Hi I have this “Develco Products A/S EMIZB-132” adapter for reading my energy meter off the type Norwegian AMS.
This is a Zigbee adapter, but doesn’t have an device handler in ZHA. Can any one explain to me how to make one ?
I understand this is some sort off ZHAquirk, I have the information on which zigbee clusters it uses. But I don’t know how to connect this attributes to variables that are displayable in Home assitant in the correcct way.
Hi
Did you manage to get this working?
I have plugged this sensor, and I get strange data. Home assistant returns a smart energy metering that seems to be twice the active power. The most frustrating is that I can read total_active_power in the the clusters, but I have no idea how to get that into home assistant.
I have t his adapter too. The problem with this device is that it has a LOT of sensors, and they have values stored in the code with what you need to devide or multiply each sensor output to get the real output. I hope someone can make an integration for it but I have not found any yet that works.
I also bought this adapter and struggled with around 1,93 times the actual consumption (similar to @ben4790), actually I had agreed with Elektroimportøren to return the EMIZB-132 and exchange it for an EVA HAN-adapter tomorrow 
But I decided to do a bit more investigation this evening and with luck!
I dived into the diagnostics log for the device and located this:
"attribute_name": "divisor", "value": 516
My math-head quickly translated that to around the same as 1000/516 = ca 1,93 
And yes, taking the summation_delivered / (1000/516) gave me pretty much the same total as on the display on the meter.
As I do not know how to set this attribute using ZHA Toolkit (should probably be possible), I made two new sensors using Helpers and the template integration:
{{ (states('sensor.emizb_132_instantaneous_demand') | float) * 516 / 1000 }}
{{ (states('sensor.emizb_132_summation_delivered') | float) * 516 / 1000 }}
Hopefully this can help others with this adapter.
