[OpenTRV-interest] Frequent non-communication periods between hub and its valve

[Damon Hart-Davis]

Hi,

OK, thanks for that.

I’m running a fair number of units here as you might imagine and though I see some funnies, I have seen nothing as spectacular as that.  Eeek!

(Sorry, STILL buried under other bits of work!)

Can you possibly remind me which version of the code you are using (eg from the start of the boot chatter) and I’ll open a JIRA at least to track this.

Thanks very much for spotting this.  I can conceive of ways in which it might happen, but I already attempt to minimise the risk.  And it is just possible that you simply have a dodgy radio module, though I’m more inclined in the first instance to blame my coding!

Rgds

Damon

There seemed to be a TOTAL lack of any actual form of transmission or reception which continued until the hub was hard power reset. I cannot explain how this happened but by inference lack of Tx and Rx occurred at the same time; ANY form of Rx observed from the leaf ceased (though the leaf still communicated with its own FHT8V) and at the same time similarly the hubs FHT8V ceased to receive transmissions. I do not know what it is possible for OpenTRV to do to monitor for this situation?
