Gas Credit L&G TSG: Step 5 – HAN join continued

Once HAN Join is successful (allow maximum of 7 mins from pressing Commission button on ToughPad), press button A when the 'Join Ok' message is seen on the Meter display.

However, due to processing time, the HAN join process is likely to have a need to be repeated. To repeat this, press button 'A' (red) to try a second HAN Join Attempt and repeat every minute for a maximum of 7 minutes.


The HAN LED will go to MFF (up to 10 mins) and GAS LED will go to LFF.

Ok, proceed to step 6

Having problems? See our Troubleshooting Guide below.


There are a few issues you may encounter:

'Join Failed' message is shown after 7 minutes.
Gas Meter display doesn't show 'Join HAN' message (within 7 minutes).
HAN LED doesn't transition to MFF.
GAS LED doesn't transition to LFF.


Installer actions to rectify any of these issues:

  • Press the ‘De-whitelist’ button on ToughPad and change Gas Meter once. Then go back to step 1.
  • If this is successful, proceed to step 6.
  • If unsuccessful, abort SMETS2 Gas Meter install 'Signal Strength (HAN)'. Leave legacy Gas Meter and return SMETS2 Gas Meter to vehicle as this can be re-used on another job. DO NOT return Gas meter to 3PL via pellipod locker.
  • Call SMETS2 back office commissioning team on 0800 096 5070 to commission PPMID. Ensure all PPMID details are populated on ToughPad.
