Hello. I have 2 COLB devices. After upgrading to version 2.7 no more MQTT data is sent. IP, username and password is correct. MQTT Explorer shows no data from COLB! Any of them! Where could be the problem? The situation is critical.

[admin]

take a screen photo of your setting. we can test as your setting. when you short DI with GND , mqtt no feedback?

[hentes]

I've tried every possible setting. In last config I enabled only mqtt but no data is sent. Checked with Mqtt Explorer. 
I had to revert back to previous version but now no modbus data witn node-red and the device freezes after couple of hours. 
In 2-3 hours. 
I will try to download 2.7 firmware again and give it a try. Will come back with updates and photos.

ok

So I downloaded version 2.7 again and the same situation happened. No modbus and no mqtt data is sent. Cannot read modbus data even with Kincony Smart Board Controller. In MQTT Explorer no mqtt data is received even when short DI with GND, mqtt no feedback. I have attached some photos from all the configuration.
After this I've reverted the firmware back to v1.14 and immediately received mqtt data. The problem is that now with 1.14 modbus data cannot be read. I've tried in node-red and in Kincony SBC. 
Hope you can help. Thank you.

ok, we will test with V2.7. but old version also not use for read modbus rs485 data. RS485 port only use for kincony RS485 modbus energy meter, not use for others.

I appreciate that you checked it. I'm using it with the mqtt addon and home assistant. No configuration is changed in HA and when I downgrading the COLB firmware to 1.14 it starts working instantly. Strange. What could be the problem?
The modbus is used to collect data from Kincony power meter. No other device is connected to modbus.

[admin]

if you use home assistant, you can use a USB-RS485 adapter, or use by KC868-Server(because it have RS485 port). config yaml for KinCony RS485 modbus energy meter directly. Not need to use Node-Red.

about update new COLB problem. maybe you can change to another IP address for COLB controller.
