 1.1 is outdated and abondoned. Existing docs do not mention all the things that are unimplemented. I will now just throw away the board and not sink any more time in it.

Hello @Petr-Helebrant, you can use Digital Indicator for that. In the settings, you can assign different images to different states of an integer variable. Best regards, Martin
