Hi. I am new to the forum.
I have been with OVO for 10 months and I have had 2 SMETS2 meters fitted not long after I moved to OVO.
Unfortunately, the system has never worked properly since installation !
What used to happen intermittently was one of 2 scenarios:
The WAN light used to go off and my smart meter would stop sending my meter readings to OVO or the HAN light used to go off and my IHD would stop working with the message "waiting for current data" being displayed.
Last week all 4 lights (including the WAN and HAN lights) continued to work on the meter (they all flashed on once every 4 or 5 seconds) and yet my IHD stopped working which had never happened before whilst all 4 lights were working !?
A couple of days ago the IHD came back on again but despite all 4 lights still displaying on the meter, my meter readings don't update on the OVO app.
How is this ?
I thought if the WAN (Wide Area Network) light was on, my electric meter could communicate my meter readings to OVO.
Also I can't understand why last time, my IHD lost the wifi signal in the first place with the HAN (Home Area Network) light being on ?
By the way I have a Chameleon IHD and regarding the wifi signal on the IHD, it is a strong signal (4 bars) as my IHD is only around 5 meters from the meter with only an internal wall (4" thick) which has no effect on the wifi signal.
The lowest it goes down to is 3 bars.
Any feedback would be much appreciated.

WAN, MESH and HAN lights:
WAN - Wide Area Network
Shows your communication hub’s ability to communicate with your supplier. Flashing indicated a connection.
MESH - Mesh Communications Network
If you have a SK2 or SKU3 type of Communications Hub, then both WAN and MESH are active, and will display the slow-flash from these indicators if all is well.
If you have a SKU1 (85% of houses do), then the MESH indicator will always be off because that section of electronics isn’t present.
HAN - Home Area Network
This light shows the connection status of your electricity meter, gas meter and IHD with your communications hub on the HAN (Home Area Network).
See this topic for a complete guide on what each hub indicate light means
What the lights mean when there’s a fault:
Now let’s just separate out the different faults you’ve been seeing.
A; A solid WAN may indicate a lack of communication with OVO. the WAN and/or HAN indicator going off is very unusual. In the case of a fault on either of these networks, the correct flash rate should be “medium” (roughly once every 2 seconds).
It’s unlikely that you’ll ever actually see the “High” flash rate because this occurs when the Communications Hub is starting up and trying to find the networks.
An indicator that’s completely off means that this part of the code isn’t operational at all. Most customers have SKU1-type SMETS2 meters, in which case the Mesh indicator will be off. Ie there is no Mesh network for this model.
B; It isn’t unusual to have an IHD not displaying correct data but still have the HAN indicator showing the usual slow-flash. The indicator only shows that the Zigbee carrier frequency is alive. Frustratingly it doesn’t mean that any useful data is being transferred!
The same is true of the signal-strength bars on your Chameleon IHD. They will still be present even if the code receiving/interpreting data from the Comms Hub has committed suicide.
C; In similar fashion, just because the WAN indicator is in slow-flash mode doesn’t mean that OVO are actually receiving your data. Since you’re in the Telefonica territory, the WAN merely informs you that the carrier between you and the mast is alive.
The only way to tell if OVO is successfully receiving data from your site is to login to your online account and view your Usage statistics.
So there’s some initial feedback on what you’ve carefully described to us. And you might also want to read this topic where a few of us have recently been discussing IHD-related errors, and this topic is a great one for the ‘Waiting for current data’ issue
How to confirm no communication from solid WAN
If the WAN on your meter is solid, and you’ve confirmed no usage data on your online account, you can test your mobile phone signal right next to the meter. If you have zero signal, that would explain it. Then test mobile signal a few feet away from the meter, above, or to the side. If signal improves, an aerial might fix your meter’s communication issue. Reach out to support to book in an aerial fitting. They’re on Facebook, Twitter and our Help Centre has online chat!
