Modbus error handling new features

Jürgen Jürgenson 4 years ago in Devices / Modbus updated by ComfortClick Support 4 months ago 8


I had a small problem with modbus connection that seemed to be all fine(Was connected and no errors in debug), but actually it didn't update values, but i had the error handling setting set to hide. 

Now here's my question if it's set to hide and there is some error does it drop the connection? Or will it still reconnect after the error just doesn't log the error?

I was looking at the diagnostics/debug and it didn't show me any timeouts but it looked like it only was asking 1 register for updates. after i disabled it and re-enabled it started to talk to me again(Started to poll/update all the registers). So right now i left the error handling to reconnect.(Only reason i left it in hide mode was so i could test registers that didn't respond for some reason, now i just turned off cyclical read on them) Modbus connection was "offline" for 2 days.

Also it would be awesome if we could disable/enable modbus driver from the visualization too,  I haven't found a way to do it. We can see the status of the driver that's it.

Error not reconnect Modbus TCP.

APP MOD 4 months ago in Devices / Modbus 0

I am currently experiencing an issue where the Modbus TCP connection does not automatically reconnect after being disconnected. The bOS still shows the status as "true", but I have to manually enable and disable it to get it to work again. This error occurred after I updated the bOS server to version 4.10.8. Is there any way to fix this?


We are about to implement a project on a hotel building BMS system. We have some questions as follows.

LÊ NHÂN 6 months ago in Devices / Modbus updated 6 months ago 2

We are writing to inquire about the following topics for our upcoming hotel building BMS project:

  • What type of Comfortclick device is recommended for a hotel building BMS system?
  • How many devices does Comfortclick support to connect with the Modbus TCP protocol?
  • Can 2 devices be managed remotely on the same bOS interface account at the same time?

We appreciate your assistance.


Comfort Click Jigsaw 3 and PLC bad communication

Milos Jovanovic 6 months ago in Devices / Modbus updated by Jürgen Jürgenson 6 months ago 5

I would like to address an issue regarding the Comfort Click Jigsaw 3 device and the PLC controller. Communication is carried out through the Modbus TCP protocol. The initial problem involves the mobile application displaying the online status of the Comfort Click device, but it lacks successful communication with the PLC controller. Changes in values within the application do not reflect corresponding alterations on the PLC controller. This issue has been temporarily resolved by halting the operation of the PLC and restarting it, but it reoccurs after some time.

The second problem occurred today in the form of the unavailability of the mobile application. When attempting to log in to the device, an error is displayed: "Error connecting to server." Additionally, on the Comfort Click web platform, I noticed that the status of my controller is marked as offline.

I kindly request your expertise in diagnosing and resolving these issues.

change modbus setting through formula

Joost vB 9 months ago in Devices / Modbus updated by Andy Gill 8 months ago 5

Today my home has had a power outage. 

My solar inverters are connected to my Jigsaw through modbus. It appears the modbus connection isn't restored after the outage, possibly because the inverers restart shortly after the Jigsaw-modbus is activated.

The solution seems to be to deactivate and reactivate the modbus through bOS (settings > driver > enable > false/true).

I'm now trying to make a fomula which is triggered after a reboot of bOS. The formula should deactivate and reactivate the modbus driver.

Any tips on how to deactivate and reactivate the modbus?

Or are there any other ways to reactivate the modbus connection?

Thanks for your support! 


Modbus 32int variable to KNX address

Claudio Lauriola 9 months ago in Devices / Modbus updated 9 months ago 1


I need to export a modbus variable (Integer 32 bit signed) to KNX address. 

Unfortunately none of 4 byte KNX objects (signed, unsigned, float) can be link to that modbus variable. Have you any suggestion please?
