Honeywell CH/DHW via RF - evohome, sundial, hometronics, chronotherm

Everything seems OK here. Can you be more specific?

@zxdavb ignore me, sorry. Just fully reset HA and all appears good.

Same here. With 0.7.5 and HGI80 after some time the temperature sensors are no longer updated. Setting the temperature works normally and evohome responds directly to those values.

Hmmmā€¦ I can have a look at it perhapsā€¦

Iā€™m seeing my Hot Water relay becoming intermittently Unavailable which wasnā€™t the case previously. @zxdavb from what I tell something has regressed post with 0.7.5 with sensors refreshing.

Guysā€¦

The RAMSES_II protocol is not completely understood (there is no documentation for it). I probably know it better than most, and I am still learning. Almost every day, it seems, I learn something newā€¦

In this instance, the question may be this: how long should I keep a packet in memory for, before the data it contains is to be considered stale? For example, if itā€™s a temperature packet from a thermostat, then after a hour, the data within that packet cannot reasonably be any value.

Or: if a device sends a packet every 15 minutes, and the last such packet I seen by evohome_rf was >30 mins ago, is it reasonable to assume that device is offline?

Many of these ā€˜timeoutā€™ values are known, many are not - maybe I have the wrong value for one of themā€¦

In all such cases, people can help by sending me packet logs when things donā€™t behave as expected & I can work out yet more of how the protocol worksā€¦

It may be the case here that a packet is sent every hour, and Iā€™m expecting it every 15 minutes? Dunno.

What Iā€™m trying to say, is:

Generally, I need to see packet logs please. And where relevant, could I have an entity_id?

Presently, I have a to-do list a mile longā€¦ if people take the effort to send me a packet log, I will usually take the time to address their problem. If I donā€™t have a packet log, then I cannot re-produce the issue, and I will not really be in a position to help.

@zxdavb I restored a 6.6 snapshot which used to behave properly but now also loses sensor updates after a half hour or so. Must be something local with my HGI80 or Proxmox config I now suspect instead of the 7.5 version. So to prevent you chasing ghostsā€¦

Thanks for the feedback - donā€™t worry, I wasnā€™t chasing anything, as I didnā€™t have a packet.log!

Well the packet.log just stops at some point in time (in this case 15:19 and a restart of the HA core at 19:42):

I donā€™t think I have anything to offer you on this - I think proxmox is a type of VM host, no?

I can strongly recommend this USB dongle - it has been optimized for evohome_rf - sold by the team who wrote (most of) & maintains evofw3.

ATMega32u4 + 868MHz cc1101 USB stick

The price is only a little more than a nanoCUL from eBay, but it is a much better hardware platform.

To be clear, the nanoCUL will work, but may well be a technological dead end in the longer term; and a HGI80 is just too expensiveā€¦

Yeah, perhaps the USB controller on the host died (happens sometimes on my X399 platform, the HGI80 had to be power cycled due to the overload issue, or somewhere in the Proxmox plumbing. It has kept working since last night and will not touch it any time soon (or if there are nice new features to test :slight_smile: )

sadly that i just bought the nanocul a few weeks ago, maybe something for the start post and github? there is the recommendation the nanocul.

I will do - they are not yet on sale - store only opened yesterday - I havenā€™t got one yet - people have been testing them for me!

Can the person who had an issue getting their HR80s into their schema remind me who they are?

Are you serious :frowning: I just received my nanocul today!!

Iā€™m having real trouble setting up this device. I canā€™t find any proper documentation on how to flash the firmware.
I downloaded arduino IDE on a windows 10 machine, connected the usb device.
Followed all the steps here: https://github.com/ghoti57/evofw3/blob/master/README.md
ā€¦ and then what?
After the last step " Use Tools , Pinout to select the appropriate connection variant." what am I supposed to do? I clicked ā€œtoolsā€ > ā€œBurn boatloaderā€ but that just keeps giving me an errorā€¦

This is not really the way to ask for help - and Iā€™m not even the one that has dedicated sh*t loads of my time, to make this entire thing a possibility.

Thank you, that was very helpful. Itā€™s difficult to find these posts in such a large thread.

My apologies if my remark has offended anybody. I do realize how much time goes into such projects.
Under no way am I showing criticism to the developer or anybody else. Iā€™m just voicing my disappointment into the fact that Iā€™ve waited an incredibly long time to order this nanocul and now that I finally made the step, it turns out to be outdated at the exact same moment.

Itā€™s nobodyā€™s fault, I was just going like ā€œoh come onā€¦ !ā€
