+### reset localpw
+If when the above command is run, localpw is blank, you can reset it using the following instructions. This does not appear to interfer with the cloud connection as it does not use the localpw after set up. (Tested firmware version 42.19 on the first generation purei9, use at your own risk)
+
+1. Flip your purei9 onto its back.
+2. Connect your laptop to its network (Network Name: 3Dvision XXX-XXXX).
+3. Search its network to local its ip address (will be different to its normal ip on your home network).
+	```
+	$ python -m purei9_unofficial local find
+	+---------------+--------------------------+---------+
+	|   Address     |         RobotID          |  Name   |
+	+---------------+--------------------------+---------+
+	| 192.168.6.1   | 900395798357985798375972 | Cleaner |
+	+---------------+--------------------------+---------+
+	```
+4. Run the setlocalpw command, the command below would set it to 01234567
+	```
+	$ python3 -m purei9_unofficial local -a 192.168.6.1 -l 01234567 setlocalpw
+	```
+5. Flip the purei9 back over and put on charge.
+6. From here local commands should work.
+
+Note there may be a small delay between the robot being put on its back and the network being available. As well as between putting it on charge and the local commands being available.
+

 You can also use the tool to locate any robots in the network
