Ok, sounds good.
We don’t have an option for firmware upgrade of the CID on our website, but you could purchase the EZSrve upgrade and put in the notes that you want the release candidate SE coordinator USB-CID version and that you spoke to me. This would cover the upgrade as well as shipping back to you, assuming you’re in the US.
You did mention, coordinator “or not”…and with that in mind, we do have a ZOE-VIPD firmware which is an SE router that I could put on the stick as well. If you’d prefer a router, because you’re using a meter as the coordinator, we could do that too. Just indicate in the notes when you purchase the upgrade and send the device to our address, listed on the website.
