Supports automatic firmware updates, with the following additions:
- user can disable automatic firmware updates via the web interface
- user can disable internal pullup resistor on HAN DATA pin via web interface
Point 1 above means you can manually control when and what firmware to update to.
Point 2 above means you can get Currently One to work with Kaifa’s & Sanxing’s meters MA304H4E and S34U18 respectively. Disable internal pullup for those meters.
For Aidan on the other hand, you may have to enable internal pullup (uncheck disable) to be able to read HAN data.
