Zappi says "Master Lost"

[Giller]

Not sure, from the terminology I'd say the Eddi is the master to get priority, but that’s just a theory. I do know from what I’ve read it’s the Eddi is the master, must be a good reason for that.

As for the Harvi, if that was the gizmo your guy fitted I’d say i will be near the circuit board as it’s powered from a ct clamp, when we had the Zappi installed it came with a Harvi in the box.

Depends on which model you have, the 2.0 did not have integral connectivity but the 2.1 and newer do.

• Built-in Wi-Fi & Ethernet: The Zappi 2.1 features an RJ45 Ethernet port and 2.4GHz 802.11bgn Wi-Fi, allowing it to connect directly to a home router.

If it is a v2.0, what about running the cable then having an access point, better than plug in wifi extender.

Mines a 2.1 so it's built in, as for running a cable the router is no where near and I'm more than happy with the range extender, connection is rock solid.

I'm fairly sure I don't have a Harvi. I was wondering if changing the Zappi to be the master might help?

My understanding is the master must have the ct clamp connection so to make the zappi the master it would need the ct clamp switched to it first.

How far away is the Eddi?

The Eddi was set to be the master, but Duward (my installer) said that was just because it was inside the house so I didn't have to go out to the garage if anything needed to be done to the master. I was wondering whether setting the Zappi as the master would help.

Things have developed a bit more and I'm still baffled. This morning I discovered some kind neighbour had shut the garage door, but presumably after the car had finished charging as the app read "EV is full". The issue was still present.

It's a double garage with two doors. If the door nearest the house was open, the Zappi connected and behaved normally. Shut that door and "Master Lost". The other door, the one the car is behind, made no difference. Opening it didn't clear the problem.

I picked up an email from Duward in which he suggested logging out of the MyEnergi app and logging back in. I thought this was nuts because how could that cure a signal strength issue? But I did it and what do you know? The problem went away. Immediately.

I'm still sceptical, for obvious reasons, but so far so good. I'll have to charge again tonight because I have to take the car to Galashiels (70 mile round trip) for its service tomorrow, following a 60-mile trip to the dentist this evening. So if it starts playing silly buggers again, Duward is going to get another email.

Hard to guess how far the Eddi is from the Zappi as the former is in the fuse cupboard in the house and the latter in the garage, on the outside wall. Forty feet maybe? Fifty?

Sounds more and more like a signal strength issue to me, I'm not an expert but I read things.

The idea of having the Eddi as the master seems sound as it's inside the house etc, and in there it should get a stronger wi fi connection that the Zappi which however is not the case, but what is the wi fi strength at the Zappi compared to the Eddi?

 

[Rolfe]

Dunno. If this comes back again then that's one of the things I need to find out. I would say though that the Eddi is a lot nearer the router than the Zappi, so it's pretty much inevitable that the Eddi has the stronger signal.

 

[Diggsy]

I take it your Zappi’s firmware is up to date?

Also, I can tell you that the WiFi range of the Zappi isn’t great. I have a WiFi disc on the inside of the wall where my Zappi is (literally directly behind it) and even then it doesn’t get a great signal. Shows -73db on the WiFi app which is far from ideal.

Just thinking actually - the Eddi connects to the Zappi via RF, if I recall correctly. That being the case, is there anything interfering with that signal? Have you installed any new smart plugs/bulbs etc that might be using RF, which could be causing interference?

 

[Rolfe]

No, nothing has changed. And right now the whole thing is completely normal. The car is in the garage with the doors closed, plugged into the Zappi waiting for 11.30 (I'm not going to risk a Smart charge right now), and the Zappi is showing "waiting for surplus" as it always does. I haven't seen "Master Lost" since I logged out of the app and back in again.

 

[Rolfe]

Aaaaand, we're fine. The schedule was completed, the charge didn't drop at all, and Zappi says 3.12 kwh was delivered. That's about £1, so well worth it. The car has put on 5% and 11 miles of range.

I'm not sure it's even worth trying any of the other things. Is it possible it was all being caused by an intermittent issue with the communication between the Zappi and the Eddi, and the shenanigans at the GoZero charger yesterday were pure coincidence? Maybe?

In fact my peak-time electricity consumption for that day came to 41p. Of course the Zappi took over half of its power from the battery, which promptly recharged from the solar. So I lost a wee bit of export as well, but it wasn't much.
