justifying cost of Eddi installation?

No, its the normal digital meter with D/N before smart meters came in. Was on Energia now on Flogas, all providers must pay deemed AFAIK and its not dependent on whether its 24 hour or D/N just that its NOT a smart meter because non smart meters cant tell how much you export.

My bad, didnt know that

Must be for new signups or contract renewals then, because as per current CRU and ESBn agreed methodology, the entitlement to FIT is based on eligibility for smart meter. All MCC01 are now Eligible so would not qualify. Unless your location due to cell coverage or something was marked as ineligible I'd suspect you'd be grandfathered in or something. I'd probably keep schtum just in case! (See below, criteria defined by meter type and not by location, with an opt back in by location)

Deemed export: To be eligible for remuneration based on deemed export quantities, a renewables self-consumer must meet the following criteria: • the renewables self-consumer must meet the definition included in REDII; • the renewables-self consumer must have installed microgeneration and must have • informed ESBN of their intention to install microgeneration via a declaration using the NC6 or equivalent form; and • their meter type is not eligible for a smart meter installation as part of the ESBN led deployment approach under the NSMP at this time or they are eligible for a smart meter installation but unable to have a smart meter installed for other reasons outside of their control. Under the deemed export quantity arrangements, the deemed quantity calculated and provisioned by ESBN is the final determination of the quantity of export for which customers are to be paid by suppliers

My meters are inside the house, maybe they reckon there'd be connection issues, though I would think it'd be ok with 2g?

Anyway, that's just another reason why I don't want to give up my old meter 😉

They need 2G cell coverage, and apparently they send updates every 30 minutes back to the mothership. There are different MCC for smart meters, 12 and 16, and the difference is the quality of cell coverage apparently.

Putting FIT aside for a minute your last sentence is pertinent to a lot of people, in my case I'll soon have a D/N meter which strengthens the case for an Eddi (guaranteed payment no matter what).

yeah at 800 its expensive... so it really depends if you want it or dont, like all purchases.. very few things. pay for themselves.. it doesnt have to be the only criteria.. i doubt ours will ever pay for itself... and i use the gas to heat the water tank from 6 to 7 every morning anyway but the eddi does boost it on sunny afternoon.. with a new insulated hot water tank the water stays fairly warm anyway so it doesnt need a lot of boosting.. also the geek in me just likes seeing it in the app and having another home automation device
