<div class="markdown_content"><p>Hi Edwin<br/> Even this is old thread, but it actually saved my day.<br/> The code you wrote actually works very well , I saved all my retained tags even if PI4 is powered off without using UPS.<br/> For whoever wants to make retain variables works, please look carefully on the first page. Edwin's sample code works perfectly.</p></div>

<div class="markdown_content"><p>Hi Edwin,<br/> Did you test the bug?<br/> I tried the project with a 32 bit PC (Win XP), V3.5 SP7 Patch 3. Raspberry PI same. The retain variables stores their values after a power down. <br/> Regards, Donát.</p></div>
