I know there are some communications issues with the Gas Smart Meter that have stopped it sending readings but I'm unclear exactly where the issue lies.
I understand the electricity smart meter has the WAN (2G/GSM) component, and the gas meter send its readings to the electricity meter by HAN (Zigbee/2.4ghz) to then be relayed to the provider. Is my understanding of this correct?
I removed the IHD (the Pipit 500) as it stopped working. Would having the IHD in place (its about mid way between the meters) help to relay the Zigbee signal from one meter to another?
Can I get a better IHD? What about if I buy one off of eBay, or can I bribe the provider to provide a better quality product?
Would any generic Zigbee relay/booster device work between the meters or does it need to be a specific Smart Meter product?
Would adding an external WAN antenna to the electricity meter do anything to improve communications with the Gas meter? (I assume no.)
Will SMETS2 meters have higher gain signal between meters that could potentially solve this problem?
Thanks in advance all!

Some pretty technical questions here! Thought I'd jump in and offer some answers.
- Your understanding of the comms between devices is correct!
- Your IHD will need reconnecting if you removed it. Our team can do this for you if you give them a ring. Yes - having the IHD between the meters will help boost signal.
- We are now rolling out the Chameleon IHD with new smart meter installs. You can have a look at how it works here. Unfortunately due to stock levels, we can't currently issue replacement Chameleons for all customers with Pipits.
- Any Zigbee device would in theory boost the signal, as long as we have connected it to the HAN network. We generally wouldn't connect a non-OVO CAD device as we can't be sure of the security implications. Currently, we'd only connect the Pipit or Chameleon to your HAN.
- An external antenna could only be added to the electricity meter, as this communicates to OVO via WAN. The gas meter does not use WAN, so this wouldn't improve signal between gas and elec.
- As far as I know (though I will ask for further clarification and get back to you), SMETS2 will operate on the same network, so connectivity would be the same. That said, mobile networks across the UK are continually being upgraded, so signal should get better and better over time.
Hope this helps for now!
