Ah, so not exactly as it sounds then, interesting.

I guess that’s just what it sounds like it is? Never heard of it before.

🤣🤣🤣 Oh yes, I’d forgotten about that.

Something like that it seems, but the labels don't indicate 1 and 0. You and me both! I suspect it's 127.5 at least then 255 makes some sense as it's 2 x 127.5 but apart from that who knows whats going on? Good question. Well phrased. Deserves an answer! As you seem to be located in the land of Brink manufacture, could you go and knock on their door and ask them to explain themselves. As far as I'm concerned the frequent flipping from 0 to 128 to 255 and back again is completely abnormal behaviour and must be some kind of software glitch. At this time of year I wouldn't expect to see the bypass move at all so even the early trace of 1 to 0 and back again strikes me as odd.

Yes, on one occasion, but with the evidence of future events it may well have been that I just wasn't giving the inverter sufficient time to revert, for some reason the settings don't revert straight away when the Axle event is finished - at least for me. I now set a reminder for 15 mins after the event has finished and check the inverter settings then, all's been fine since.

👋Calling any Brink Flair MVHR owners 👋 Could someone send me an image of the ‘Status Bypass Valve’ (like the ones I posted above) from a working unit so I can compare and contrast? Thanks in advance. ~~~ Advice from the original supplier “just replace the bypass, they’re cheap as chips”. Which is all well and good, but why it failed in the first place seemed to be of little interest to them. To my mind I fit the brand new, cheap as chips replacement and it fails in exactly the same way in a few months/years time so what’s the point. I’ve got a fair few months to mull this over as I don’t think summer will need bypassing for a while, the unit is reassembled with the bypass closed and the bypass motor disconnected. So all’s good at the moment. I think.

Well there certainly has been some strange bypass behaviour according to the available data. More 'opening' and 'closing' than I would have expected to see before it went nuts around lunchtime of the 26th and decided to thrash itself to death. It looks like my glue repair took a bit of a beating before finally giving up the ghost and shuffling off this mortal coil 3 days later.

Ah, in case of power outage I presume? My inverter is set to stop export when the battery reaches 10% SoC for just such an eventuality, I guess that would stop the export if Axle are taking the juice but not at all certain.

B*ggery b*llox. Well, it looks like my repair has failed. I’ll have to dismantle it in the morning to confirm. I wonder if it’s a software issue and the motor keeps trying to turn in the same direction after the flapper has reached its movement limit??

Doesn’t it just! Mind you, I suppose the thing we have done is invest in a battery, the VPP could not exist without that.

You can, but under current tariffs why would you? Axle buy it for £1/kWh, if I need to buy it back at peak rate it’ll cost me around 30p/kWh so effectively I’ve only got 70p/kWh instead of the whole £1. That’ll do nicely.

All good here, signed up beginning of May (£25), one referral bonus (£25) and total export credit to date £105.73 from Axle. I do nothing, just let it get on with its thing when it wants to. I normally get around £5:50 per 1hr event and £11:00 per 2hr event, only had one of those so far.

Back up and running, fault code cleared. It’s a real mystery. It does a lot of moving during power up, half open, half closed, fully open, fully closed finally reverting to fully closed (or the other way around, but a lot of moving nonetheless). I’d add a video but it’s too big, is that 2MB limit a new thing? Or have my pictures/videos got bigger??

I’ll keep an eye on that but I’m sure it’s been opening and closing a fair bit over the summer, I generally just leave it to do its thing but if I select ‘night ventilation mode’ I’m pretty sure selects the bypass open, I’ll have to check the manual. Anyway, all glued up so I’ll chuck it back together and hope for the best, if it fails I think I’ll get a flapper thingy 3d printed because I don’t suspect Brink we’ll sell me just that little bit.

It certainly does and certainly is. I just can’t fathom why there would be any resistance to the flapper moving.
