yes you need to have triggers. Otherwise it wont know when to switch.

Something like this should work. In your case other way around.

But if you use it as 1'st of every month then it  will update the values at 29/30/31 at 00:00.

Example: Ive made a scheduler that will start the program what then will send out the meters values.

bOS calculates its time like so: time trigger 0:0 for 1 day of month means the start of the day not the end... For you it will send out the values at the end of the last day of the month. at least so far it has worked like that.


I've noticed that when you have connected with a administrators account and then change back to regular user, it ask for it sometimes or tells you the password may be incorrect at the first login attempt, second login works with no password changes. This has been happening on 4.4.4 too, and i think its because bOS does not copy the device to the users account when its already under admins. 
Have you tried to delete the device and then reconnect it?

Strangely none of my current projects are affected with it right now. I tested both versions 4.6.20 and 4.4.4

Just did a new test, closed the app and reopened it, checked different buildings. All logged me in without any errors. Have you tried a different device too?  Or have you looked at the devices token's do they dissapear when you log out the device? You could also try reloading the server from the configurator, see if that helps.

Reporting in that this does not happen to my projects. Maybe somebody is deleting your device from the users menu?

Well ok, it just seemed to me that it wouldn't want to poll other registers, so far its ok, i will keep my eye on it though. 

It also may be just .actualvolume because you already are sending /volume with the first part of the command. Have you tested it on a web browser, does it change the volume when you paste the command in there?

Try to add a . in front of the command see if it helps like ".volume.actualvolume" Also good sites to check if your command works are or

If you know the modbus registers then it should work with bOS with no problems. If you dont know the register you could use a RMMS modbus master simulator to figure them out.

Add modbus driver under the devices in bOS, then choose the correct COM port and start adding the registers for the relays.
