Runbefore commands can help you solve some meter related readout problems, such as;
meters that reply incorrectly, meters stuck in loops, meters not replying with the correct telegram first etc.
Enter meters -> mbus settings -> scroll down and allow advanced settings.
scroll down further to the runbefore command.
Select the one you want from the droplist.
Observe that our cmex50 and cmi5110 wireless mbus recievers will be factoryreset when recieving the resetb0 command.
